Abstract:
Object To study the chemical constituents in the lipophilic portion of Panax notoginseng (Burk.) F H Chen Methods Through monitoring each fraction based on antimicrobial experiment of Staphylococcus aureus Rosenbach, the constituents were isolated on silica gel column chromatography and preparative TLC, and the chemical structures were identified by means of spectral data (IR, MS, 1HNMR, 13 CNMR, DEPT, HMQC, HMBC) Results Three compounds were isolated from its petroleum ether extract and identified as: panaxynol (Ⅰ), panaxydol (Ⅱ), and ? sitosterol (Ⅲ) Conclusion Compounds Ⅰ, Ⅱ having strong antimicrobial activity against S aureus were obtained from this plant with the yields of 0.01% and 0.033%
