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。

Abstract:

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-10,
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 of Dictyophora indusiata for the first time.

Key words: Dictyophora indusiata, petroleum ether extract, gas chromatography-mass spectrometry
