近十年来,国外的药学学者在寻找国与土的宁作用类似的药物时,找到了大戟科的一种植物——一叶荻(Securinega suffruticosa(Pall.)Rehd=S.ramiflora Mull-Arg.)。在其未木化的绿色幼枝和叶中,得到一种生物碱,称为一叶荻碱(securinine),其硝酸盐的作用与硝酸士的宁类似,但毒性较硝酸士的宁弱8～10倍。在1951～1961年间,国外的药学工作者,曾对一叶萩进行了一系列的研究工作,特别是在植物学、化学、药理、临床试验以及农作技术探讨等方面的研究,都已取得一定的成绩;同时为了保证一叶荻碱的高产优质
In the past ten years, foreign pharmacists have found a plant of the family Euphorbiaceae when they are looking for drugs that have a similar effect to the soil in the country: Securinega suffruticosa (Pall.)Rehd=S.ramiflora Mull-Arg .). In its unliganded young shoots and leaves, an alkaloid is obtained, known as a securinine, whose nitrate action is similar to that of strychnine nitrate, but is less toxic than strychnine nitrate. 8 ~ 10 times. In the period from 1951 to 1961, foreign pharmacists had conducted a series of research work on the leafhoppers, especially in the areas of botany, chemistry, pharmacology, clinical trials, and agricultural technology research. Certain results; At the same time in order to ensure the high yield
