Secondary Metabolites of Plukenetia volubilis
摘要
A new ketone, volubilisone A (1), along with seven known compounds including trans-methyl-p-coumarate (2), methyl-p-methoxybenzoate (3), coniferyl aldehyde (4), methyl ferulate (5), ferulic acid (6), p-coumaric acid (7), and protocatechuic acid (8), were isolated from the seed shells of Plukenetia volubilis L. (Euphorbiaceae). The structure of the new hexenone derivative was elucidated by chemical and physical evidence.
