STUDY ON CHEMICAL CONSTITUENTS OF HEMISTEPTA LYRATA BUNGE

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-β-D-lutinoside II, acacetin-7-O-β-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.
