Loomis' mountain mint, Nuttall, is a species of mint native to the American Southeast. In the present study, 38 odorants were identified employing aroma extract dilution analysis (AEDA) performed on a distillate prepared by solvent extraction and solvent-assisted flavor evaporation (SAFE) distillation of dried . Seven odorants with flavor dilution (FD) factors ≥16 were quantitated using stable isotope dilution assays (SIDA), and their odor activity values (OAV) were calculated. In addition, the stereochemical composition of chiral odorants was also determined by chiral chromatography. Odor simulation experiments demonstrated that when 1,8-cineole (eucalyptus; OAV 6400), linalool (floral, citrus; OAV 120), β-ionone (floral, violet; OAV 86), borneol (earthy; OAV 56), and eugenol (clove; OAV 2.5) were combined in their natural concentrations, the model successfully mimicked the plant's aroma. The results of this investigation provide a foundation for additional investigations into the natural variation in aroma chemistry of different selections of and other members of the genus.
Loomis' 山薄荷，Nuttall，是薄荷属的一种植物，原产于美国东南部。在本研究中，采用溶剂萃取和溶剂辅助风味蒸发（SAFE）蒸馏干燥的方法制备馏出物，通过香气提取稀释分析（AEDA）鉴定了 38 种香气物质。使用稳定同位素稀释分析（SIDA）定量测定了 7 种风味稀释（FD）因子≥16 的香气物质，并计算了它们的气味活度值（OAV）。此外，通过手性色谱还确定了手性香气物质的立体化学组成。气味模拟实验表明，当 1,8-桉叶油醇（桉树；OAV6400）、芳樟醇（花香、柑橘；OAV120）、β-突厥酮（花香、紫罗兰；OAV86）、龙脑（泥土；OAV56）和丁香酚（丁香；OAV2.5）以其自然浓度结合时，该模型成功模拟了植物的香气。本研究的结果为进一步研究不同品系的 和其他薄荷属植物的香气化学自然变异提供了基础。
