dc.description.abstract | Stigmaphyllom paralias is a herb belonging to the family Malpighiaceae that occurs in sand soil of brazilian " restinga". This is the first report regarding phytochemical study with this species. The hexane extract of the aerial parts of plant afforded the triterpenes friedelin, lupenone, 3-oxo-a-amirin and 3-oxo-b-amirin, the mixture of a-amirinyl palmitate and stearate, lupeol and 3,4-seco-friedelan-3-oic acid. The AcOEt extract yielded the flavonoid luteolin-7-rutinoside. All compounds were characterized by analysis of spectrometric data and the fatty acids esterified with a-amirine were identified by GC/MS of methyl derivatives of transesterified products . This is the first natural occurence of 3,4-seco-friedelan-3-oic acid and the 13C NMR spectral data were inequivocally assigned by two-dimensional techniques. This work also permitted to correct the 13C NMR resonances attributed to methyl groups C-26 and C-27 of fridelin. | pt_BR |
