Abstract:
Objective: To study the chemical constituents of Gynostema pentaphyllum. Methods: The chemical constituents were isolated and purified by silica gel, polyamide, and Sephadex LH-20 chromatography. Their structures were elucidated by physicochemical properties and spectral analysis. Results: Seventeen compounds were isolated and identified as dodecanoic acid (1), β-sitosterol (2), 3, 3', 5-trihydroxy-4', 7-dimethoxyflavanone (3), 1-2-benzenediol (4), 3'-O-methyltaxifolin (5), quercetin (6), rhamnetin (7), α-spinasterol-3-O-β-D-glucopyranoside (8), 3, 4-dihydroxy benzoic acid (9), narcissoside (10), L-rhamnosemono-hydrate (11), malonic acid (12), β-ethoxy-rutinoside (13), rutin (14), ombuoside (15), ginsenoside Rb1 (16), and β-daucosterol (17). Conclusion: Compound 1, 3-5, 7, 9, 10, and 12 are obtained from G. pentaphyllum for the first time.
