Ozocardic A: a new alkylanacardic acid from Ozoroa pulcherrima

Abstract

One new alkylanacardic acid, ozocardic A (1), along with the known and related metabolites 6-tridecyl anacardic acid (2) and β-sitosterol (3) was isolated from Ozoroa pulcherrima. The structure of the new compound was elucidated by detailed spectroscopic analysis such as ¹H, ¹³C NMR, COSY, HMQC, HMBC, and HREIMS. The structures of known compounds (6-tridecyl anacardic acid (2) and β-sitosterol (3)) were identified by the comparison of their spectral data with those published in the literature.
