A New Long-Chain Unsaturated Ester and Other Constituents of Hypericum tomentosum

Three long-chain unsaturated esters (1-3), a fatty acid (4), a fatty ester (5), phytone (6) and a phloroglucinol (hyperfoliatin) (7) were isolated from the light petroleum extract of the endemic species Hypericum tomentosum L. (Clusiaceae). Compound 2, 8,10,13-trimethyltetradecanoic acid (2E)-3-meth...

Description
Summary:Three long-chain unsaturated esters (1-3), a fatty acid (4), a fatty ester (5), phytone (6) and a phloroglucinol (hyperfoliatin) (7) were isolated from the light petroleum extract of the endemic species Hypericum tomentosum L. (Clusiaceae). Compound 2, 8,10,13-trimethyltetradecanoic acid (2E)-3-methylhexadec-2-enyl ester, which we named tomentosate, is reported for the first time. The structures of the identified compounds were established on the basis of physical and spectroscopic analysis, and by comparison with literature data.
