A Comparative Study between Aqueous and Ethanolic Extracts of Allium Odorum Linn with Reference to its Antioxidant and AlphaAmylase Inhibition Activities

Abstract

Allium odorum Linn belongs to the family Liliaceae which is established as a potent medicinal plant in folkware medicinal system. The plant is native to China as well as Japan and also cultivated in North-east part of India as an essential part of culinary. In this study, leaves of this plant were collected from Imphal East district of Manipur and extracted in water and ethanol. The extracts were screened for the presence of various bioactive compounds and its inhibition activity against α-amylase. Both aqueous and ethanol extracts showed presence of bioactive compounds like sterol, tannin, saponin, di-terpines and sugars whereas bioactive compounds like flavonoid, glycoside, and amino acids were present only in ethanol extracts Major bioactive compound like alkaloid test showed neg. result during the study. The sample was also found to exhibit a maximum of 89.27% and 69.79% of α-amylase inhibition activity in ethanol and water extract resp. When sample was subjected to its antioxidant activity it exhibited 84.85% and 65.88% by DPPH method and a maximum of 67.73% and 57.97% by H2O2 method in ethanol and water extract resp. Hence, from this study the sample can be used as a potential source for anti-oxidant and anti-diabetic agent which will help us to substitute some com. available synthetic drugs near future.
