千金藤素(Cepharanthine)系从防已科植物千金藤(Stephania cepharantha Hayata)的根茎中分离而得一种双乌药硷型(Biscoclaurine)双苄基异喹啉类生物硷,我国赵燏黄氏于1948年亦曾获得同一生物硷。其游离硷熔点145～155℃,比旋度〔α〕_D~6+351°(氯仿)。千金藤素的生理作用是多方面的,它具有解毒,抗过敏,抗麻疯,抗结核杆菌等多种作用。在四十年代曾用千金藤素治疗结核病,并发现结核病患者,在服用千金藤素后,外周血液中有白细胞增多的现象,从而引起了千金藤素防治白细胞减少症的研究。实验研究:正常小鼠,连续七天给予千 Cepharanthine was isolated from the roots of Stephania cepharantha Hayata, a Biscoclaurine bis-benzylisoquinoline alkaloid, The same alkalinity was also obtained in 1948. The free base melting point of 145 ~ 155 ℃, specific rotation [α] _D ~ 6 +351 ° (chloroform). Celanthin physiological effect is multifaceted, it has detoxification, anti-allergy, anti-leprosy, anti-tuberculosis and many other effects. In the forties had cepharanthine treatment of tuberculosis, and found that patients with tuberculosis, taking cetitetuin, the peripheral blood leukocytosis, which led to cepharanthine leukopenia research. Experimental study: Normal mice, given thousands of consecutive seven days
