Kim HJ, Lee DH, Hwang YY, Lee KS, Lee JS: Characterization of beta-hydroxy-beta-methylglutaryl coenzyme A reductase inhibitor from Pueraria thunbergiana. J Agric Food Chem. 2005 Jul 27;53(15):5882-8. This study describes the extraction and characterization of an inhibitor for beta-hydroxy-beta-methylglutaryl (HMG) coenzyme A (CoA) reductase from Pueraria thunbergiana. The maximum HMG-CoA reductase inhibitory activity (IC (50) = 79 microg) was obtained when P. thunbergiana was extracted with 70% ethanol at 30 degrees C for 12 h. After purification of the HMG-CoA reductase inhibitor by means of systematic solvent extraction, silica gel column chromatography, and HPLC, an active fraction with an IC (50) of 0.9 microg (4.25 microM) and a yield of 1.3% was obtained. The purified HMG-CoA reductase inhibitor was identified as daidzein (C (15) H (10) O (4); molecular mass, 254 Da). |
