The chem. constituents of Gynostema pentaphyllum were studied. The chem. constituents were isolated and purified by silica gel, polyamide, and Sephadex LH-20 chromatog. Their structures were elucidated by physicochem. properties and spectral anal. Seventeen compounds were isolated and identified as dodecanoic acid (1), β-sitosterol (2), 3,3′,5-trihydroxy-4′,7-dimethoxyflavone (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-rhamnosemonohydrate (11), malonic acid (12), β-ethoxy-rutinoside (13), rutin (14), ombuoside (15), ginsenoside Rb1 (16), and β-daucosterol (17). Compound 1,3-5,7,9,10, and 12 are obtained from G. pentaphyllum for the first time. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0Computed Properties of C6H14O6).
(2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Computed Properties of C6H14O6
