Antilipase activity guided fractionation of Vinca major
Methanolic extract of flowers of Vinca major (VFE) reduced the activity of porcine pancreatic lipase (PPL) which was reported in our previous study. To identify the antilipase molecule(s) in the VFE, the antilipase activity-guided fractionation for the purification of lipase inhibitory molecule(s) b...
