Chemical constituents from the stem bark of pandanus tectorius / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents in the stem bark of Pandanus tectorius Soland. METHODS: Compounds were isolated by repeated chromatography. Their structures were elucidated by spectroscopic methods. RESULTS: Thirteen compounds were isolated and identified as 3-hydroxy-2-isopropenyldihydrobenzofuran-5-carboxylic acid methyl ester (1), pinoresinol (2), epi-pinoresinol(3), salicifoliol(4), thero-2, 3-bis-(4-hydroxy-3-methoxyphenyl) -3-ethoxypropan-1-ol(5), erythero-2, 3-bis-(4-hydroxy-3-methoxyphenyl) -3-ethoxypropan-1-ol(6), eudesmin A (7), loliolide (8), pinoresinol-4-O-β-D-glucoside (9), protocate-chuic acid(10), caffeic acid(11), p-hydroxybenzoic acid (12), and ferulic acid (13). CONCLUSION: All the compounds are isolated from this plant for the first time.
