Abstract
The isolation and structural elucidation are reported of a new triterpenoid alcohol from ferulates in rice bran oil. The new alcohol, mp 156.5157.5°C, [α] D+38.4° was assigned the molecular formula C31H52O on the basis of the elementary analysis, molecular weight and mass spectrum, and was named cyclobranol by us. The structure of cyclobranol was deduced 24-methyl-cycloartenol byr the spectral evidence and the retention time of gas chromatography.
