The phytosterol levels in 22 cultivars varied from 255.0 mg/kg rice in Daerip to 492.0 mg/kg rice in Kuennun and the major phytosterol was β-sitosterol in all cultivars. In all the cultivars, there was a high correlation coefficient (R2 = 0.7996) between the lipid level and the phytosterol level. The major tocols homologues in the 19 Japonica type cultivars were α-tocopherol and α-tocotrienol, and the major homologue in the Indica type cultivars namely Segyuejinmi, Hanareum, and Dasan No.1 was γ-tocotrienol. Among the γ-oryzanol species, the proportions of cycloartenylferulate in Japonica type cultivars were significantly higher than those of 24-methylene cycloartanylferulate (p < 0.05). This study provided information on lipid soluble substances level, such as tocols, phytosterol and γ-oryzanol, in different rice cultivars. http://pubs.sciepub.com/jfnr/2/1/7/jfnr-2-1-7.pdf brown rice cultivarstocolsæ-Oryzanolphytosterolssqualene
