Investigation of liposoluble constituents from pothos chinensis (Raf.) Merr / 中国药学杂志

ABSTRACT

OBJECTIVE: To investigate the liposoluble constituents from the herb of Pothos chinensis (Raf.) Merr. of Araceae. METHODS: The compounds were isolated and purified by silica gel, Sephadex LH -20, semi-preparative HPLC and recrystallization methods. Their structures were identified on the basis of spectral analysis, physicochemical characteristics and comparison of their spectral data with those in the literature. RESULTS: Seventeen compounds were isolated and identified respectively as honokiol(1), hinokinin(2), racemosol(3), 24-propylcholest-7-en-3-ol(4), β-sitosterol(5), daucosterol (6), hentriacontane(7), palmitic acid (8), oleic acid(9), linoleic acid(10), 9, 12, 15-ocatadecatrienoic acid(11), 13-phenyltridecanoic acid(12), 13-(3', 4'-methyl -enedioxyphenyl)-tridecanoic acid(13), 1-monostearin(14), 1-monopalmitin(15), benzoic acid(16), and vanillic acid(17). CONCLUSION: Compounds 1-16 are isolated for the first time from this plant.
