Abstract:
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.

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
