山茛菪碱系从茄科植物唐古特山茛菪中提取的一种生物碱。天然品为654—1,合成品为654—2。与阿托品、樟柳碱等均以托品环与托品酸酯化而成母体结构,同属托品类生物碱。与阿托品有共同的药理性质。但654—2在托品环上少一氧桥,多一羟基,则其不易透过血脑屏障,中枢抑制和中枢兴奋作用较阿托品为弱,抑制腺体分泌和扩瞳作用为阿托品的1/15左右。解痉作用的选择性 Anisodamine is an alkaloid extracted from the solanaceae Tanggutanculus. Natural product is 654-1, synthetic product is 654-2. And atropine, anisodine and so on are supporting the Central and Tropsch esterified from the parent structure, both belong to the care products alkaloids. And atropine have common pharmacological properties. However, 654-2 is less anaerobic bridge on the support ring, more than a hydroxyl, then it is not easy to cross the blood-brain barrier, central inhibitory and central stimulant effect is weaker than atropine, inhibition of glandular secretion and dilated effect of atropine 1 / 15 or so. Selective antispasmodic effect
