Chemical investigation of the seed extract of Senna occidentalis l.
Abstract
The seeds Senna occidentalis were successively extracted with n-hexane and 95 % ethanol. The n-hexane extract highly rich in fatty acid was subjected to transmathylation to allow the sample ready for looms. The
extract (SH and SE) were analyzed using high resolution gas chromatography and spectrometer. The comparison of their GC, retention indices and mass spectro characteristics with the stored laboratory mass
spectral library data, led to the identification of phyto-chemical aspect of the seed. The aim of the study was to qualitatively determine the organic compound of the seed of Senna occidentalis. Thirteen compounds were identified in n-hexane extract and in ethanolic extract twelve compounds were identified. The prevailing compound in n-hexane extract was palmetric acid (17.96 %). Other compounds such as aldehydre, lactone and chloride were present. Octadecanoic acid as fatty acid was identified as the main constituent (22.56%) of ethanolic extract. The study has gone a long way to validate scientifically the major phytochemical properties of the seed of Senna occendentalis.
