Two new alkylanacardic acids, ozorcardic A and B, from Ozoroa pulcherrima.

Two new alkylanacardic acids, ozorcardic A (1) and B (2), along with the known and related metabolite anacardic acid (3), were isolated from Ozoroa pulcherrima. The structures of the new compounds were elucidated by detailed spectroscopic and spectrometric analysis.

Ozocardic A: a new alkylanacardic acid from Ozoroa pulcherrima.

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