Hypoglycemic and hypolipidemic properties of oil derived from Agrius convolvuli

Abstract

This study aims to determine the hypoglycemic and hypolipidemic properties of oil derived from Agrius convolvuli (Lepidoptera: Sphingidae) in KKAy mice, a cross between diabetic (KK) and lethal yellow (Ay) mice. A group of 12 KKAy mice were fed with AIN-76 feed containing oil derived from A. convolvuli pupae (ACPO) while another group of 12 KKAy mice were fed with AIN-76 feed without ACPO, for 6 weeks. Compared with the control group, the KKAy mice fed with the ACPO diet had decreased serum insulin, glycogen, fasting blood glucose, triacylglycerol, total cholesterol and low-density lipoprotein cholesterol level, but had increased serum high-density lipoprotein cholesterol level, linolenic acid content and total polyunsaturated fatty acid content. The results indicate that ACPO has hypoglycemic and hypolipidemic properties and may be a suitable alternative food supplement for humans.
