鹅冠麦角碱为近年新发现的麦角有效成分,其化学分子式为C_(16)H_(18)N_2,熔点198～203℃,旋光度在氯仿溶液中[α]_D~(30)=142,吸收光谱在2825 A.E.附近为最大的吸光度,难溶於水,石油醚,易溶於苯,甲苯,甲醇,乙醚,四氯化炭,乙醇,丙酮,氯仿,醋酸乙脂,吡啶等有机溶剂中。其纯品在乙醚中得柱状结晶,在丙酮中得针状结晶,加水分解则生成物中有麦角酸(lysergic acid)。
Goose-crown ergot alkaloid is an effective component found in recent years. Its chemical formula is C_(16)H_(18)N_2, the melting point is 198~203°C, and the optical rotation is [α]_D~(30)=142 in chloroform solution. Absorption spectrum is the largest absorbance near 2825 AE, insoluble in water, petroleum ether, soluble in benzene, toluene, methanol, ether, carbon tetrachloride, ethanol, acetone, chloroform, ethyl acetate, pyridine and other organic solvents . The pure product was obtained as a columnar crystal in ether, and a needle-like crystal was obtained in acetone. Lysergic acid was found in the product after hydrolysis.
