This article systematically analyzes the historical evolution of the name, origin, quality evaluation, harvesting, processing and other aspects of Picrorhizae Rhizoma by referring to the medical books, prescription books, and other documents of the past dynasties, combined with relevant modern research materials, in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history, Huhuanglian has been used as its official name, and there are also aliases such as Gehu Luze, Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times, Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions, and also produced in China, mainly in Xizang. In ancient times, it was harvested and dried in early August of the lunar calendar, while in modern times, it is mostly harvested from July to September, with the best quality being those with thick and crispy rhizomes without impurities, and bitter taste. Throughout history, Picrorhizae Rhizoma was collected, washed, sliced, and dried before being used as a raw material for medicine, it has a bitter and cold taste, mainly used to treat bone steaming, hot flashes, infantile chancre fever, and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results, it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia, or the rhizomes of P. kurrooa, can be used in famous classical formulas containing this medicinal herb, which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements, the dried raw products are used as medicine.

ObjectiveTo investigate the modifiable areal unit problem (MAUP) in the spatial pattern of Pseudostellaria heterophylla production regions and reveal the impact of statistical scales on the spatial distribution characteristics of this medicinal plant species. MethodsUsing multi-source data (literature records, field surveys, and statistical data), we systematically analyzed the spatial patterns across three administrative levels (provincial, prefectural, and county scales). Spatial autocorrelation (Moran's I) analysis, high-low clustering (Getis-Ord General G), and hot/cold spot analysis (Getis-Ord Gi*) were employed. ResultsThe literature-based analysis showed that the production regions of P. heterophylla presented random distribution on the provincial scale and significant aggregation on the prefectural scale. The field survey data showed that the production regions displayed random distribution on the provincial scale but significant aggregation on both prefectural and county scales. The statistical data revealed that the production regions lacked spatial autocorrelation on the provincial scale but demonstrated significant aggregation on prefectural and county scales. ConclusionMAUP effects have substantive implications for understanding and decision-making in the arrangement of medicinal plant production regions. The county scale proves to be the most sensitive and explanatory level for analyzing the spatial pattern of P. heterophylla production regions, providing a critical foundation for habitat modeling, suitability evaluation, and ecological cultivation planning of medicinal plants.

By systematically combing ancient and modern literature, this paper examined Tribuli Fructus and Astragali Complanati Semen(ACS) used in the famous classical formulas from the aspects of name, origin, production area, harvesting and processing, clinical efficacy, so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology, and there were nicknames such as Baijili, Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas, and there were nicknames such as Baijili, Shayuan Jili and Tongjili. Because both of them had the name of Baijili, confusion began to appear in the Song dynasty. In ancient and modern times, the main origin of Tribuli Fructus were Tribulus terrestris, and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu, but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part, harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times, and the plump, firm texture, grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing, while modern commonly used is purified, fried and salt-processed. The ancient records of Tribuli Fructus were spicy, bitter, and warm in nature, with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders, improving vision, promoting muscle growth, and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today, the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed, traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter, followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior, while modern standards prioritize plump, uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying, while modern practice commonly employs purification methods. In terms of medicinal properties, the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus, its effects were thus regarded as equivalent to those of Tribuli Fructus, serving as the medicine for treating wind disorders, additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang, solidify sperm and reduce urine, nourish the liver and brighten the eye, etc. Based on the textual research results, it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials, we should pay attention to the specific reference object of Baijili, T. terrestris and A. complanatus should be identified and selected, and the processing method should be in accordance with the requirements of the formulas.

ObjectiveTo conduct a systematic comparative study on wild and cultivated Codonopsis pilosula(CP) from three aspects, including characters, microscopy, and contents of primary and secondary metabolites. MethodWild and cultivated CP samples were collected, their characters were measured using vernier caliper, tape measure and balance, the paraffin sections were stained with safranin-fixed green dyeing, and their microstructure were observed under the optical microscope. The content of alcohol-soluble extracts in wild and cultivated CP was determined according to the method for determination of extract under CP in the 2020 edition of Chinese Pharmacopoeia, the starch content was determined by anthrone colorimetry, the content of total polysaccharides was determined by kit method, Fiber analyzer was used to determine the content of fiber components, and ultra performance liquid chromatography(UPLC) was used to determine the content of monosaccharides, disaccharides and some secondary metabolites. Multivariate statistical analysis methods such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed to screen key differential components between wild and cultivated CP on the basis of variable importance in the projection(VIP) value>1 and P<0.05. ResultIn terms of morphological characteristics, the "lion's head-like" shape, longitudinal wrinkles, and circumferential wrinkles below the root cap of wild CP were more pronounced in wild CP compared to the cultivated ones. Regarding transverse sectional features, wild CP had more fissures on the outer side of the cortex and a larger duramen. Under microscopic examination, wild CP had more stone cells, a larger proportion of xylem, and the presence of cork cells arranged in rings in the xylem, while cultivated CP has a larger proportion of phloem, smaller vessel diameters, and a more loosely arranged vascular system. In terms of primary metabolites, the contents of 45% ethanol-soluble extract and total polysaccharides in cultivated CP were significantly higher than those in the wild ones(P<0.05), the contents of lignin, hemicellulose, cellulose, fructose and glucose in wild CP were significantly higher than those in the cultivated ones(P<0.05), while sucrose content in the cultivated CP was significantly higher than that in the wild ones(P<0.05). Concerning secondary metabolites, the contents of tryptophan and tangshenoside Ⅰ in cultivated CP were significantly higher than those in the wild ones(P<0.05), whereas the contents of lobetyolinin, lobetyol and atractylenolide Ⅲ in wild CP were significantly higher than those in the cultivated ones(P<0.05). ConclusionThere are significant differences between wild and cultivated CP in terms of morphological characteristics, microscopic features and chemical composition. Glucose, fructose, sucrose, tangshenoside Ⅰ, tryptophan and cellulose components are the key differential components between wild and cultivated CP. Wild CP contains more polyacetylenes and fructose, whereas cultivated CP has higher levels of tangshenoside Ⅰ and sucrose, with noticeably lower cellulose content. These distinctions may be related to their growth conditions, growth years and cultivation techniques. Based on the results of this study, it is recommended to increase polyacetylenes and the content ratio of fructose to sucrose as an indicators to characterize different production methods of CP, in order to guide the high-quality production of CP.

ObjectiveTo compare wild and cultivated Paeoniae Radix Rubra(PRR) in three aspects, including character, microscope, determination of primary and secondary metabolites. MethodSeventeen batches of wild and nine batches of cultivated PRR were collected,their character data were measured by vernier caliper and scales, and their paraffin sections were made by safranin-fixed green dyeing for the observation of microscopic features. The content of ethanol-soluble extracts and total tannin from wild and cultivated PRR was determined by the method of general principle 2201 and 2202 in the 2020 edition of Chinese Pharmacopoeia, the content of polysaccharides was determined by phenol-sulfuric acid method. Anthrone colorimetry was used to determine the content of starch, and Van Soest method of washing fiber was used to determine the content of fiber. The contents of fructose, glucose and sucrose in wild and cultivated PRR were determined by ultra-high performance liquid chromatography evaporative light scattering detection(UPLC-ELSD), and the secondary metabolites(gallic acid, methyl gallate, catechin, oxypaeoniflorin, albiflorin, paeoniflorin, ellagic acid, 1,3,4,6-tetragalloylglucose, galloylpaeoniflorin, 1,2,3,4,6-O-pentagalloylglucose, naringenin, benzoylpaeoniflorin and benzoylalbiflorin) were determined by UPLC. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the data of wild and cultivated PRR, the contribution of different factors to the difference was determined according to the variable importance in the projection(VIP) value>1 and P<0.05. ResultIn term of characters, wild PRR showed the traditional characteristic of Zaopi Fencha, its outer skin was loose and easy to fall off, its surface had longitudinal furrow and wrinkle, but the outer skin of cultivated PRR was not easy to fall off, and its surface was relatively smooth. The radial texture of xylem of wild PRR cross-section was more obvious, showing radial striations, vacuoles and more cracks, while the radial texture of xylem of cultivated PRR cross-section was not obvious, dense and some had cracks. Microscopically, the number of radial vessels arranged in the xylem of wild PRR was more than that of cultivated PRR, the number of calcium oxalate clusters in the phloem and xylem of wild PRR was more than that of cultivated PRR, while the number of starch grains was significantly higher in cultivated PRR. In terms of the content of primary chemical constituents, the contents of polysaccharides and starch of cultivated PRR were significantly higher than those of wild PRR(P<0.05), while the contents of cellulose, lignin, fructose and glucose of wild PRR were significantly higher than those of cultivated PRR(P<0.05). The results of determination of 13 secondary metabolites showed that the contents of paeoniflorin, methyl gallate, catechin and oxypaeoniflorin in wild PRR were significantly higher than those in cultivated PRR(P<0.05), while the contents of albiflorin, gallic acid, ellagic acid, naringenin, benzoylpaeoniflorin and benzoylalbiflorin were significantly lower than those of cultivated PRR(P<0.05). A total of 10 variables contributing to the differentiation between wild and cultivated PRR were screened, including albiflorin, cellulose, benzoylpaeoniflorin, oxypaeoniflorin, naringenin, ellagic acid, starch, lignin, paeoniflorin and total tannins. ConclusionThere are significant differences between wild and cultivated PRR in characters, microscopic characteristics, contents of primary and secondary metabolites. It is suggested that the content ratio of paeoniflorin and albiflorin, the contents of oxypaeoniflorin and cellulose can be used as indicators to characterize production methods of PRR so as to improve the quality standard of PRR. This study can provide reference for the improvement of quality standard of PRR and the guidance of high quality production of PRR.

To realize the non-destructive and rapid origin discrimination of Poria cocos in batches, this study established the P. cocos origin recognition model based on hyperspectral imaging combined with machine learning. P. cocos samples from Anhui, Fujian, Guangxi, Hubei, Hunan, Henan and Yunnan were used as the research objects. Hyperspectral data were collected in the visible and near infrared band(V-band, 410-990 nm) and shortwave infrared band(S-band, 950-2 500 nm). The original spectral data were divided into S-band, V-band and full-band. With the original data(RD) of different bands, multiplicative scatter correction(MSC), standard normal variation(SNV), S-G smoothing(SGS), first derivative(FD), second derivative(SD) and other pretreatments were carried out. Then the data were classified according to three different types of producing areas: province, county and batch. The origin identification model was established by partial least squares discriminant analysis(PLS-DA) and linear support vector machine(LinearSVC). Finally, confusion matrix was employed to evaluate the optimal model, with F1 score as the evaluation standard. The results revealed that the origin identification model established by FD combined with LinearSVC had the highest prediction accuracy in full-band range classified by province, V-band range by county and full-band range by batch, which were 99.28%, 98.55% and 97.45%, respectively, and the overall F1 scores of these three models were 99.16%, 98.59% and 97.58%, respectively, indicating excellent performance of these models. Therefore, hyperspectral imaging combined with LinearSVC can realize the non-destructive, accurate and rapid identification of P. cocos from different producing areas in batches, which is conducive to the directional research and production of P. cocos.

Moutan Cortex(MC) residues produced after the extraction of MC can be re-extracted for active components and used to produce organic fertilizer and animal feed. However, they are currently disposed as domestic waste, which pollutes the environment. This study analyzed the chemical composition of the medicinal material, residues, and residue compost of MC by UPLC-UV-Q-TOF-MS. Furthermore, the nutrient composition of MC residues and the residue compost was analyzed. The results showed that:(1)MC residues had lower content of chemicals than the medicinal material, and content of paeonol, gallic acid, and galloylglucose in MC residues were about 1/3 of that in the medicinal material. The content of chemicals were further reduced after residue composting, and the quantitative compounds were all below the limits of detection.(2)Compared with MC residues, the residue compost showed the total nitrogen, total phosphorus, total potassium, and organic matter content increasing by 122.67%, 31.32%, 120.39%, and 32.06%, respectively. Therefore, we concluded that the MC residues can be used to re-extract active compounds such as paeonol, gallic acid, and galloylglucose. The MC residue compost is a high-quality organic fertilizer containing minimal content of chemicals and can be widely used in the cultivation of Chinese medicinal herbs.
