摘要: AIM:Artemisia amygdalina Decne.(Asteraceae) is a critically endangered and endemic herb of Kashmir Himalayan sub-alpine region and Pakistan.Scientific research throughout the world has evidence to support the tremendous medicinal utility of the genus Artemisia.The natural resources of medicinal plants are being reduced day by day.This study provides the alternative way for medicinal resource utilization and conservation of A.amygdalina.METHODS:In vitro-raised plants and greenhouse acclimatized plants were obtained by culturing wild explants on Murashige and Skoog's medium.Plant extracts were obtained and subjected to different antioxidant assays:DPPH assay,riboflavin photo-oxidation assay,deoxy ribose assay,ferric thiocyanate assay,thiobarbituric acid assay,post mitochondrial supernatant assay and DNA damage on agarose gel.RESULTS:In vitro grown plants,as well as those acclimatized in the greenhouse reveals antioxidant activity against hydroxyl,superoxide,and lipid peroxyl radicals.CONCLUSION:This preliminary study revealed the free radical scavenging potential of tissue culture-raised plant extracts of A.amydalina.
