Abstract

Members of the genus are well known for their medicinal properties, which can be attributed to their essential oils. In this work, we have examined the leaf essential oils of five understudied species collected from various locations in western North America. The essential oils were obtained by hydrodistillation and analyzed by gas chromatographic methods, including enantioselective gas chromatography. was dominated by (+)-δ-3-carene; was dominated by α-pinene (mostly (+)-α-pinene) and (-)-β-pinene; was dominated by (-)-β-pinene; was dominated by (-)-β-pinene, (+)-δ-3-carene, and (-)-α-pinene; and was rich in (-)-α-pinene and limonene. While this work adds to our knowledge of essential oils, additional research is needed to more fully appreciate the geographic and altitudinal variations in the volatile compositions of these species.

摘要

该属成员因其药用特性而闻名，这可归因于它们的精油。在这项工作中，我们研究了从北美西部不同地点采集的五个研究较少的物种的叶精油。通过水蒸馏法获得精油，并采用气相色谱法进行分析，包括对映选择性气相色谱法。以(+)-δ-3-蒈烯为主；以α-蒎烯（主要是(+)-α-蒎烯）和(-)-β-蒎烯为主；以(-)-β-蒎烯为主；以(-)-β-蒎烯、(+)-δ-3-蒈烯和(-)-α-蒎烯为主；富含(-)-α-蒎烯和柠檬烯。虽然这项工作增加了我们对精油的了解，但还需要更多研究来更全面地认识这些物种挥发性成分的地理和海拔变化。
