摘要	Two new 27-nor-triterpene glycosides, pyrocincholic acid 3 beta-O-beta-D-glucopyranosyl-(1 -> 4)beta-D-quinovopyranosyl-28-O-beta-D-glucopyranoside (Metatrichoside A, 1), pyrocincholic acid 3 beta-O-beta-D-glucopyranosyl-(1 -> 4)-beta-D-quinovopyranosyl-28-O-beta-D-glucopyranosyl-(1 -> 6)-beta-Dglucopyranoside (Metatrichoside B, 2), together with pyrocincholic acid 3 beta-O-beta-D-quinovopyranosyl-28-O-beta-D-glucopyranoside (3), pyrocincholic acid 3 beta-O-beta-D-quinovopyranosyl-28-O-beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranoside (4), quinovic acid 3 beta-O-beta-D-quinovopyranoside (5), quinovic acid 3 beta-O-beta-D-quinovopyranosyl-28-O-beta-D-glucopyranoside (6), quinovic acid 3 beta-O-beta-D-glucopyranoside (7) and quinovic acid 3 beta-O-beta-D-glueopyranosyl-28-O-beta-D-glucopyranoside (8) were isolated from the barks of Metadina trichotoma. Their structures were mainly determined by mass spectrometric and 1D and 2D NMR spectroscopic methods. Compound 5 and 6 showed cytotoxic activities towards the A549 non-small-cell lung cancer cell line (IC50 = 8.43 and 6.06 mu m), and the methanol extract inhibited the activity of cathepsin B with an IC50 value of 0.77 mu g mL(-1).
