Abstract

Three new chromanone derivatives, calopolyanic acid (1), isocalopolyanic acid (2), and isorecedensic acid (3), were isolated from the pericarps of Calophyllum polyanthum Wall. ex Choisy, along with seven known compounds, apetalic acid, blancoic acid, chapelieric acid, methyl isoapetalate, isoapetalic acid, isocalolongic acid, and recedensic acid. All of these compounds were reported from C. polyanthum for the first time. The structures of 1–3 were elucidated by spectroscopic methods.
