(Moraceae), a traditional Chinese medicinal herb, has been extensively applied for many years to treat various diseases. Its fruits (Fructus Broussonetiae) have been commonly used as an important tonic for the treatment of age-related disorders with long history;recent research has proved that it contains 32% to 35% fixed oils. The fixed oil is composed mainly of unsaturated fatty acids, including linoleic acid, methyl palmitate, oleic acid and linoleic acid ester. Objective: To investigate the chemistry of the fatty oil from Fructus Broussonetiae (FOFB) and its effects on plasma lipids. Methods: The chemical composition of FOFB was examined and identified by GC-MS. Thirty male Wistar rats fed diet containing FOFB and cholesterol were studied for 28 days. The effect of dietary FOFB on plasma lipids and adipose tissue was tested. Results: Twelve compounds of FOFB were examined and identified, the major components of fatty oil, 8,11-octadecadienoic acid (83.75%), palmitic acid (10.22%), octadecadienoic acid (2.97%) and 9-octadecenoic acid (1.69%) were found. FOFB significantly exhibited the activities of decreasing the rat adipose tissue weight, triacylglycerol, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) concentrations while the rat body weight remained unchanged. Discussion: FOFB contained a large amount of PUFA which had the effect on reducing plasma lipids and adipose.展开更多
