Abstract

Essential oil from the aerial parts and flowers of Glossocardia bosvallia (L.f.) DC. was analysed using GC, chiral GC, GC-MS and NMR spectroscopy. Chemical composition and identification of compounds in the essential oils were determined by GC and GC-MS analysis respectively. GC analysis depicted β-myrcene as the major compound in both the essential oils, aerial parts containing 61.59% and flowers constitutes 44.86%. Occurrence of β-myrcene was also confirmed using 1H, 13C and DEPT 135° NMR spectroscopy. Chiral GC illustrated the enantiomeric composition of monoterpene hydrocarbons, in which (1S)-(-)-β-pinene, (-)-sabinene and (4S)-(-)-limonene were the major enantiomers. The present study reports the essential oil composition and enantiomeric composition of β-myrcene rich G. bosvallia essential oil for the first time. G. bosvallia essential oil can be a good source of β-myrcene, a compound with wide range of biological properties.

来自 Glossocardia bosvallia (Lf) DC 的富含 β-月桂缔精油的化学成分和手性分析。

摘要

来自Glossocardia bosvallia (Lf) DC地上部分和花朵的精油。使用 GC、手性 GC、GC-MS 和 NMR 光谱分析。精油中的化学成分和化合物鉴定分别通过 GC 和 GC-MS 分析确定。气相色谱分析表明,β-月桂烯是两种精油中的主要化合物,地上部分含量为 61.59%,花朵含量为 44.86%。还使用1 H、13 C 和 DEPT 135° NMR 光谱证实了 β-月桂缔的存在。手性 GC 说明了单萜烃的对映体组成,其中 (1 S )-(-)-β-蒎烯、(-)-sabinene 和 (4 S)-(-)-柠檬烯是主要的对映体。本研究首次报道了富含β-月桂烯的博斯瓦利亚精油的精油成分和对映体成分。G. bosvallia精油是 β-月桂烯 的良好来源,β-月桂烯是一种具有广泛生物学特性的化合物。
