This research was conducted to determine the total oryzanol content of various extracts and bioassay-guided isolation of active anti-hypercholesterolemic agent from Indonesian rice bran. Hot solvent extraction was done by reflux method using single and binary solvents, namely hexane, chloroform, ethyl acetate, dichloromethane, isopropanol, acetone, hexane-ethyl acetate (1:1, v/v), hexane-isopropanol (1:1, v/v), and chloroform-ethyl acetate (1:1, v/v). TLC densitometric was used to quantitatively analyze the total oryzanol content in various extracts. The hexane extract was selected for fractionation and evaluated for their anti-hypercholesterolemic activity. The structure of an isolated compound was determined on the basis of NMR and Mass spectroscopy. The total oryzanol content was obtained using various solvents ranging from 27.92 to 43.59 mg/100g rice bran, in which hexane extract showed the highest amount (43.59 ± 3.36 mg/100g rice bran). β-sitosterol has been isolated from rice bran hexane extract, which shows a significant decrease in serum total cholesterol level. In summary, hexane is the best solvent to extract oryzanol compound using reflux method, and β-sitosterol was suspected to be responsible for anti-hypercholesterolemic activity in addition to existing compound such as oryzanol that contained in the rice bran.

The aim of this study is to investigate the effects of dietary supplementation with the Driselase-treated fraction (DF) of rice bran and ferulic acid (FA) on hypertension and glucose and lipid metabolism in stroke-prone spontaneously hypertensive rats (SHRSP). Male SHRSP at 4 weeks of age were divided into three groups, and for 8 weeks were fed (1) a control diet based on AIN-93M, (2) a DF of rice bran-supplemented diet at 60 g/kg and (3) an FA-supplemented diet at 0·01 g/kg. Means and standard errors were calculated and the data were tested by one-way ANOVA followed by a least significance difference test. The results showed that both the DF and FA diets significantly improved hypertension as well as glucose tolerance, plasma nitric oxide (NOx), urinary 8-hydroxy-2′-deoxyguanosine and other parameters. In particular, compared to the FA diet, the DF diet produced a significant improvement in urinary NOx, hepatic triacylglycerol and several mRNA expressions of metabolic parameters involved in glucose and lipid metabolisms. The results of the metabolic syndrome-related parameters obtained from this study suggest that the DF diet is more effective than the FA diet.
