Abstract
Extraction of bitter carrots with hexane yielded a colorless, optically active, crystalline substance, CIIHI~ O~,(I). The substance is a lactone with one phenolic, one methoxyl and one C-methyl group. Infrared absorption data indicated 313 8-hydroxy-3, 4- dihydroisocoumarin derivative. The methyl ether of I gives a positive iodoform test and is oxidized by alka-line permanganate to 3, 5-dimethoxyphthalic acid. Potassium hydroxide ...
