Object To investigate the saccharide changes of Radix Rehmanniae when being processed. Methods The fresh roots were torrefied at 65 ℃ and sampled at 0,1, and 6 d. The samples and 4 h steamed slices of those dried roots were extracted with hot water respectively. The extracts were subjected to HPLC analysis, Sugar pak 1 column at 80 ℃,with water as the mobile phase at 0 7 mL/min and detected by RID. Results There are three principal components in the fresh roots, i.e. stachyose (11%-15%), sucrose (0 30%-0 92%), and catalpol (0 27%-0 88%). In the processing of the fresh roots, the HPLC chromatorams of the extracts differed to each other remarkbly. On the chromatogram of roots torrefied for 1 d, one distinct monosaccharide peak displayed at 10 2 min, which is likely to be galactose, and it become prominent in the dried roots together with raffinose. In steamed ones, the peaks of fructose and glucose became outstanding. Conclusion According to the HPLC chromatograms, the degalacto sylation of stachyose may take place during torrifying, while defructosylation during steaming. One of the principal purposes of the processing may be for stachyose degradation for its flatulence causing character.

Quality variation and ecotype classification of Chinese herbal medicine are important scientific problems in Daodi herbal medicine research. The diversity of natural environmental conditions has led to form unique multi-Daodi, multi-product areas that produce particular Chinese herbal medicine. China is one of three big American ginseng (Panax quinquefolium L.) producing areas worldwide, with over 300 years of application and 40 years of cultivation history. Long-term production practice has led to the formation of three big advocate produce areas in China: Northeast province, Beijing and Shandong. P. quinquefolium L. grown under certain environmental conditions will develop long-term adaptations that will lead to more stable strains (different ecotypes). P. quinquefolium L., can vary greatly in quality; however, the ecological mechanisms causing this variation are still unclear. Root samples were collected from four-year-old cultivated P. quinquefolium L. plants in the three major genuine (Daodi) American ginseng-producing areas of Northeast province, Beijing and Shandong province, China. Ultra-performance liquid chromatography was used to analyze the contents of eight ginsenosides (Rg1, Re, Rb1, Rb2, Rb3, Rc, Rd, Rg2). Data for nine ecological factors, including temperature, moisture and sunlight, were obtained from the ecological database of Geographic Information System for Traditional Chinese Medicine. Soil samples from the sampling sites were collected. Effective boron and iron, available nitrogen and potassium, as well as other trace elements and soil nutrients, were determined by conventional soil physicochemical property assay methods. Analytical methods of biostatistics and numerical taxonomy were used to divide ecotypes of the three main Panax quinquefolium L. producing areas in China based on ginsenoside content, climate, soil and other ecological factors. To our knowledge, this is the first time that ecological division of P. quinquefolium L. producing areas in China has ever been conducted. The results show that there are two chemoecotypes of P. quinquefolium L. in China: ginsenoside Rb1-Re from outside Shanhaiguan, and ginsenoside Rg2-Rd from inside Shanhaiguan. Similarly, there are two types of climatic characteristics: inside Shanhaiguan (Beijing, Shandong) and outside Shanhaiguan (Northeast). This suggests that the formation and differentiation of chemoecotypes of P. quinquefolium L. is closely related to variability of the climatic and geographical environment. Additionally, ecological variation of the three main producing areas, characteristics of two climatic ecotypes, and soil characteristics are also discussed and summarized. These results provide experimental scientific evidence of the quality variation and ecological adaptation of P. quinquefolium L. from different producing areas. They also deepen our understanding of the biological nature of Daodi P. quinquefolium L. formation, and offer novel research models for other multi-origin, multi-Daodi Chinese herbal medicines ecotypes. In addition, the results demonstrate the critical need for improving quality, appropriate ecological regionalization and promoting industrialized development of P. quinquefolium L.

Ultrafine powder and cell wall-broken powder of herbal medicine lack of the morphological characters and microscopic identification features. This makes it hard to identify herb's authenticity with traditional methods. We tested ITS2 sequence as DNA barcode in identification of herbal medicine in ultrafine powder and cell wall-broken powder in this study. We extracted genomic DNAs of 93 samples of 31 representative herbal medicines (28 species), which include whole plant, roots and bulbs, stems, leaves, flowers, fruits and seeds. The ITS2 sequences were amplified and sequenced bidirectionally. The ITS2 sequences were identified using Basic Local Alignment Search Tool (BLAST) method in the GenBank database and DNA barcoding system to identify the herbal medicine. The genetic distance was analyzed using the Kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic tree was constructed using MEGA 6.0. The results showed that DNA can be extracted successfully from 93 samples and high quality ITS2 sequences can be amplified. All 31 herbal medicines can get correct identification via BLAST method. The ITS2 sequences of raw material medicines, ultrafine powder and cell wall-broken powder have same sequence in 26 herbal medicines, while the ITS2 sequences in other 5 herbal medicines exhibited variation. The maximum intraspecific genetic-distances of each species were all less than the minimum interspecific genetic distances. ITS2 sequences of each species are all converged to their standard DNA barcodes using NJ method. Therefore, using ITS2 barcode can accurately and effectively distinguish ultrafine powder and cell wall-broken powder of herbal medicine. It provides a new molecular method to identify ultrafine powder and cell wall-broken powder of herbal medicine in the quality control and market supervision.

Object To develop a method of multiplying virus free clonal seedlings of CV.85 5 of Rehmannia glutinosa (Gaert.) Libosch. ex Fisch. et Mey.. Methods The leaf cut segments with or without tips of plantlets were grown in different media (mg/L) (1.MS+BA 0.5; 2 MS+BA 0.5+NAA 0.02;3 MS+BA 0.5+NAA 0.02+GA 3 0.1; 4 1/2 MS+BA 0.1; 5 1/2 MS+BA 0.1+GA 3 0.1; 6.1/2 MS+GA 3 0.1) to select a suitable medium, and the height and the numbers of newly formed leaves and roots were recorded 30 days later. To screen out a favorable condition, similar segments were transferred to No.2 medium at different temperatures in different illuminations, and the height together with the leaf number and the fresh weight of the plantlets was recorded.Results In the former three media, the segments with tips were flourishing and one to three axillary buds were formed at its basal stem; while in those without tips almost every axillary bud developed with the main tip length 0.5~1.5 cm. In the later three media, thd elongation of the segments was usually overstimulated, and the slim plantlets with fewer leaves and more roots formed. When the segments cultured in No.2 medium, all records at 28 ℃ were higher than those at 23 ℃ in the same illuminations. But the leaf size and the height of the plantlets were inversely proportional to the intensity of illumination at the same temperature. In addition, antagonism between BA and GA 3 was found.Conclusion No.2 medium is more suitable for the multiplication of the virus free seedlings of 85 5 when cultured at 28 ℃ in the illumination of 1 000~2 000 lx.

ObjectiveTo explore the interaction between bruceoside B and gut microbiota and the inhibitory activity of its metabolites on human lung cancer A549 cells, and to explore the value of bruceoside B in the treatment of non-small cell lung cancer(NSCLC). MethodBruceoside B was co-incubated with the human gut microbiota under anoxic conditions in vitro, and ultra high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to analyze the metabolic transformation products. Cell counting kit-8(CCK-8) assay was performed to determine the effects of bruceoside B and its metabolites on the proliferation of human lung cancer A549 cells and the half inhibitory concentration(IC50) was calculated. Five healthy male rats were gavaged with bruceoside B(2 mg·kg-1) for 7 days after adaptive feeding. The feces of rats were collected before and after administration. 16S rRNA sequencing was used to assess gut microbiota. ResultBruceoside B was mainly metabolized to brusatol by human gut microbiota, the IC50 of bruceoside B and the conversion product to A549 cells were 1 755.50, 19.57 μmol·L-1, respectively, and the conversion product had a better activity at inhibiting A549 cells proliferation than bruceoside B. Additionally, The results of intestinal flora analysis showed no significant differences in α diversity and β diversity of gut microbiota after administration. In terms of species abundance, at the phylum level, bruceoside B decreased the relative abundance of Actinobacteriota and Proteobacteria, increased the relative abundance of Firmicutes, Patescibacteria and Cyanobacteria. At the genus level, bruceoside B decreased the relative abundance of Staphylococcus, Aerococcus and Psychrobacter, increased the relative abundance of Romboutsia, Lactobacillus, Clostridium sensu stricto 1, Norank-f-norank-o-Clostridia-UCG-014, Turicibacter, Allobaculum and Candidatus Saccharimonas. The results of functional prediction showed that the gut microbiota functional compositions were relatively stable. ConclusionBruceoside B can be deglycosylated by intestinal flora and converted into brusatol, with a significant increase in antitumor activity. The administration of bruceoside B will not cause significant changes in the structure and function of the intestinal flora, resulting in intestinal microecological balance disorders, and the administration appears to be beneficial to the intestinal flora of NSCLC patients.

Coronary heart disease (CHD) with atherosclerosis is a common chronic disease worldwide, and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang (CLMT), first mentioned in the Shang Han Lun (《伤寒论》), is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit, with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways, including regulating related signaling pathways, inhibiting the expression of inflammatory factors, improving oxidative stress damage, modulating neurotransmitter levels, suppressing the hypothalamic-pituitary-adrenal axis, promoting mobilization of mesenchymal stem cells from the bone marrow, and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression, effectively reduces negative emotions, improves traditional Chinese medicine (TCM) syndrome scores, and decreases levels of inflammatory factors. Furthermore, it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, PubMed, and other databases in the past 15 years, in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.
