Antioxidant Potential of Angelica glauca of Uttarakhand Region

Abstract

In the present work, the effect of altitudinal variations on the total phenol, flavonoid, and antioxidant potential of seeds of Angelica glauca collected from 17 different locations of Uttarakhand has been investigated. Methanolic and acetonic extracts of seed showed significantly increasing amounts of total polyphenol content, and antioxidant potential with rising altitude. Methanolic extract of seed were found to have significantly greater polyphenol, and antioxidant potential as compared to acetonic extract. The methanolic seed extract of Bageshwar (3,353 m) showed the maximum total phenolic content 1,521 μg gallic acid equivalent/ 50 mg of dry weight. The methanolic seed extract of Bageshwar showed the maximum antioxidant activity in βcarotene (77.7 %) and DPPH activity (37.4 %) also. The results of this study exhibited good correlation with total polyphenol and antioxidant potential in all the samples followed by the increasing tendency towards rising altitude.
