Abstract:
OBJECTIVETo investigate the constituents of Ervatamia hainanensis systematically.
METHODVarious chromatographic techniques were applied to isolate and purify the constituents of this plant. The structures were elucidated by spectroscopic analysis.
RESULTEight compounds were obtained, which were identified as alpha-amyrin acetate (1), 11-oxo-alpha-amyrin acetate (2), beta-sitosterol (3), cycloart-23-ene-3beta, 25-diol(4), cycloart-25-ene-3beta, 24-diol (5), 5alpha, 8alpha-epidioxyergosta-6, 22-dien-3beta-ol (6), ibogamin-3-one (7), beta-daucosterol (8).
CONCLUSIONCompounds 1, 2, 4- 7 were isolated from this plant for the first time.
