Abstract
Details for the germination of cotton seedlings and their utilization for incorporating14C‐labeled acetate into gossypol are presented. Methods for the isolation and purification of the biosynthesized gossypol are given. The specific activity of the gossypol obtained from root tissue and cotyledons had mean values for 8 preparations of 428.6×103 and 6.3×103 dpm/mg, respectively. Corresponding incorporations were 5.42 and 0.32%.
