Morinda citrifolia, has been reported to posses different biological activities and almost all parts of this have been studied phytochemically. However there are few studies on the seeds of fruit. The objective of present study was investigated the effect to Noni Seed Oil (NSO) on serum lipid levels in normolipidemic and hyperlipidemic induced mice. We find that administration of noni oil causes a reduction in total cholesterol and triglycerides levels in both models. However hypolipidemic effect is higher when hyperlipidemia is presented.
