[Studies on chemical constituents from Psychotria straminea].[Pubmed: 26552170]
The chemical consituents from Psychotria straminea were separated and purified by column chromatographies on silica gel, Sephadex LH-20, ODS and RP-HPLC. The strictures of the isolated compounds were identified on the basis of physicochemical properties and spectroscopic analysis, as well as comparisons with the data in literature. Sixteen compounds were isolated and elucidated as tectochrysin (1), apigenin (2), kaempferol (3), luteolin (4), diosmetin (5), quercetin (6), kaempferol-4'-O-methylether (7), rhamnetin (8), 7-hydroxycoumarin (9), 7-methoxycoumarin (10), scopoletin (11), lupeol (12), 30-oxo-lupeol (13), lupenyl acetate (14), α-amyrin (15), and ursolic acid (16). This is the first study on the chemical composition of P. Straminea, and all compounds were isolated from P. straminea for the first time. In addition to compounds 6 and 9, the other compounds were isolated from the genus Psychotria for the first time.
