Contents of Fructose, Glucose, Sucrose, and Starch in Flue-cured Tobacco Leaves.

황색종 잎담배중의 탄수화물 함량조사 연구

Flue-cured tobacco leaves, produced in Korea and in the USA in 1980, were analyzed for their sugar contents. Regardless of tobacco varieties or production localities, glucose was the most abundant and sucrose the lowest among free sugars. In terms of total sugar, USA-produced leaves contained the highest concentration in the grade of $C_3F$ (equivalent to the $L_3$ grade in Korean standard) , but Korea produced ones in the grades of the $H_1\;and\;L_1$, (equivalent to the $B_1F\;and\;C_1F$ grades, respectively, in the USA standard) . Otherwise, we could not find any significant differences in sugar contents between American and Korean tobacco leaves.
