Abstract

The leaf essential oils of five Desmos species from Vietnam have been extracted by steam distillation and subjected to GC and GC-MS analyses. The plant samples were Desmos cochinchinensis Lour., D. penduculosus (A. DC.) Ban, D. penducolosus var. tonkinensis Ban, D. chinensis Lour., and D. dumosus (Roxb.) Saff. The oils were rich in sesquiterpene hydrocarbons (65.9%-88.9%) and monoterpene hydrocarbons (6.3%-30.9%). The oxygenated counterparts were less common. The quantitatively significant constituents of the oils were alpha-pinene (2.4%-12.1%), beta-elemene (2.2-39.5%), beta-caryophyllene (13.9-26.3%), germacrene D (9.9-15.5%), bicyclogermacrene (2.0-11.4%) and alpha-humulene (3.8-7.5%). The studied oils could be classified into two chemical forms: oils with abundance of beta-caryophyllene, germacrene D and alpha-pinene (D. cochinchinensis, D. penducolosus var. tonkinensis, D. chinensis and D. Dumosus) and oil with high amounts of beta-elemene, beta-caryophyllene and germacrene D (D. penduculosus).

摘要

采用水蒸气蒸馏法提取了越南五种假鹰爪属植物的叶精油，并对其进行了气相色谱（GC）和气相色谱 - 质谱联用（GC - MS）分析。植物样本分别为毛叶假鹰爪、长柄假鹰爪、东京长柄假鹰爪、假鹰爪和髯毛假鹰爪。这些精油富含倍半萜烃（65.9% - 88.9%）和单萜烃（6.3% - 30.9%）。含氧化合物相对较少。这些精油中含量具有定量意义的成分有α - 蒎烯（2.4% - 12.1%）、β - 榄香烯（2.2 - 39.5%）、β - 石竹烯（13.9 - 26.3%）、吉马烯D（9.9 - 15.5%）、双环吉马烯（2.0 - 11.4%）和α - 葎草烯（3.8 - 7.5%）。所研究的精油可分为两种化学类型：富含β - 石竹烯、吉马烯D和α - 蒎烯的精油（毛叶假鹰爪、东京长柄假鹰爪、假鹰爪和髯毛假鹰爪）以及富含大量β - 榄香烯、β - 石竹烯和吉马烯D的精油（长柄假鹰爪）。
