METHODS
Compounds were isolated by silica gel, MCI, Sephadex LH-20 and Rp-18 column chromatography, and purified by recrystallization. Their structures were elucidated by spectral analysis and other methods.
RESULTS
Six compounds were isolated and identified as friedelin (1) epi-friedelan-3-ol (2), heneicosanoic acid (3), beta-sitosterol (4), Propyl palmitate (5), eatechin (6), respectively.
CONCLUSIONS
Compounds 1-3, 5, 6 are isolated from Grewia genus for the first time and compounds 4 is isolated from Grewia biloba for the first time.
