25W, water extract at room temperature; 80W, water extract by reflux extraction at 80°C; 110W, water extract by pressure heating extraction at 110°C.
Values are mean±SD of triplicate determinations.
Values with different superscript alphabet in the same raw were significantly different among group at p<0.05 level by Duncan’s multiple range test.
