海南皮油沉香挥发性成分分析

Determination of Volatile Constituents of Bark-agarwood in Hainan,China

为了研究皮油沉香挥发性成分的特点,利用气相色谱-质谱联用技术(GC-MS)分析海南省3批不同产地皮油沉香挥发性成分及其相对含量。结果表明:3批沉香中检测到42个色谱峰,其中共有峰12个。文昌产皮油沉香的乙醚提取物倍半萜类成分相对含量较高;而临高和琼海产皮油沉香以2-(2-苯乙基)色酮类成分为主,其乙醚提取物中2-(2-苯乙基)色酮与2-[2-(4-甲氧基苯乙基)]色酮的相对含量之和在奇楠沉香的范围内。

Three bark-agarwood samples were collected from Lingao,Qionghai and Wenchang,Hainan Province to determine their characteristics of volatile constituents. The volatile constituents and relative contents of three bark-agarwood samples were analyzed by GC-MS. From the samples 42 chromatographic peaks were detected,of which 12 peaks were shared by the three samples. The ether extract of bark-agarwood in Wenchang city yielded higher relative content of sesquiterpenes than those in the other two locations,while the major constituents of ether extracts from the bark-agarwood samples in Lingao and Qionghai counties were 2-（2-phenylethyl） chromones,and the sum of the relative content of 2-（2-phenylethyl） chromone and 2-[2-（4-methoxylphenylethyl） ]chromone fell in the range of ether extract of agarwood Borneo kynam.
