Technique nuclear magnetic resonance spectroscopy year's
application of the characteristics of rice varieties, Thailand Jasmine (B 15, B 29 and B 31), to distinguish strains of rice. By extracting heat grain Rice strain B 15, B 29 and B 31 and paddy strains RD15 way reflux for 30 minutes with solvent isometric propanol million (isopopanal) extracted 10 times. volatile solvent Rice extract When the rice extract studied by thin-layer chromatography Chromatography (Thin-layayer. Chromatography, TLC) the solvent system moves Hexane: Chloroform ratio of 3: 7 and extract rice studied by nuclear magnetic spectroscopy year (Nuclear Magnetic Resonance Spectrosocopy a T1 and T2, the study found the Rf T1. and T2 extract, rice, jasmine (B
15, B 29 and B 31) is specific to each species can be
classified species, the three apart and also found that the use of
grain for extraction analysis. Characteristics of rice keywords. Thailand Jasmine rice varieties (A, B 15, B 29 and B 31) Rice Thailand NMR . Prof. Dr.
