【Abstract】 Aim To isolate and prepare chemical standards. Methods Flavonol glycoside and rhamnonic acid γ lactone were isolated from whole plants of Lysimachia christinae Hance. with 95% ethanol and purified by silica gel column chromatography. UV, IR, MS, 1HNMR, 13 CNMR, DEPT, HMQC, HMBC were used for the structural identification. Results Two compounds were obtained. They were identified as rhamnonic acid γ lactone (I) and kaempferol 3 O α L rhamnosyl (1→2) β D xyloside (II). Conclusion Compound I was isolated from this genus for the first time. Compound II is a new compound named as lysimachiin.更多还原
