[Isolation and structure identification of flavonol glycoside from Lysimachia christinae Hance].
OBJECTIVE
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).


CONCLUSIONS
Compound I was isolated from this genus for the first time. Compound II is a new compound named as lysimachiin.
