Chemical characterization, antioxidant activity, -amylase and acetylcholinesterase inhibitory potential of Angelica pancicii Vandas ex Velen

Abstract

Comparative study GC-FID/MS of essential oils of fruits, leaves and roots of the endemic plant Angelica panciciiVandas ex Velen. revealed a significant difference in their chemical composition. The enantiomeric purity of the main component in the fruit oil (+)-β-phellandrene was also confirmed. In addition, imperatorin, isoimperatorin, oxypeucedanin, oxypeucedanin hydrate, angeloylpangelin and umbelliprenin were isolated from the fruit hexane extract. The content of these coumarins in the hexane extracts from different plant parts was further determined by HPLC. The essential oils and hexane extracts were assessed for their antioxidant potential and inhibitory effect towards -amylase and acetylcholinesterase enzymes. The fruit and leaf essential oils (> 80%) as well as the fruit hexane extract (> 62%) significantly inhibited acetylcholinesterase enzyme. Distinguish free radical scavenging properties were detected for the leaf (Inh. 95.0 ± 2.2 %) and the root (Inh. 66.0 ± 2.4 %) extracts.
