The chemical composition of the essential oil from the fruits and leaves of (Lour.) Pers. (Lauraceae) growing wild in Baoshan region, Yunnan Province of China was investigated for the first time in 5.36% and 2.16% (w/w) yields, respectively, when analysed by GC and GC/MS. Ten and 25 components were identified in the fruit and leaf oils which constituted 99.15% and 99.4% of the oils. Of the fruit oil, the major components were neral (36.51%), geranial (44.23%), and citronella (8.77%). The major components of the leaf oil were linalool (67.37%), limonene (6.37%), β-bisabolene (6.03%), neral (5.86%), and caryophyllene oxide (3.20%). The analysis of the essential oil obtained from Baoshan revealed a significant abundance of citral and linalool in the fruits and leaves, respectively. This was the first species to exhibit β-bisabolene as the principal constituent.
首次对中国云南省保山市野生的毛叶木姜子（樟科）果实和叶片精油的化学成分进行了研究。通过气相色谱（GC）和气相色谱 - 质谱联用（GC/MS）分析，果实和叶片精油的得率分别为5.36%和2.16%（w/w）。在果实油和叶油中分别鉴定出10种和25种成分，它们分别占精油的99.15%和99.4%。果实油的主要成分是橙花醛（36.51%）、香叶醛（44.23%）和香茅醛（8.77%）。叶油的主要成分是芳樟醇（67.37%）、柠檬烯（6.37%）、β-红没药烯（6.03%）、橙花醛（5.86%）和氧化石竹烯（3.20%）。对从保山获得的精油分析表明，果实和叶片中分别富含大量的柠檬醛和芳樟醇。这是首次发现以β-红没药烯为主要成分的毛叶木姜子物种。
