To separate and identify the chemical constituents of the whole plant of Hemistepta lyrata Bunge. Compounds wese separated with chromatography and their chemical strucrures were elucidated with UV, IR, EIMS, FABMS, ESIMS, 1HNMR, 13CNMR HMQC and HMBC spectral methods. 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. These compounds were isolated from this plant for the first time, and compound V is a new one.
