摘要
采用乙醚浸提法提取了4种奇楠沉香样品(海南产白奇楠、海南产紫奇楠、海南产绿奇楠和越南产绿奇楠),4个样品的得率分别为:20.3％、27.6％、48.0％、40.2％.应用气相色谱-质谱联用(GC-MS)技术分析测定4个样品乙醚提取物的化学成分及相对含量,从4种奇楠沉香中共鉴定了37个化合物,其中倍半萜类化合物共20个,据报道有香味描述的有7个;2-(2-苯乙基)色酮类化合物11个,在海南产白奇楠、海南产紫奇楠、海南产绿奇楠和越南产绿奇楠乙醚提取物中相对含量分别达到74.55％、95.59％、93.90％、89.57％,其中,化合物2-(2-苯乙基)色酮和化合物2-[2-(4-甲氧基苯)乙基]色酮在这4种奇楠中相对含量之和分别达到了66.47％、82.09％、84.71％、71.98％.结果表明,奇楠沉香乙醚提取物中含少量的多种骨架类型的芳香倍半萜,富含2-(2-苯乙基)色酮类化合物,特别是化合物2-(2-苯乙基)色酮与2-[2-(4-甲氧基苯)乙基]色酮.
Abstract
Four types of agarwood "Qi-Nan" (Bai Qi-Nan,Zi Qi-Nan,Lv Qi-Nan from Hainan,China,and Lv Qi-Nan from Vietnam) were extracted with ether and the yields of the four types of agarwood "Qi-Nan" were 20.3％,27.6％,48.0％ and 40.2％,respectively.The chemical constituents and relative contents of the ether extracts of the four were analyzed by gas chromatography-mass (GC-MS) spectrometry and thirty-seven compounds including twenty sesquiterpenes and eleven 2-(2-phenylethyl)chromone derivatives were identified finally.Seven of the sesquiterpenes were reported to be fragrant.The relative content of 2-(2-phenylethyl)chromone derivatives in the ether extracts of Bai Qi-Nan,Zi Qi-Nan,Lv Qi-Nan from Hainan province and Lv Qi-Nan from Vietnam were 74.55％,95.59％,93.90％ and 89.57％,respectively.The relative content of two compounds 2-(2-phenylethyl)chromone and 2-[2-(4-methoxyphenyl)ethyl]chromone accounted for 66.47％,82.09％,84.71％,71.98％,respectively,in the ether extracts of the four.The results indicated that in the ether extracts of agarwood "Qi-Nan",there existed relative small amount of fragrant sesquiterpenes with different carbon skeletons and large amount of 2-(2-phenylethyl)chromone derivatives,especially compounds 2-(2-phenylethyl)chromone and 2-[2-(4-methoxyphenyl)ethyl] chromone.
