摘要

从雪茄烟（Nicotiana tabacum 的一个变种）的茎中分离出了两种新的芳香倍半萜，即 2-(3-异丙基-4,5-二甲氧基苄基)-4-甲基呋喃（1）和（5-(3-异丙基-4,5-二甲氧基苄基)呋喃-3-基）甲醇（2）。通过光谱方法，包括广泛的一维和二维核磁共振技术，确定了它们的结构。有趣的是，化合物 2 具有微弱的甜香。它们可以增强雪茄烟的甜香风格，具有作为雪茄烟香精使用的潜在价值。

Two New Aromatic Sesquiterpenes from Cigar Tobacco and Their Effects on the Aroma of Cigars

Two new aromatic sesquiterpenes, 2-(3-isopropyl-4,5-dimethoxybenzyl)-4-methylfuran (1) and (5-(3-isopropyl-4,5-dimethoxybenzyl)furan-3-yl)methanol (2) were isolated from the stems of cigar tobacco (a variety of Nicotiana tabacum). Their structures were determined by spectroscopic methods, including extensive 1D and 2D NMR techniques. Interestingly, compound 2 has a weak, sweet fragrance. They can enhance the sweet aroma style of cigar smoke and have potential value for use as an essence for cigar tobacco.
