Two glycosides from the stem bark of Tetracentron sinense.

Two glycosides, tetracentronsides A and B, were isolated from the stem bark of Tetracentron sinense Oliv., along with ten known compounds, beta-sitosterol, lupeol, betulinic acid, oleanolic acid, vanillic aldehyde, vanillic acid, maslinic acid, huazhongilexin, daucosterol and catechin. On the basis of spectral and chemical evidence, tetracentronside A and B were identified as 3,4,5-trimethoxyphenyl-O-6'-O-vanilloyl-beta-D-glucopyranoside and (8R, 8'R) 9-beta-D-glucopyranosyl dihydrocubebin, respectively.
