Abstract
BackgroundThe aim of the present study was to analyse the effect of climate change on phytochemicals, total phenolic content (TPC) and antioxidant potential of methanolic extracts of Aloe vera collected from different climatic zones of the India.MethodsCrude methanolic extracts of A. vera from the different states of India were screened for presence of various phytochemicals, total phenolic content and in vitro antioxidant activity. Total phenolic content was tested by Folin–Ciocalteau reagent based assay whilst DPPH free radical scavenging assay, metal chelating assay, hydrogen peroxide scavenging assay, reducing power assay and β carotene-linoleic assay were used to assess the antioxidant potential of A. vera methanolic leaf extracts.ResultsAlkaloids, phenols, flavonoids, saponins, and terpenes were the main phytochemicals presents in all accessions. A significant positive correlation was found between TPC and antioxidant activity of different accessions. Extracts of highland and semi-arid zones possessed maximum antioxidant potential. Accessions from tropical zones showed the least antioxidant activity in all assays.ConclusionsIt could be concluded that different agro-climatic conditions have effects on the phytochemicals, total phenolic content (TPC) and antioxidant potential of the A. vera plant. The results reveal that A. vera can be a potential source of novel natural antioxidant compounds.

Summary
The aim of the present study was to analyse the effect of climate change on phytochemicals, total phenolic content (TPC) and antioxidant potential of methanolic extracts of Aloe vera collected from different climatic zones of the India. Climate change is causing noticeable effects on the life cycle, distribution and phyto-chemical composition of the world’s vegetation, including medicinal and aromatic plants. The changing temperatures and wind patterns associated with climate change are affecting precipitation and thereby plant architecture, flowering, fruiting, phytochemical composition and in situ competition with other species. There is a need to Antioxidative action is one of the prime physiological functions that protect living organisms from oxidative damage caused by reactive oxygen species (ROS). During daily activities and with advanced age, oxidative substances and free radicals accumulate in cells affecting various organs and
