摘　　要：Honey is a product of the elaboration of flower nectar by bees. The general features and elemental composition of honey depend on its botanical origin. In this study, five color parameters （L＊： lightness, a＊： red color, b＊： yellow color, C＊ab and hab） and five elements （Na, K, Mg, Ca and Zn） were determined and related with 91 Thai honey samples. The origins of four botanic types of （1） longan flower （Dimocarpus sp.）, （2） lynchee flower （Litchi sp.）, （3） sunflower （Helianthus sp.） and （4） wild flower （Eupatorium sp.） using principle component analysis （PCA）. The results showed that five color parameters and five metal contents related with the Thai botanic origins of the honeys using principle component analysis （PCA）. Six major indicators of PC i （variance is 44.33%） from three color parameters are L＊（-0.926）, a＊（0.927） and hue or hab （0.824） and from three metal contents are K（0.833）, Ca（0.816） and Mg（0.595）. Two minor indicators of PC2 （variance is 21.58%） from color parameters are b＊（-0.934） and Chroma or C＊ab （-0.834）. Two indicators of PC3 （%variance is 12.47%） from contents of Na （-0.722） and Zn （0.704）. Thai Lynchee （C） flower honeys classified using both six parameters in PC 1 and two color parameters in PC2. Thai longan flower （G） honeys classified using the contents of Zn and Na in PC3 parameters. Thai sunflower （S） honeys classified using two color parameters in PC2. Thai wild flower （W） honeys classified using the metal contents of K in PC 1 parameter, Zn and Na in PC3 parameters.
