本文报道了水蒸气蒸馏法提取糙叶海棠雌雄鲜叶挥发油的化学成分。分别用GC/MS和GC-FID对挥发油HSMO和HSFO进行了分析。共检测出93种成分，分别占HSMO和HSFO的94.8%和95.3%。HSMO的主要成分为松香芹酮（13.1%），d-大根香叶烯-4-醇（12.6%），1，8-桉叶素（10.8%），-蒎烯（6.4%）和-蒎烯HSFO的主要成分为1，8-桉叶素（20.5%）、芳樟醇（16.5%）、β-蒎烯（15.0%）、β-蒎烯（6.4%）和桧烯（6.3%）。测定了β-蒎烯、桧烯、柠檬烯、芳樟醇在两种精油中的对映体分布。碱性水解后，通过对香豆酸和阿魏酸的核磁共振谱和单萜醇的GC/MS谱的分析，分别鉴定了香豆酸和阿魏酸与顺式菊烯醇（1和4）、顺式菊烯醇（2和5）和顺式松香芹醇（3和6）的非挥发性酯。化合物2、3、5和6是首次在自然界中发现。这些研究结果表明，从化学角度来看，在厄瓜多尔采集的糙皮胡蜂的雄性和雌性个体彼此之间以及与生长在玻利维亚和秘鲁的同一物种的样本之间似乎存在很大差异。
This article reports the chemical composition of the essential oils obtained by hydrodistillation of male and female H.scabrum fresh leaves. The essential oils, HSMO and HSFO, respectively, were analyzed by GC/MS and GC-FID. A total of 93 components were detected, accounting for 94.8% and 95.3% of HSMO and HSFO, respectively. The prevalent constituents of HSMO were pinocarvone (13.1%), d-germacren-4-ol (12.6%), 1,8-cineole (10.8%), -pinene (6.4%), and -pinene (4.8%), whereas the major components of HSFO were 1,8-cineole (20.5%), linalool (16.5%), -pinene (15.0%), -pinene (6.4%), and sabinene (6.3%). The different enantiomeric distribution of -pinene, sabinene, limonene, linalool in the two oils, was determined. The non-volatile esters of p-coumaric and ferulic acids with borneol (1 and 4), cis-chrysanthenol (2 and 5), and cis-pinocarveol (3 and 6) were identified in the leaves after basic hydrolysis and analysis of the NMR spectra of the free acids, and GC/MS spectra of the monoterpene alcohols, respectively. Compounds 2, 3, 5, and 6 have been found in nature for the first time. These findings demonstrated that, from a chemical point of view, male and female individuals of H.scabrum collected in Ecuador seem quite differentiated between each other and from samples of the same species growing in Bolivia and in Peru.
