Relationship of Gamma Oryzanol Accumulation to

Semi-gamma oryzanol and gamma oryzanol were estimated from an extraction of unpolished grain crude oil, using n-hexane and ethyl acetate. Contents were verified through a reverse-phase HPLC. C3G was extracted using 0.5%TFA in 95%ethanol. The relationships were estimated

  1. Semi-gamma oryzanol and gamma oryzanol were estimated from an extraction of unpolished grain crude oil, using n-hexane and ethyl acetate Contents were verified through a reverse-phase HPLC. C3G was extracted using 0.5%TFA in 95%ethanol The relationships were estimated by correlation coefficient analysis. Other nutrients were evaluated using a proximate analysis Kumnan Kumdoisaket Kum.7677 Kum.99151 Kum.87061 Kumomkoi KDML 105 RD 6 Relationship of Gamma Oryzanol Accumulation to Anthocyanin and Nutrient Content in Purple Rice Grain Panita Boonsit, Dumnern Karladee, Puntipa Pongpiachan and Suthat Julsrigival Faculty of Agriculture, Department of Agronomy, Chiang Mai University Introduction Relationship of Gamma Oryzanol (-oryzanol) accumulation to the content of Anthocyanin (cyaniding 3-glucoside: C3G), Ash, Crude Protein (CP), Crude Fiber (CF), Ether Extracted (EE) and Nitrogen Free Extract (NFE) was evaluated in 8 purple rice local varieties (Oryza sativa L.) and two white modern varieties (Oryza sativa L.). Material and Methods Result Table 1Gamma oryzanol content, Anthocyanin (C3G) content and seed nutrient in purple rice and white rice varieties Table 2 correlation between gamma oryzanol, anthocyanin (C3G) and seed nutrients Conclusion • Gamma oryzanol had a positive correlation with CF and CP but negative correlation with NFE • indicated, rice varieties with higher sources of cabohydrate would have less potential as a source of • gamma oryzanol. • There was no correlation between gamma oryzanol and C3G indicated, there was no linkage of both • gene control. • A negative correlation was found between C3G and Ash meant, pigmentation was no correlate with • seed nutrients.
