曼陀罗(Datura Stramonium Linnaeus)含有莨菪硷(Hyoscyamine),阿托品(Atropine)及东莨菪硷(Scopolamine)等托品衍生类生物硷,其种子含有上述生物硷约0.4％,余为脂肪及硝酸盐等成份。含托品衍生类生物硷都能阻制副交感神经及醋酸胆硷对虹膜和睫状肌的作用,因而使瞳孔放大调节麻痹,故眼科临床常用阿托品及东茛菪硷作散瞳与麻痹调节剂,但由于这两种药物作用剧烈,瞳孔及调节恢复缓慢,故于检查眼底和验光时给患者带来许多不便,因此都用后马托品
Datura Stramonium Linnaeus contains tropine-derived derivatives such as Hyoscyamine, Atropine, and Scopolamine. Its seed contains about 0.4% of the above mentioned biological components, with the remainder being fat and nitrate. And other ingredients. Dermatologically derivatized bioderivatives can inhibit the role of parasympathetic and cholic acid acetate on the iris and ciliary muscles, thereby stimulating pupil dilation and paralysis. Therefore, atropine and diterpenoids are commonly used as ophthalmic dilators and palsy modulators in ophthalmology. , However, due to the severe effects of these two drugs, the pupil and the adjustment recover slowly, so it is inconvenient for the patient to check the fundus and optometry.
