摘要
Commercial moist snuff was extracted by using supercritical carbon dioxide at 60-degrees-C and 8000 psi for a period of 20 min. A wide variety of components were extracted and identified, and several of them were quantitatively assayed. Nicotine was quantified with high precision and reproducibility (RSD 4.1%). The enhancement of the extraction due to addition of a polar entrainer like methanol was investigated.
