【中文摘要】 用抑酶法測(cè)定灰花紋鵝膏(Amanita fuliginea)子實(shí)體內(nèi)的毒素,結(jié)果表明,灰花紋鵝膏菌所含毒素與毒鵝膏(Amanita Phalloides)所含毒素相近。小白鼠肌肉注射毒性試驗(yàn)表明,每只小白鼠注射1ml濃度為0.05g/ml的灰花紋鵝膏菌子實(shí)體水提液,6h內(nèi)被測(cè)小白鼠全部死亡;若注射濃度在0.01g/ml以下,小白鼠有中毒癥狀而無(wú)死亡,說明該菌是一種劇毒鵝膏菌。

【英文摘要】 The toxin of Amanita fuliginea fruitbodies was measured with enzyme inhibition method designed on the principle that α-amanitin inhibited the activities of eukaryotic RNA polymerase Ⅱ. The results showed that the toxin constituent of A. fuliginea was similar to that contained in A. phalloides. Toxicity tests carried out by intramuscular injection with A. futiginea fruitbody extract into murine showed that all the murine died in six hours after being injected with 1ml of the extract at the concentration of 0.05g/ml showing obvious intoxicating symptoms, while none of the murine died if the concentration of the extract was below 0.01g/ml. So it was concluded that A . fuliginea was a very poisonous species of the Amanita .
