After colep was applied to plants, the oxon analog was found in small 
amounts. The major amount of activity was apparently conjugated. Studies 

with acid and emulsin hydrolysis indicated the presence of phenyl B- 
glucoside and an a-glycoside. Another fraction contained phenyl sulfate. 
Acid hydrolysis of benzene, chloroform, and water extracts converted 
75-80% of the radioactivity to phenol for both cotton and apple, thus showing 
the association of the radioactivity with phenol-containing materials 
(Marco and Jaworski, 1964).
