Abstract:
Chemical investigation of the plant Tristemma hirtum P. Beauv (Melastomataceae) resulted to the isolation of a new flavonol glycoside named quercetin-7-O-α-D-arabinofuranoside (1), together with nine known compounds including 3′-hexadecanoyl-2′-(9aZ)-tetradecanoyl-glycerol 1′-O-[β-D-galactopyranosyl-(1″ → 6″)-α-D-galactopyranoside] (2), arjunolic acid (3), β-sitosterol-3-O-β-D-glucopyranoside (4), terminolic acid (5), quercetin (6), asiatic acid (7), maslinic acid (8), 1β-O-galloylpedunculagin (9) and 6-hydroxyapigenin 7-O-β-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 spectrometric analysis.
