Gardeniae Fructus, a traditional Chinese medicine, has significant pharmacological activities such as clearing heat and detoxifying, promoting bile secretion and protecting liver injury. It is widely used in clinical practice for treating conditions like fever-induced restlessness, damp-heat jaundice, dysuria with pain, and fire-toxin sores. Gardeniae Fructus has been included in "list of items that are both food and medicine", so it is also used as an ingredient in food and health products. However, recent toxicological studies have shown that Gardeniae Fructus has certain potential hepatotoxicity, and its improper use may pose a risk. Therefore, it is necessary to clarify the dual regulatory effects and their scientific connotations of Gardeniae Fructus on efficacy and toxicity. Based on the current progress in clinical, pharmacological and toxicological researches, this paper will discuss the characteristics and possible mechanisms of the dual effects of efficacy and toxicity of Gardeniae Fructus, and propose thoughts on the rational clinical use and scientific supervision of Gardeniae Fructus.

Baihuasheshecao(Hedyotis diffusa) is a commonly used traditional Chinese medicine derived from the whole herb of H. diffusa and has been widely utilized in folk medicine. It possesses anti-tumor, antibacterial, and anti-inflammatory properties, making it one of the frequently used herbs in TCM clinical practice. However, Shuixiancao(H. corymbosa) and Xianhuaercao(H. tenelliflora), species of the same genus, are often used as substitutes for Baihuasheshecao. To substantiate the medicinal basis of Baihuasheshecao, this study systematically reviewed classical herbal texts and modern literature, examining its nomenclature, botanical origin, harvesting, processing, properties, meridian tropism, pharmacological effects, and clinical applications. The results indicate that Baihuasheshecao was initially recorded as "Shuixiancao" in Preface to the Indexes to the Great Chinese Botany(Zhi Wu Ming Shi Tu Kao). Based on its morphological characteristics and habitat description, it was identified as H. diffusa in the Rubiaceae family. Subsequent records predominantly refer to it as Baihuasheshecao as its official name. In most regions, Baihuasheshecao is recognized as the authentic medicinal material, distinct from Shuixiancao and Xianhuaercao. Baihuasheshecao is harvested in late summer and early autumn, and the dried whole plant, including its roots, is used medicinally. The standard processing method involves cutting. It is known for its effects in clearing heat, removing toxins, reducing swelling and pain, and promoting diuresis to resolve abscesses. Initially, it was mainly used for treating appendicitis, intestinal abscesses, and venomous snake bites, and later, it became a treatment for cancer. The excavation of its clinical value followed a process in which overseas Chinese introduced the herb from Chinese folk medicine to other countries. After its unique anti-cancer effects were recognized abroad, it was reintroduced to China and gradually became a crucial TCM for cancer treatment. The findings of this study help clarify the historical and contemporary uses of Baihuasheshecao, providing literature support and a scientific basis for its rational development and precise clinical application.

OBJECTIVES: To investigate the active ingredients in Hedyotis diffusa-Scutellaria barbata D. Don and the main biological processes and signaling pathways mediating their inhibitory effect on primary hepatocellular carcinoma (HCC). METHODS: The core intersecting genes of HCC and the two drugs were screened from TCMSP, Uniport, Genecards, and String databases using Cytoscape software, and GO and KEGG enrichment analyses of the intersecting genes were conducted. Molecular docking between the active ingredients of the drugs and the core genes was carried out using Pubcham, RCSB and Autoduckto to identify the active ingredients with the highest binding energy, whose inhibitory effect on HepG2 cells was verifies using CCK-8 assay, flow cytometry and Western blotting. RESULTS: TP53 and ESR1 were identified as the core genes of HCC and the two drugs. GO and KEGG analyses showed that the two genes were mainly involved in regulation of apoptotic signaling pathway, cell population proliferation, methane raft, and protein kinase activity, and participated in the signaling pathways of apoptosis, proteoglycans in cancer, PI3K Akt signaling pathway, and hepatitis B. Molecular docking studies showed that the active ingredients of the drugs could be docked with TP53 and ESR1 genes under natural conditions, and ursolic acid had the highest binding energy to ESR1 (-4.98 kcal/mol). The results of CCK-8 assay, flow cytometry and Western blotting all demonstrated significant inhibitory effect of ursolic acid on HepG2 cells. CONCLUSIONS The inhibitory effect of Hedyotis diffusa-scutellariae barbatae on HCC is mediated by multiple active ingredients in the two drugs.

OBJECTIVES: To investigate the therapeutic effects of inulin-type oligosaccharides of Morinda officinalis (IOMO) in a murine model of Streptococcus pneumoniae meningitis (SPM) and explore its possible mechanisms. METHODS: A total of 120 male C57BL/6J mice were randomly assigned into Sham, SPM+Saline, SPM+IOMO (25 mg/kg), and SPM+IOMO (50 mg/kg) groups. After modeling, the mice received daily gavage of saline or IOMO at the indicated doses for 7 consecutive days, and the changes in symptom scores and mortality of the mice were monitored. Brain pathology and neuronal injury of the mice were assessed using HE and Nissl staining, and qRT-PCR was performed to detect mRNA levels of the inflammatory mediators. Brain edema and blood-brain barrier (BBB) permeability of the mice were evaluated by measuring brain water content and Evans blue (EB) staining; Western blotting was used to analyze the expressions of BBB-associated proteins, and flow cytometry was employed to detect IFN‑γ expression level in the infiltrating lymphocytes. Open-field test (OFT) and novel object recognition test (NORT) were conducted to assess learning and memory ability of the mice on day 21 after modeling. RESULTS: IOMO treatment at 50 mg/kg significantly reduced the symptom scores and mortality rate of SPM mice, alleviated brain damage, and downregulated mRNA levels of IL-6, TNF‑α, IL-1β, IL-18, IFN‑γ, iNOS, NLRP3, ASC, caspase-1 and GSDMD in the brain tissue. IOMO treatment also decreased brain water content and EB leakage, upregulated VE-cadherin and occludin expressions, and suppressed AQP4, iNOS, and IFN‑γ levels of the mice. IOMO-treated mice exhibited improved learning and memory compared with the saline-treated mice on day 21 after SPM modeling. CONCLUSIONS IOMO alleviates SPM symptoms, reduces mortality, and mitigates cognitive deficits in mice possibly by suppressing cerebral inflammation and protecting BBB functions.

OBJECTIVE: To evaluate the apoptosis and cycle arrest effects of Oldenlandia diffusa flavonoids on human gastric cancer cells, determine the action mechanisms in association with the mitochondrial dependent signal transduction pathway that controls production of reactive oxygen species (ROS), and evaluate the pharmacodynamics of a mouse xenotransplantation model to provide a reference for the use of flavonoids in prevention and treatment of gastric cancer. METHODS: Flavonoids were extracted by an enzymatic-ultrasonic assisted method and purified with D-101 resin. Bioactive components were characterized by high-performance liquid chromatography. Cell lines MKN-45, AGS, and GES-1 were treated with different concentrations of flavonoids (64, 96, 128, 160 µg/mL). The effect of flavonoids on cell viability was evaluated by MTT method, and cell nuclear morphology was observed by Hoechst staining. The apoptosis rate and cell cycle phases were measured by flow cytometry, the production of ROS was detected by laser confocal microscope, the mitochondrial membrane potential (MMP) were observed by fluorescence microscope, and the expression of apoptotic proteins related to activation of mitochondrial pathway were measured by immunoblotting. MKN-45 cells were transplanted into BALB/c nude mice to establish a xenograft tumor model. Hematoxylin and eosin staining was used to reveal the subcutaneous tumor tissue. The tumor volume and tumor weight were measured, the expression levels of proliferation markers proliferating cell nuclear antigen (PCNA) and Ki-67 were detected by immunohistochemistry, and the expression levels of CA72-4 were measured by enzyme linked immunosorbent assay. RESULTS: Oldenlandia diffusa flavonoids inhibited proliferation of MKN-45 and AGS human gastric cancer cells, arrested the cell cycle in G₁/S phase, induced accumulation of ROS in the process of apoptosis, and altered MMP. In addition, flavonoids increased Apaf-1, Cleaved-Caspase-3, and Bax, and decreased Cyclin A, Cdk2, Bcl-2, Pro-Caspase-9, and Mitochondrial Cytochrome C (P<0.05). The MKN-45 cell mouse xenotransplantation model further clarified the growth inhibitory effect of flavonoids towards tumors. The expression levels of PCNA and Ki-67 decreased in each flavonoid dose group, the expression level of CA72-4 decreased (P<0.05). CONCLUSION Flavonoids derived from Oldenlandia diffusa can inhibit proliferation and induce apoptosis of human gastric cancer cells by activating the mitochondrial controlled signal transduction pathway.

Rheumatoid arthritis(RA), a chronic autoimmune disease, is featured by persistent joint inflammation. The development of RA is associated with the disturbance of endogenous metabolites and intestinal microbiota. Gardeniae Fructus(GF), one of the commonly used medicinal food in China, is usually prescribed for the prevention and treatment of jaundice, inflammation, ache, fever, and skin ulcers. GF exerts an effect on ameliorating RA, the mechanism of which remains to be studied. In this study, ultra-perfor-mance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)-based serum non-target metabolomics and 16S rDNA high-throughput sequencing were employed to elucidate the mechanism of GF in ameliorating RA induced by complete Freund's adjuvant in rats. The results showed that GF alleviated the pathological conditions in adjuvant arthritis(AA) rats. The low-and high-dose GF lo-wered the serum levels of interleukin(IL)-6, tumor necrosis factor-α(TNF-α), IL-1β, and prostaglandin E2 in the rats(P<0.05, P<0.01). Pathways involved in metabolomics were mainly α-linolenic acid metabolism and glycerophospholipid metabolism. The results of 16S rDNA sequencing showed that the Streptococcus, Facklamia, Klebsiella, Enterococcus, and Kosakonia were the critical gut microorganisms for GF to treat AA in rats. Spearman correlation analysis showed that the three differential metabolites PE-NMe[18:1(9Z)/20:0], PC[20:1(11Z)/18:3(6Z,9Z,12Z)], and PC[20:0/18:4(6Z,9Z,12Z,15Z)] were correlated with the differential bacteria. In conclusion, GF may ameliorate RA by regulating the composition of intestinal microbiota, α-linolenic acid metabolism, and glycerophospholipid metabolism. The findings provide new ideas and data for elucidating the mechanism of GF in relieving RA.

The aim of this study was to compare crocins in the fruit of Gardenia jasminoides and Gardenia jasminoides var. radicans. Acchrom XCharge C_(18) column(4.6 mm×250 mm, 5 μm) was used for separation, with mobile phase of acetonitrile and 0.1% formic acid for gradient elution. The detection wavelength was set at 440 nm with a flow rate of 1.0 mL·min~(-1), and the column temperature was 30 ℃. The high performance liquid chromatography(HPLC) fingerprint of crocin in Gardenia species was established by testing 20 batches of G. jasminoides and 8 batches of G. jasminoides var. radicans samples from different sources, and UHPLC-ESI-Orbitrap-MS/MS technology and reference substances were used to predict and identify the common peaks. The results showed that 20 common chromatographic peaks from the samples were selected and the structures of 16 common peaks were predicted by mass spectrum. Four common peaks(crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ) were identified by the comparison with reference substances. The content of crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ was determined simultaneously under the same chromatographic condition, and both the system suitability and the methodological investigation results met the requirements of content determination. The relative similarity of HPLC fingerprint of 28 samples to the reference fingerprint was above 0.98. The results of cluster analysis(CA) showed that G. jasminoides and G. jasminoides var. radicans were separately grouped into one group. In the 20 batches of G. jasminoides, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 3.58-9.58, 0.230-1.452, 0.014 5-0.135, and 0.301-1.12 mg·g~(-1), respectively, and the total content was between 4.12-12.25 mg·g~(-1). In the 8 batches of G. jasminoides var. radicans, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 5.84-11.48, 0.308-0.898, 0.010 6-0.025 5, and 0.675-1.34 mg·g~(-1), respectively, and the total content was between 6.97-13.72 mg·g~(-1). The existing results showed that there is a certain similarity between G. jasminoides and G. jasminoides var. radicans in the composition of crocin, which needs further proved by more batches of samples. The method established in this paper provides references for the quality control of G. jasminoides, G. jasminoides var. radicans, and related products.

This study aimed to explore the correlation of the content of 15 non-crocin components of Gardeniae Fructus with its external properties(shape and color). The fruit shape was quantified according to the length/diameter measured by ruler and vernier calliper and the chromaticity values L~*, a~*, b~*, and ΔE~* of all samples were determined by chroma meter. Chromatographic separation was conducted on a Welch Ultimate XB C_(18) column(4.6 mm×250 mm, 5 μm) under gradient elution with acetonitrile solution(A) and 0.1% formic acid aqueous solution(B) as the mobile phase at a flow rate of 1.0 mL·min~(-1). The column temperature was 30 ℃ and the detection wavelength was 238 nm. The high-performance liquid chromatography(HPLC) method was established for simultaneous determination of the content of eight iridoid glycosides, six phenolic acids, and one flavonoid in 21 batches of Gardeniae Fructus samples. The correlation of the content of the 15 components with shapes and chromaticity values in each sample was analyzed by multivariate statistical analysis. According to the circulation situation and traditional experience, 21 batches of Gardeniae Fructus samples were divided into three categories, namely 14 batches of Jiangxi products(small and round, red and yellow), 4 batches of Fujian products(oval, red) and 3 batches of Shuizhizi(Gardenia jasminoides, longest, reddest). The Gardeniae Fructus samples were sequenced as Jiangxi products(1.71) < Fujian products(1.99) < Shuizhizi(2.55) in terms of the length/diameter average, Jiangxi products(17.7) < Fujian products(19.7) ≈ Shuizhizi(19.6) in terms of average value of a~*(red and green), Jiangxi products(24.4) > Fujian products(19.2) ≈ Shuizhizi(19.3) in terms of b~*(yellow and blue), and Jiangxi products(49.8) > Fujian products(48.0) ≈ Shuizhizi(47.8) in terms of L~*(brightness). The total content of the 15 components, 8 iridoid glycosides, 6 phenolic acids, and rutin in Jiangxi products was in the ranges of 65.53-99.64, 52.15-89.16, 6.10-11.83, and 0.145-1.81 mg·g~(-1), respectively. The total amount of the 15 components, 8 iridoid glycosides, 6 phenolic acids, and rutin in Fujian products was in the ranges of 69.33-94.35, 63.52-85.19, 5.39-8.41, and 0.333-0.757 mg·g~(-1), respectively. In Shuizhizi, the total content of the 15 components, 8 iridoid glycosides, 6 phenolic acids, and rutin was in the ranges of 77.35-85.98, 68.69-76.56, 7.30-9.05, and 0.368-0.697 mg·g~(-1), respectively. Pearson correlation analysis revealed that Gardeniae Fructus with leaner and longer fruit shape possessed lower content of total phenolic acids(the sum of the six phenolic acids) and rutin, but the correlation with iridoid glycosides was not high. Additionally, the higher content of total phenolic acids and rutin denoted the yellow coloration of Gardeniae Fructus, and the higher content of cryptochlorogenic acid, chlorogenic acid, and rutin meant the brighter color of Gardeniae Fructus. However, the higher content of geniposide and neochlorogenic acid and the lower content of deacetyl asperulosidic acid methyl ester led to the red coloration of Gardeniae Fructus. The results indicated that the morphological characters of Gardeniae Fructus were closely related to its chemical components. The more round shape and the yellower color reflected the higher content of phenolic acids and flavonoid, and Gardeniae Fructus with redder color had higher content of geniposide. OPLA-DA showed that the length/diameter and the content of six iridoid glycosides(gardoside, shanzhiside, gardenoside, genipin 1-gentiobioside, 6β-hydroxy geniposide, and deacetyl asperulosidic acid methyl ester), two phenolic acids(neochlorogenic acid and cryptochlorogenic acid) and rutin could be used as markers to distinguish three types of samples. This study provided experimental data for the scientific connotation of "quality evaluation through morphological identification" of Gardeniae Fructus.
