Hypoglycemic effects of lactucin-8-O-methylacrylate of Parmentiera edulis fruit.

Hypoglycemic activity-guided fractionation together with chemical analysis led to the isolation of one guaianolide (lactucin-8-O-methylacrylate) from the chloroform extract of the dried fruits of Parmentiera edulis. Identification was based on spectroscopic methods. The compounds lowers blood sugar levels after administration to alloxan-diabetic mice.
