Abstract:
AIMTo isolate and prepare chemical standards.
METHODSFlavonol 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.
RESULTSTwo 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).
CONCLUSIONCompound I was isolated from this genus for the first time. Compound II is a new compound named as lysimachiin.
