[Chemical constituents of Begonia evansiana Andr].
Six compounds were isolated from Begonia evansiana. By means of TLC, mp, 1H and 13CNMR, they were idenified as beta-sitosterol, beta-amyrin, daucosterol, stigmasterol, stigmasterol-3-O-beta-D-glucopyranoside and 4', 5', 7-trihydroxy-flavone-6-O-beta-D-glucopyranoside. All the compounds were isolated from this plant for the first time.
