中文摘要：

目的：通过黔产长裙竹荪鲜品的菌盖、子实体、菌托3部分石油醚提取物的比较研究，为寻找黔产长裙竹荪菌盖、菌托的利用价值、拓展黔产长裙竹荪的合理利用提供科学依据。方法：常温下用石油醚分别对黔产长裙竹荪的3部分进行萃取，应用气质联用仪对萃取的化学成分进行研究，气相色谱柱为HP-Innowax极性柱分离。结果：3部分的石油醚提取物检出69种成分，其中32种成分从竹荪属中检出。菌盖、子实体、菌托3部分的石油醚提取物分别检测出了36、46、31种成分，脂肪酸分别占检出总量的86．15％、84．03％、86．42％，不饱和脂肪酸分别占脂肪酸总检出量的56．00％、65．79％、63．40％。结论：从竹荪属菌盖、子实体的提取物中检出全顺式-10，12-十六碳二烯醛、从竹荪属菌盖的提取物中检出全顺式-9，12，15-十八碳三烯酸。

英文摘要：

Purpose： This study aimed to compare petroleum ether extracts of the pileus, carpophore and volva of Dictyophora indusiata. Methods： The volatile components of the pileus, carpophore and volva of Dictyophora indusiata were extracted with petroleum ether at room temperature （25-30 ℃）, and identified by gas chromatography-mass spectrometry （GC-MS）. The GC column used was HP-Innowax. Results： A total of seventy components were identified from the three petroleum ether extracts of Dictyophora indusiata, among which, thirty-two are first identified from the genus Dictyophora. Thirty-six, forty-seven and thirty-one compounds were identified from the pileus, carpophore and volva, respectively, with fatty acids accounting for 86.15%, 84.03% and 86.42% of the total amounts of detectable compounds, respectively, and unsaturated fatty acid accounting for 56.00%, 65.79%, and 63.40% of the total amount of fatty acids, respectively. Conclusions： Z,Z-IO, 12-hexadecadienal is detected from the pileus and carpophore of Dictyophora indusiata for the first time, and 9,12,15- octadecatrienoic acid, （Z,Z,Z） is detected from the pileus ofDictyophora indusiata for the first time.
