BACKGROUND
To find new, crude anti-obesity drugs from natural sources through the inhibition of adsorption of dietary lipids, in vitro porcine pancreatic lipase (PPL; triacylglycerol lipase, EC 3.1.1.3) inhibitory tests were carried out on selected plants with weight-reducing or related potential,
Emodin, one of the main active components in the root and rhizome of Rheum palmatum L, promoted the conversion of 3T3-L1 fibroblasts to adipocytes, as evidenced by increased glycerol-3-phosphate dehydrogenase (GPDH) activity and the expression of adipocyte aP2 mRNA, as well as accelerated
