为探究鹿花菌属Gyromitra Fr.真菌的毒性,对采自新疆和贵州的4种鹿花菌属真菌进行鉴定,并利用液相色谱-串联质谱联用仪(LC-MS/MS)对鹿花菌属真菌进行23种邻苯二甲酸酯(PAEs)类化合物的检测及含量测定.经鉴定4种鹿花菌分别为大鹿花菌G.gigas、球孢鹿花菌G.sphaerospora、毒鹿花菌G.venenata和新疆鹿花菌G.xinjiangensis.检测结果表明:在4种鹿花菌属真菌中检出邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二(2-乙基己基)酯(DEHP)3种有毒有害化合物,其中大鹿花菌、新疆鹿花菌和毒鹿花菌中含有DBP、DIBP、DEHP,球孢鹿花菌中含有DBP、DIBP.4种鹿花菌属真菌中所含的PAEs类化合物均超过我国规定的最大限量.研究结果提供了4种鹿花菌属标本宏观和微观特征的详细描述,补充了本属物种的部分形态特征,通过检测邻苯二甲酸酯类化合物,为鹿花菌属物种的毒性研究提供了新的思路.
Species Identification and Content Determination of Phthalate Esters for Four Strains of Gyromitra
To investigate the toxicity of Gyromitra Fr.,species identification for four strains of Gyromitra collected respectively from Xinjiang and Guizhou of China were conducted.Our results showed that they belonged to different species of G.gigas,G.sphaerospora,G.venenata and G.xinjiangensis.Liquid chromatography-tandem mass spectrometry(LC-MS/MS)was used for the detection and quantification of 23 types of phthalate esters(PAEs)compounds in the above four fungal species of Gyromitra.Three toxic and harmful compounds,dibutyl phthalate(DBP),diisobutyl phthalate(DIBP),and di(2-ethylhexyl)phthalate(DEHP),were detected from the four species of Gyromitra.Among them,DBP,DIBP,and DEHP were found in G.gigas,G.xinjiangensis,and G.venenata,while DBP and DIBP were found only in G.sphaerospora.Notably,contents of PAEs compounds detected within all of the four species of Gyromitra exceeded the level of maximum limits from the Chinese regulation standards.The present study gives the detailed descriptions of macroscopic and microscopic characteristics and contents of various types of phthalate ester compounds for the four Gyromitra specimens,which thereafter not only complements the information of morphological features but also provides new insights for the toxicity research of Gyromitra species.
