Abstract

In this study, 50% ethanol extract prepared from air-dried leaves of nine plants grown wildly in Mongolia were characterized for their inhibitory activity of tyrosinase, α-glucosidase, hyaluronidase, lipase, and angiotensin I-converting enzyme (ACE) in order to identify potential new sources for dietary prevention of certain non-communicable diseases and skin health promotion from domestic plant kingdom. The results of this study indicate that out of the selected nine Mongolian plant leaves, V.vitis-idaeae, R.altissimum, and R.acicularis leaves presented strong inhibitory activity of mushroom tyrosinase, R.acicularis and P.anomala leaves exhibited good anti α-glucosidase and anti hyaluronidase activity, V.vitis-idaeae leaf showed appreciable inhibition of lipase activity, and P.anomala leaf effectively inhibited ACE. Among them P.anomala and R.acicularis leaves were found to be the most promising natural source with multiple biological properties.
