Abstract:
OBJECTIVETo study the chemical constituents from the bark of Mitragyna rotundifolia.
METHODColumn chromatographic techniques were applied to isolate constituents. A combination of IR, MS and NMR spectroscopy was used to identify structures of constituents.
RESULTSix compounds were isolated from the n-BuOH fraction and their structures were elucidated as quinovic acid-3-O-beta-D-6-deoxy-glucopyranoside, 28-O-beta-D-glucopyranosyl ester (1), quinovic acid-27-O-alpha-L-rhamnopyranosyl ester (2), quinovic acid-3-O-alpha-L-rhamnopyranoside (3), qunovic acid-27-O-beta-D-glucopyranosyl ester (4), quovic acid-3-O-beta-D-6-deoxy-glucopyranoside (5), qunovic acid-27-O-beta-6-deoxy-D-glucopyranosyl ester (6).
CONCLUSIONCompounds 1 - 6 were isolated for the first time from the plant. Compounds 1 - 4 and 6 were isolated for the first time form the genus.
