摘要： 桑品种龙桑一号(Morus alba)栽培于中国东北黑龙江省齐齐哈尔市甘南林场桑产业科技示范园。2009年7月、8月和9月的桑品种龙桑一号干桑叶精油中的挥发性组分经水蒸馏提取后进行了气相色谱-质谱（GC-MS）分析。结果表明桑叶精油的共有组分是植醇（醇类化合物）、六氢金合欢丙酮（酮类化合物）、二十七烷和二十五烷（烃类化合物）。棕榈酸为7月和8月采集桑品种龙桑一号干桑叶精油的共有第一主成分。顺式-β-金合欢烯、反式-β-金合欢烯、β-甜没药烯、反式-α-佛手柑油烯和α-姜黄烯是9月采集桑品种龙桑一号干桑叶精油的主要芳香组分。萜类化合物相对含量较高的9月份采集的干桑叶精油具有药用价值。

Abstract: The mulberry variety “Longsang 1” (Morus alba) was cultivated in Gannan Forest Mulberry Industry Science and Technology Demonstration Field of the Qiqihar City in Heilongjiang Province in Northeastern China. In July,August and September of 2009, the leaves of “Longsang 1” were collected, then the volatile components of the essential oils in the leaves were hydrodistillated and analyzed by gas chromatography-mass spectrometry.The results showed that phytol (alcohols),hexahydrofamesyl acetone (ketones),heptacosane,and pentacosane (hydrocarbons) were the common volatile components of the essential oil.Hexadecanoic acid was dominant in the essential oil from leaves collected in July and August. (E)-β-farnesene,(Z)-β-farnesene,β-bisabolene,trans-α- bergamotene and α-curcumene were the main volatile flavor compounds in the essential oil from leaves collected in September. Air-dried mulberry leaves collected in September has relatively high medicinal value due to their higher content of terpenoids in the essential oil.

Key words: Morus alba, essential oil, hexadecanoic acid, terpenoids, gas chromatography-mass spectrometry
