“…Refined cottonseed oil is also rich in some (CVJ, C2l, and C29) of the odd-numbered hydrocarbons (Kuksis, 1964) but differs significantly from buds and flowers in that the total amounts of C23, C2S, and C27 (including normal, iso, anteiso, and cyclohexyl types) are less than 1 %; another significant difference is the presence of relatively large amounts of the even-numbered hydrocarbons C20 and C30. Many workers (Del Castillo et al, 1967;Eglinton et al, 1962a, b;Farnsworth et al, 1967a;Hargreaves, 1966; Manni and Sinsheimer, 1965;Suzuki et a!., 1966) have likewise found that the odd carbon atom compounds are predominant in other plants.…”
