Abstract: In this study, the moisture, protein, fat, soluble sugar, ash and VB2 of red glutinous rice planted in Changshu, Xuzhou, Dafeng, Huaian, Shanghai and Henan were determined. Meanwhile, the contents of mineral elements such as Na, Mn, Cu, Zn, Ca, Fe and Mg were assayed by flame atomic absorption spectroscopy, and the contents of 17 common amino acids were analyzed. The results showed that the contents of protein, fat, ash, VB2 and the mineral elements Mg (especially higher, a 1.33-fold increase), Zn, Mn, Fe and Cu of red glutinous rice samples investigated were all higher than those of common rice. The 6 essential amino acids VB2, Leu, Val, Met, Sys, Thr and Lys all exhibited a higher content in the red glutinous rice samples compared with Japonica rice.
