Abstract
Tobaccos as a cigarette material have some quality parameters. Some of chemical component such reducing sugar, chloride, and nicotine are used as standards of tobacco quality by chemical analysis. Taste, aroma, and colour are parametic variables that determined by organoleptic test subjectively by tobacco grader. Pigmen is the second greatest number of chemical component in tobacco after nicotine. Chlorophyll and carotenoid are pigment compound in tobacco, that degrade during senescence, curing process, and storage. Based on the background mentioned above, the aim of this research is to measure and investigate the colleration of leaf position, pigment compound, nicotine and reducing sugar, related in tobacco quality. This research uses the top, middle, and bottom leaf position at tobacco stem from several kinds of tobacco such as Temanggung and Bojonegoro. HPLC analysis at 425 nm wavelength shows that all of chlorophyll have degraded into pheophytin a as dominant chlorophyll derivate in already senescence, curing process, and storage. Otherwise, some carotenoids are present. The correlation of leaf position, reducing sugar, nicotine, and pigment compound, are indicating that pigment is able to be used as parametric variable. Therefore, it needs advanced study on other varieties of tobacco.
