How data were acquired	Crude aqueous and methanolic leaf extracts of C. roseus and M. oleifera were isolated and analyzed by GC-MS, which was carried out on GC-MS QP2010 plus (Shimadzu, Japan) equipped with a flame ionization detector and GC 6890 model series. Several antioxidant activity in-vitro assays were performed with specified protocols. Antibacterial activities were determined using agar well diffusion method.
Data format	Raw, analyzed and expressed as mean ± SEM, One-way ANOVA analysis of variance.
Experimental factors	Aqueous and methanolic extracts of Catharanthus roseus and Moringa oleifera prepared to isolate secondary metabolites through GC-MS and tested in different in-vitro antioxidant assays and for antimicrobial activity.
Experimental features	Extraction and isolation of both plant crude extracts (Soxhlet, column chromatography, GC-MS analysis); In-vitro antioxidant assays (DPPH, FRAP, NO, H2O2.); Test microorganism (One Gram negative Escherichia coli (MTCC 443) and two Gram positive Bacillus subtilis (MTCC 441), Staphylococcus aureus (ATCC 259323).
Data source location	The fresh leaves of the two species of Catharanthus roseus and Moringa oleifera were gathered from campus of Yogi Vemana University and near Raychotighat, Kadapa, India, Department of Biotechnology and Bioinformatics, Yogi Vemana University, Kadapa, India.
