A NEW alkaloid has been isolated by us in the crystalline form from the leaves of Adhatoda vasica Nees (Indian Patent No. 62349 of November 21, 1957. Patent application No. 64603 of July 9, 1958). The alkaloid, which has been named vasicinone, has been found to be a much weaker base than vasicine, an alkaloid which is already known to be present in this plant. Elementary analysis gave, C = 65.33, H
我们已从 Adhatoda vasica Nees 的叶子中以结晶形式分离出一种新的生物碱(1957 年 11 月 21 日的印度专利第 62349 号。1958 年 7 月 9 日的专利申请第 64603 号)。已经发现这种被命名为 vasicinone 的生物碱比 vasicine 弱得多,后者是一种已知存在于这种植物中的生物碱。元素分析得出,C = 65.33,H = 4.93,N = 13.65%。发现分子量 (Rast) 约为 210,分子式为 C11H10N2O2。发现该生物碱与 2,3-(α-羟基三亚甲基)-4 喹唑酮相同,后者是早先通过用 30% 过氧化氢氧化 vasicine1,2 制备的。
