✦ Synopsis

Carbon-14 ltabelled gossypol has been prepared by incorporating 1 , 2 -C acetate in the growth medium of cold shocked cotton (Cossypium arboreum) seedling roots. Unlabelled gossypol was added during the purification procedure to aid crystallizftion; thus, from 350 seedling roots, 25 uCi sodium (1,2-C) (45-60 mCi/mmol) acetate and 800 mg of unlabelled gossypol; 350 mg of labelled gossypol (1900 dpm/mg) was isolated.

## Abstract A modification of our previously reported^2^ gas chromatographic method of preparing vinyl‐^14^C~2~ chloride (^14^C‐VC) has been made. The procedure using 1,2‐dichloroethane‐^14^C~2~ obtained from New England Nuclear Corporation gave good yields of ^14^C‐VC as a gas mixture with helium.
