| Abstract: | A new glycoside was isolated as a minor metabolite in excised cotton leaves treated with either carbonyl-14C] or ring-14C] 3-(4-chlorophenyl)-1-methylurea and 4-chlorophenylurea. The aglycone from β-glucosidase or hesperidinase hydrolysis was identified as 4-chloro-2-hydroxyphenylurea by TLC, radioisotope dilution and MS. |
