Abstract
Chemical compositions of Flue - cured and Burley tobacco leaf and smoke were analyzed to find out simple correlation between compositions. Based on the simple correlation ( $r$ ) data, four regression equations were obtained for dry condensate and nicotine in smoke as follows, $Y_{FT}=\;0.816+4.638X_1+0.346X_2$......................................(1) $Y_{BT}=\;0.235+0.884X_3-0.088X_4$......................................(2) $Y_{FN}=\;0.015+0.090X_5+0.476X_1$......................................(3) $Y_{BN}=-0.026+0.101X_3-0.006X_4$.........................................(4) where, $Y_{FT}$ : dry condensate (mg/cig.) in cigarette smoke of Flue-cured $Y_{BT}$ : dry condensate (mg /cig. ) in cigarette smoke of Burley $Y_{FN}$ : nicotine contents (mg/cig.)in cigarette smoke of Flue-cured $Y_{BN}$ : nicotine contorts (mg/cig. ) in cigarette smoke of Burley $X_1$ : total alkaloid contents (%) of Flue-cured $X_2$ : curde ash contents (%)of Flue -cured $X_3$ : alcohol -benzene extract contents (%) of Burley $X_4$ : curde ash contents (%) of Burley $X_5$ : hexane extract content (%) of Flue -cured Standard deviation for regressions equations were obtained respectively. equation(1),$\pm$3.16 : equation (2),$\pm$1.94 : equation (3),$\pm$0.35 , equation (4) $\pm$ 0.33. Regression equations between dry condensate and nicotine contorts in cigarette smoke were also obtained in the forms of equation(5) and(6) $Y_{FN}$= 0.274 $Y_{FT}$- 3.259............................(5) $Y_{BN}$= 0.249 $Y_{BT}$ - 2.093.............................(6) Standard deviations, $\pm$ 0.061 and $\pm$ 0.152, were obtained for regression equation(5) and (6) respectively.
1978년 우리나라에서 경작한 잎담배 Flue -cured와 Burley의 조성 및 권련 연기중의 dry condensate와 nicotine 과의 상관성을 조사하고 dry condensate 와 nicotine 의 량을 추정할 수 있는 방정식을 얻었다. $Y_{FT}=\;0.816+4.638X_1+0.346X_2$......................................(1) $Y_{BT}=\;0.235+0.884X_3-0.088X_4$......................................(2) $Y_{FN}=\;0.015+0.090X_5+0.476X_1$......................................(3) $Y_{BN}=-0.026+0.101X_3-0.006X_4$.........................................(4) $Y_{FT}$ : Flue -cured사용 권련 연기중 dry condensate (mg/cig.) $Y_{BT}$ : Burley사용 권련 연기중 dry condensate (mg/cig.) $Y_{FN}$ : Flue -cured사용 권련 연기중 nicotine ( mg/cig.) $Y_{BN}$ : Burley사용 권련 연기중 nicotine ( mg/cig.) $X_1$ : Flue -cured잎담배 중의 total alkaloid (%) $X_2$ : Flue -cured잎담배 중의 crude ash (%) $X_3$ : Burley 잎담배 중의 alcohol benzene extract (%) $X_4$ : Burley잎담배 중의 crude ash (%) $X_5$ : Flue -cured잎담배 중의 hexane extract (%) 이 식에서 추정한 값과의 표준편차는 식(1)$\pm$3.16, 식(2)$\pm$1.94, 식(3)$\pm$0.35,식(4)$\pm$0.33이였다. 연기중의 nicotine과 dry condensate사이에는 $Y_{FN}$= 0.274 $Y_{FT}$- 3.259............................(5) $Y_{BN}$= 0.249 $Y_{BT}$ - 2.093.............................(6) 였으며 표준편차는 각각 $\pm$0.061과 $\pm$0.152이였다.
