ABSTRACT
<p><b>AIM</b>To isolate and prepare chemical standards.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>Compound I was isolated from this genus for the first time. Compound II is a new compound named as lysimachiin.</p>
