ABSTRACT:
The aim of the present study was to estimate flavonoid and phenolic content, and to evaluate invitro antioxidant activity of an aqueous extract of Alpinia nigra and Allium tuberosum. Methods: The air dried stem of A. nigra and leaves of A. tuberosum was ground to powder and extracted with water and 95% of ethanol. The extract was screened for phytochemicals, total phenolic content (TPC) and total flavonoid content (TFC) with its potential antioxidant activities using hydrogen peroxide-scavenging assay. Results: Phytochemical test shows that extract contains variety of phytochemicals among which there is a high level of total phenol and flavonoids. The total phenolic content (TPC) of A. nigra and A. tuberosum was 0.450±0.0740 and 1.663±0.296; respectively. The total flavonoid content (TFC) of A. nigra and A. tuberosum was 0.322±0.077 and 0.978±0.119, respectively. The plants possessed potent antioxidant activity when compared with the reference compound ascorbic acid (vitamin C). Conclusions: A. nigra and A. tuberosum may be useful for the preparation of neutraceuticals as potent antioxidant to treat various human diseases and their complications.
