Abstract

The total crystalline product of Egyptian rice bran oil (yield, 1.2 %), obtained by a procedure under patent was fractionated on a column of alumina. As a result, six crystalline sterols and triterpene alcohols were isolated and characterised. One of the isolated materials was identified as β-sitosterol (the main constituent); two have characters similar to those of 25–ethoxycycloartanol and cyclobranol, respectively; three are most probably isolated for the first time from the oil.
