Thai Hom Mali rice is an economic crop of Thailand and well-known as a premium rice in the world trade. In this research, Thai Hom Mali rice samples were collected from the paddy fields in the northern and northeastern regions of Thailand for verifying the authenticity of rice origin. Multi-element and stable isotopic compositions in rice samples were determined by inductively coupled plasma mass spectrometry (ICP-MS) and isotope ratio mass spectrometry (IRMS), respectively. A radar plot was applied to discriminate the origin of rice. Thai Hom Mali Rice from both regions had similar pattern of isotopic composition. The two regions clearly displayed different distribution of elemental patterns. Therefore, Thai Hom Mali rice can be differentiated from each region using multi-element combined with a radar plot.
