"Magic mushrooms" is the most common name given to hallucinogenic fungi containing the psychoactive alkaloids psilocybin and psilocin. In recent years, fungis' sclerotia, commonly called "magic truffles" have become a form of supply of psychoactive Psilocybe alkaloids since Psilocybe sclerotia are not specifically included in the laws banning the sale, the purchase and the use of such substances and mushrooms containing them. A liquid chromatography -tandem mass spectrometry (LC-MS/MS) method was developed for the rapid determination of psilocybin and psilocin in Psilocybe sclerotia. Following a simple step extraction with methanol, the alkaloids were separated on a reversed-phase column using a gradient of 0.1% formic acid - acetonitrile s a mobile phase at a flow rate of 0.2 mL/min.. Separated analytes were detected by electrospray ionization tandem mass spectrometry in the positive ion mode using multiple reaction monitoring. The developed method was linear over the calibration range for all two substances under investigation, with a r(2) > 0.99. The detection and quantification limits were 0.3 µg and 1 µg per 100 mg truffles, for both psilocin and psilocybin and the intra- and inter-day coefficients of variation were always better than 15%. Using this method, the presence of only psilocybin was demonstrated in examined Psilocybe sclerotia. The content of psilocybin was found to vary over a concentration range of 59.3 to 167.8 µg per 100 mg of fresh sclerotia.
“迷幻蘑菇”是最常见的名称,用于含有致幻生物碱裸盖菇素和赛洛西宾的致幻真菌。近年来,真菌的菌核,通常称为“迷幻蕈菌”,已经成为一种供应致幻裸盖菇素的形式,因为裸盖菇素菌核不在禁止销售、购买和使用这些物质以及含有这些物质的蘑菇的法律范围内具体包括。开发了一种用于快速测定迷幻蕈菌菌核中裸盖菇素和赛洛西宾的液相色谱-串联质谱(LC-MS/MS)方法。用甲醇进行简单的一步提取后,用 0.1%甲酸-乙腈作为流动相,在 0.2mL/min 的流速下在反相柱上分离生物碱。用电喷雾串联质谱在正离子模式下,通过多反应监测对分离的分析物进行检测。该方法在所有两种被调查物质的校准范围内均呈线性,相关系数(r²)均大于 0.99。检测限和定量限均为 0.3μg 和 1μg/100mg 蕈菌,裸盖菇素和赛洛西宾均如此,日内和日间变异系数始终小于 15%。使用该方法,仅证明了检查的迷幻蕈菌菌核中存在裸盖菇素。发现裸盖菇素的含量在 59.3 至 167.8μg/100mg 新鲜菌核的浓度范围内变化。
