Chemical constituents of Vernonia parishii Hook f. and their biological activities

Abstract

Thefirst investigation pertaining to chemical constituents of the dichloromethane extract from V. parishii leaves found nine known compounds, consisting ofstigmasterol (58), α-amyrin acetate (9), lupeol acetate (59), lupeol palmitate (60), lupenone (61), lupeol (41) α-amyrin (13), hentriacontane (62), and palmitic acid (63). All isolated compounds were elucidated and identified their structures on the basis of spectrum and physical properties. These were referred to the data from spectroscopictechniques such as 1H NMR and 13C NMR, COSY, DEPT, HMQC, HMBC, mass spectrometry, and IR spectroscopy, which were compared with previous literatures.
