GC-MS Analysis and Preliminary Antimicrobial Activity of (Schumach) and (DC).

The non-polar components of two leguminoceae species (Schumach), and (DC) were investigated. GC-MS analysis of the crude -hexane and chloroform extracts together with several chromatographic separation techniques led to the identification and characterization (using NMR) of sixteen known compounds from the heartwood and stem bark of and respectively. These constituents include, -hexadecanoic acid (palmitic acid) , oleic acid , chondrillasterol , stigmasterol , 24S 5α-stigmast-7-en-3β-ol , 9,12-octadecadienoic acid (,)-, methyl ester , 13-octadecanoic acid, methyl ester , tetradecanoic acid , hexadecanoic acid, methyl ester , octadecanoic acid , tetratriacontane , 7-dehydrodiosgenin , lupeol , stigmasta-3,5-diene-7-one , friedelan-3-one (friedelin) , and 1-octacosanol . Using agar over lay method, the preliminary antimicrobial assay for the extracts was carried out against bacterial (, , , ) and a fungus/yeast () strains. The -hexane and chloroform extracts of showed the best activity against with minimum inhibition quantity (MIQ) of 1 µg each while the remaining exhibited moderate-to-weak activity against the test microorganisms.
