Abstract:
Objective To investigate the chemical constituents of Hemistepta lyrata. Methods The entire plants were first extracted by 95% of ethanol, then extracted by petroleum ether, chloroform, ethyl acetate and n-butanol, respectively. The residue from n-butanol extraction was purified on silica gel column chromatograph and Sephadex LH-20 column, respectively. Structures of the purified compounds were elucidated by MS and NMR. Results Four compounds were isolated and identified as syringin （ 1 ）, salicin （ 2 ）, allantoin （3） and chlorogenic acid （4）. Conclusion Compounds 1 to 4 were isolated from this plant for the first time.[著者文摘]
