| Abstract: | AIM: To isolate and prepare chemical standards. METHODS: Flavonol glycoside and rhamnonic acid gamma-lactone were isolated from whole plants of Lysimachia christinae Hance. with 95% ethanol and purified by silica gel column chromatography. UV, IR, MS, 1HNMR, 13CNMR, DEPT, HMQC, HMBC were used for the structural identification. RESULTS: Two compounds were obtained. They were identified as rhamnonic acid gamma-lactone (I) and kaempferol-3-O-alpha-L-rhamnosyl (1-->2)-beta-D-xyloside (II). CONCLUSION: Compound I was isolated from this genus for the first time. Compound II is a new compound named as lysimachiin. |
