Abstract
Objective: The aim of this research was to investigate the antioxidant activity (AOA) of the methanolic extracts of different parts of Portulaca oleracea and Portulaca grandiflora.
 Methods: The plant different parts were extracted with methanol. The methanolic extracts of both species were screened for 2,2-diphenyl-1- picrylhydrazyl radical scavenging abilities and researched by gas chromatography-mass spectrometry (GC-MS) analysis.
 Results: GC-MS analysis of P. oleracea root extract revealed the presence of 39 biologically active compounds. 32 biologically active compounds were identified in P. grandiflora root extract. Both extracts revealed the AOA.
 Conclusion: The results of the investigation could be useful for further pharmacological and phytochemical researches to assess the beneficial properties of both these species.
Highlights
Nature always stands as a golden mark to exemplify the outstanding phenomena of symbiosis
The experimental samples taken for investigation were: P. oleracea root (POR), P. grandiflora root (PGR), P. oleracea herb, and P. grandiflora herb
It is evident that the methanolic root extracts of both species possess effective antioxidant activity (AOA) which may be due to the presence of respective phytocompounds
Summary
Nature always stands as a golden mark to exemplify the outstanding phenomena of symbiosis. As the people are becoming aware of the potency and side effect of synthetic drugs, there is an increasing interest in the natural product remedies with a basic approach toward the nature. Natural products isolated from various sources, especially derived from plants, have long been used in the treatment of human ailments. Herbal medicines are in great demand in the developed world for primary health care due to their efficacy, safety, and lesser side effects. A number of scientific investigations have highlighted the importance and the contribution of many plant families used as medicinal plants. Plants have a large unexplored range of compounds, which is almost impossible to imitate, they will always remain a potential source of future drug discovery
