A New Flavonol Glycoside from Tristemma hirtum (Melastomataceae)

A New Flavonol Glycoside from Tristemma hirtum (Melastomataceae)

Chemical investigation of the plant Tristemma hirtum P. Beauv (Melastomataceae) resulted to the isolation of a new flavonol glycoside named quercetin-7-O-a-D-arabinofuranoside (1), together with nine known compounds including 3'-hexadecanoyl-2'-(9aZ)-tetradecanoyl-glycerol 1'-O-[b-D-g...

Description
Summary:Chemical investigation of the plant Tristemma hirtum P. Beauv (Melastomataceae) resulted to the isolation of a new flavonol glycoside named quercetin-7-O-a-D-arabinofuranoside (1), together with nine known compounds including 3'-hexadecanoyl-2'-(9aZ)-tetradecanoyl-glycerol 1'-O-[b-D-galactopyranosyl-(1'' → 6'')-a-D-galactopyranoside] (2), arjunolic acid (3), b-sitosterol-3-O-b-D-glucopyranoside (4), terminolic acid (5), quercetin (6), asiatic acid (7), maslinic acid (8), 1b-O-galloylpedunculagin (9) and 6-hydroxyapigenin 7-O-b-D-glucopyranoside (10) from the methanol extract using normal and reversed phase column chromatography. The structures of these compounds were determined by comprehensive interpretation of their spectral data mainly including 1D- 2D-NMR (1H-1H COSY, HSQC, and HMBC) spectroscopic and ESI-TOF-MS mass spectro- metric analysis.
