1Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100094, China.
Aim:
To separate and identify the chemical constituents of the whole plant of Hemistepta lyrata Bunge.
Methods:
Compounds wese separated with chromatography and their chemical strucrures were elucidated with UV, IR, EIMS, FABMS, ESIMS, 1HNMR, 13CNMR HMQC and HMBC spectral methods.
Results:
Five compounds were isolated from the plant. They were identified as apigenin I, apigenin-7-O-beta-D-lutinoside II, acacetin-7-O-beta-D-lutinoside III, astragalin IV, hemislienoside V.
Conclusion:
These compounds were isolated from this plant for the first time, and compound V is a new one.
