补充资料:毕扣扣灵碱
分子式:
CAS号:
性质:又称毕扣扣灵(碱),荷包牡丹碱。天然存在的是右旋体。细长片状结晶(由氯仿-甲醇中结晶)。熔点215℃。也有报道熔点177℃。旋光度+130.5°(由氯仿中结晶),pKa4.84。溶于苯、氯仿、醋酸乙酯,微溶于乙醇和乙醚;无色柱状棱晶(由甲醇中结晶),熔点195℃,旋光度+123°(c=3.58,氯仿)。易溶于氯仿,不易溶于乙醚、丙酮及乙醇中,能溶于热的苛性碱中。存在于罂粟科植物土延胡(Corydalishumosa Migo)的块茎中,化学合成可得到其外消旋体。具有兴奋子宫作用。具有强烈的致惊厥作用,且发作快、持续时间短,有可能用作癫痫的诊断用药。
