Patrinia villosa, regarding its functions in clearing heat and detoxification and eliminating carbuncles and pus, is widely used as a traditional medicinal herb that contains rich nutrition and substances such as various amino acids, vitamins, and soluble su-gar, and it is also an edible wild herb in Chinese folk tradition for 2 000 years. In 1973, Japanese scholars firstly separated three iridoids from Japanese P. villosa, and by 2021, chemical components such as flavonoids, iridoids, organic acids, triterpenoids, phenylpropanoids, and steroids have been found, which have multiple pharmacological effects, including antioxidant, antitumor, anti-diarrhea, antibacterial, sedative, and liver protection capabilities. Studies indicate that flavonoids, saponins, phenylpropanoids, and triterpenoids in P. villosa are vital substances for its pharmacological activities. However, the quality of this medicinal material cannot be controlled due to the unclear records in ancient books in the past dynasties and different drug use habits in different places, and thus its circulation is chaotic. At present, researchers have used flavonoids, organic acids, phenylpropanoids, triterpenoid saponins, and other compounds to conduct studies in this regard. Therefore, on the basis of the existing literature resources, we comprehensively summarize the chemical constituents, pharmacological activities, and quality control of P. villosa to further provide a reference for the safety and effectiveness of clinical drug use and lay a foundation for the follow-up experimental research.

OBJECTIVE:
To explore the effect of dichloromethane extraction phase of ethanol extract from stem of Patrinia scabiosaefolia Fisch.(DPSS) on proliferation and differentiation of K562 cells and its related mechanism.
METHODS:
MTT assay was used to detect the effects of DPSS at 0, 25, 50, 100 and 200 μg/ml on the proliferation of K562 cells at 24, 48 and 72 hours. Flow cytometry was used to analyze the changes of cell cycle and apoptosis at 24 and 48 hours. Wright-Giemsa staining was used to observe the morphological changes of K562 cells. The cell surface antigens CD33 and CD11b were detected by flow cytometry.
RESULTS:
The proliferation of K562 cells treated with different concentrations of DPSS was inhibited in a time-dose dependent manner (r=-0.96). Cell cycle analysis showed that with the increase of DPSS concentration, cells in G2/M phase increased (r=0.88), and cells were blocked in G2/M phase. Flow cytometry results showed that with the apoptosis rate of K562 cells was the highest when treated with 200 μg/ml DPSS for 48 h. Morphological observation showed that the K562 cell body increased, the amount of cytoplasm increased, the ratio of nucleus to cytoplasm decreased, and the nuclear chromatin was rough after DPSS treatment. Cell differentiation antigen, CD33 and CD11b, were positively expressed after treated with DPSS.
CONCLUSION
DPSS can induce apoptosis through cell cycle arrest, inhibit the proliferation of K562 cells, and induce K562 cells to differentiate into monocytes, which has a potential anti-leukemia effect.

OBJECTIVETo study the chemical composition, anticancer, anti-neuroinflflammatory, and antioxidant activities of the essential oil of Patrinia scabiosaefolia (EO-PS).
METHODSPatrinia scabiosaefolia was analyzed by gas chromatography-mass spectrometry. Eight human carcinoma cell lines, including SGC-7901, AGS, HepG2, HT-29, HCT-8, 5-FU/HCT-8, HeLa, and MDA-MB-231, were assessed by methylthiazolyldiphenyltetrazolium bromide (MTT) assay. Anti-neuroinflflammatory activity was assessed by production of interleukin (IL)-1β and IL-6 induced by lipopolysaccharide in BV-2 cells (microglia from mice). The antioxidant activity was evaluated with a 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay.
RESULTSForty-four components, representing 83.919% of the total oil, were identifified in the EO-PS. The major constituents were caryophyllene oxide (12.802%), caryophyllene (6.909%), α-caryophyllene (2.927%), β-damascenone (3.435%), calarene (5.621%), and phenol (3.044%). The MTT assay showed that the EO-PS exhibited significant dose-dependent growth inhibition in the 50-200 μg/mL dilution range. The EO-PS exhibited a dose-dependent scavenging activity against the DPPH radical, with an half of maximal inhibitory concentration 1.455 mg/mL.
CONCLUSIONSThe EO-PS possesses a wide range of antitumor, anti-neuroinflflammatory and antioxidant activities, suggesting that it may be a good candidate for further investigations of new bioactive substances.

OBJECTIVETo study the erythrocyte immuno-regulatory effect of Patrinia scabra Bunge extracts extracted by macroporous adsorptive resins in tumor bearing mice.
METHODSPatrinia scabra Bunge was extracted by macroporous adsorptive resins, and the amount of polysaccharides and saponins in the extract were determined. Mice bearing S180 tumor were treated with the extract and their survival prolongation rate, erythrocyte rosette formation rates of C3b receptor (ERR-CR), immune complex (ERR-IC) and tumor cell (ERR-TC), as well as the CD35 and CD44s were observed.
RESULTSPolysaccharide content was 21.4%, saponin 41.8% in the extract. As compared with the model group, the survival rate was increased, the erythrocyte immune function was improved (showed increase of ERR-CR and ERR-TC, decrease of ERR-IC), and the amount of CD35 and CD44s in red blood cell membrane increased in mice after being treated with the extract (P < 0.05 or P < 0.01).
CONCLUSIONExtract of Patrinia scabra Bunge extracted by macroporous adsorptive resins can regulate the erythrocyte immune function to a certain extent.

OBJECTIVE:
To investigate the effects of ethanol extract of Patrinia scabiosaefolia (EEPS) on chemo-resistance of colorectal cancer cells (CRC) and explore the possible molecular mechanisms.
METHODS:
5-fluorouracil (5-FU)-resistant human colorectal carcinoma cell line (HCT-8/5-FU) and its parental cells HCT-8 were treated with EEPS (0, 0.25, 0.50, 1 or 2 mg/mL), or 5-FU (0, 100, 200, 400, 800 or 1600 μmol/L). The 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay was performed to evaluate the cell viability. Cell density was observed by phase-contrast microscope, cell counting and colony formation assay were used to determine the cell proliferation of HCT-8/5-FU cells treated with 0, 0.5, 1 or 2 mg/mL EEPS. Cell apoptosis was determined by Hoechst staining. Western-blot was performed to detect the phosphorylation of AKT as well as the protein expression level of B-cell CLL/lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax).
RESULTS:
Compared with HCT-8 cells, MTT assay results indicated that HCT-8/5-FU cells were resistant to 5-FU treatment (P<0.05), and sensitive to EEPS treatment (P>0.05). Moreover, compared with untreated HCT-8/5-FU cells, 1 and 2 mg/mL of EEPS treatment significantly reduced cell density, cell number, inhibited cell survival (P<0.05), and induced apoptosis in HCT-8/5-FU cells. Furthermore, 1 and 2 mg/mL of EEPS significantly decreased the phosphorylation level of p-AKT and Bcl-2 protein expression, and increased the expression of Bax protein (P<0.05).
CONCLUSION
EEPS is a promising therapeutic agent that may overcome chemo-resistance in cancer cells, likely through suppression of the AKT pathway and promotion of cancer cell apoptosis.
