Objective: Four different extracts of Araucaria columnaris (bark peel) and Cosmos sulphureus (flowers) were screened for their phytochemical composition, and free radical scavenging activities.Methods: DPPH method was used to test the antioxidant activity for extracts.Results: Among the different extracts tested, the methanol extract of both the plant species showed significant radical scavenging activities. Phytochemical analysis of the extracts revealed that the radical scavenging activities might be due to the presence of flavonoids, tannins and phenolic compounds.Conclusion: The results obtained suggest that Araucaria columnaris (bark peel) and Cosmos sulphureus(flowers) could be exploited in the treatment of various diseases like cancer, cardiovascular diseases and infection diseases.

Objective: The current investigation was contemplated to evaluate the phytochemicals and in vitro antioxidant activities in peel and pulp of some commercially grown citrus fruits of South India, namely, lemon (Citrus aurantifolia), orange (Citrus reticulata), sour orange (Citrus aurantium), pomello (Citrus grandis), and citron (Citrus medica).Methods: The peel and pulp of the fruits were separated and subjected to cold extraction using 70% alcohol. The extracts obtained were screened for the presence of their phytoconstituents using various qualitative and further quantified for major constituents. Further, the in vitro antioxidant activity was assayed by different radical scavenging methods, namely, 2,2-diphenyl-1-picrylhydrazyl, superoxide anion, nitric oxide, lipid peroxidation inhibition, iron chelating activity, and reducing power assay at different concentrations.Results: All the citrus fruits have shown significant in vitro antioxidant activity for the parameters assessed, wherein peel extracts recorded superior antioxidant potential than their corresponding pulps. The broad range of activity of the extracts suggests that multiple mechanisms mediated by the phytoconstituents are responsible for the antioxidant activity.Conclusion: The study thus revealed that peel and pulp of citrus fruits are potential sources of bioactive compounds which are reflected in antioxidant activity and supports their health-promoting claims of plethora of investigations.
