Abstract

Three samples of Boswellia occulta gum resin (Grades I, II and III) were analyzed by GC-MS and GC-FID. Fifty constituents could be identified, and several of them were isolated by flash chromatography and characterized by NMR. The combinatorial synthesis of homologous series of reference constituents permitted the unambiguous identification of five 1-methoxyalkanes and one 1-methoxyalkene. In addition, we measured the C content of one sample of essential oil and of a methoxyalkanes rich fraction and demonstrated that the origin of these materials is totally natural.

摘要

采用 GC-MS 和 GC-FID 对三种乳香树胶树脂（等级 I、II 和 III）样品进行了分析。共鉴定出 50 种成分，其中一些通过快速色谱法分离并通过 NMR 进行了表征。参考成分的同源系列的组合合成允许对 5 种 1-甲氧基烷烃和 1 种 1-甲氧基烯烃进行明确鉴定。此外，我们还测量了一种精油和一种富含甲氧基烷烃的馏分的 C 含量，并证明这些材料的来源完全是天然的。
