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 -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. http://pubs.sciepub.com/jfnr/6/2/1/jfnr-6-2-1.pdf tyrosinase hyaluronidase α-glucosidase lipase angiotensin I-converting enzyme inhibitory activity plant leaves
