RESUMEN
Aim To explore the main active ingredients of Tripterygium wilfordii and the mechanism in treat-ment of breast cancer based on network pharmacology.Methods The active components and targets of Tripterygii Wilfordii were searched by TCMSP.GeneCard database was used to screen the potential targets of Tripterygii Wilfordii in treatment of breast cancer.The two were matched to obtain the core components and targets of Tripterygii Wilfordii.Cytoscape3.6.0 and AutoDock Vina were used to draw the drug-target network diagram, and GO enrichment analysis, KEGG pathway enrichment analysis, and molecular docking between the core target and the components were carried out.CCK8 and qPCR were used to verify the effect of optimal core component tripterine on breast cancer cells.Results Seven kinds of active anti-breast cancer components and twenty-five core therapeutic targets of Tripterygii Wilfordii were obtained.Tripterine, which significantly inhibited the growth of breast cancer cells, was the most valuable component of Tripterygii Wilfordii for breast cancer.QPCR results showed that tripterine decreased the expression of core therapeutic targets.Conclusions The effectiveness of Tripterygii Wilfordii has multiple pathways, and tripterine may play an important role in treatment of breast cancer.
RESUMEN
Objective To establish an HPLC method for determination of triptoquinone B in Radix Folium Seu Flos Tripterygii Wilfordii(RFFTW) and its tablets.Methods An external method with HiQ siL KYA-C_(18)(250 mm?4.6 mm,5 ?m) column as fixed phase and methanol-1% acetic acid solution((66∶)34) as mobile phase was adopted.The detective wave length was 254 nm and the flow rate was 1.0 mL/min.Results The linearity range was 6.62—105.9 ?g/mL(r=0.999 9),the average recovery of T.wilfordii from Hunan Province was 97.78%,RSD was 1.09%(n=9),and the average recovery of tablet of T.hypoglaucum was 99.83%,RSD was 1.76%(n=9).Conclusion The method is accurate and sensitive.It is adoptable for quantitative analysis of triptoquinone B in RFFTW and its tablets.
RESUMEN
Objective: To determine the condition of drying process for Radix Tripterygii Wilfordii extract. Methods: Under different dying temperature and time, both triptolide and triptophenolide extracted from extract of Radix Tripterygii Wilfordii were measured. Results: After Radix Tripterygii Wilfordi extract was dried for 48 hours at 80 ?C , loss of triptophenolide and triptolide was relatively low, but after dried more than 48 hours at 100 ?C , the content of triptophenolide and triptolide reduced by 15.0%～30.0%. Conclusion: Drying temperature for Radix Tripteryqii Wilfordii extract should be controlled under 80 ?C .
