クスレー抽出装置に投入し、本発明の抽出溶媒組成物を
用い８時間加熱還流を行った。加熱還流後の溶媒を蒸発
乾個し、抽出量を測定した。A predetermined amount of a tobacco sample (Highlight, commercially available product) was placed in a Soxhlet extraction device, and heated under reflux for 8 hours using the extraction solvent composition of the present invention. After heating to reflux, the solvent was evaporated to dryness, and the amount extracted was measured.
その結果を第１表に示す。比較溶媒としてメタノールを
用い、同様の試験を行った。この場合の抽出量を１００
とし、それに対する比率で示した。The results are shown in Table 1. A similar test was conducted using methanol as a comparative solvent. In this case, the extraction amount is 100
It is expressed as a ratio to that amount.
