Fig. 5. A. Radiochromatograms of water-soluble fractions 1 and 2 from anion ex- 

 change column; Sh 39 and 40 are fraction 1 in two different solvents; No. 47 is frac- 

 tion 2 in one solvent. B. Main metabolite chromatographed in two solvents before 

 purification (Sh 41 and 42) and after purification (Sh 43 and 44). C. Ch 61-a and 

 Ch 61 -b — radiochromatograms of crude water extract from cotton showing seven 

 radioactive bands. Ch 60 — same extract chromatographed in different solvent and 

 b band eluted and re-chromatographed. D. Sh 44b — two dimensional radiochro- 

 matogram of purified cotton metabolite developed in Bandurski and Axelrod 

 solvents.
