Data on GC-MS analysis, in vitro anti-oxidant and anti-microbial activity of the and leaf extracts.

The article reports data on chemical profiling by gas chromatography-mass spectrometry (GC-MS) of aqueous and methanolic leaf extracts of Madagascar periwinkle () and drumstick tree () and on their antioxidant and antibacterial effects against three clinical human pathogens. In total 105 compounds were tentatively identified; in which 65 in and 40 in compounds. A large number of peaks with good area percentage was found in methanolic extract of with core chemical constituents such as -squalene, n-hexadecanoic acid, Eicosyl acetate, stearin, 1H-Benz(G)indole-3-carboxylic acid. The corresponding constituents from include 9-Octadecenoic acid (z)-, Heptadecanoic acid and phytol acetate. The highest scavenging activity (87.7% at 200 μg/mL) was shown by DPPH aqueous leaf extract of . Moreover, the methanolic scavenging of both plant extracts was in the order of FRAP>DPPH>NO> HO with lowest antioxidant activity (51.4% at 200 μg/mL) exposed by in comparison of all cases. Good antibacterial action was examined against three different organisms ( and ) of aqueous infusion of .
