从越南山小桔的叶中分离得到2个新 的喹唑啉类生物碱,分别为glycozolone-A和B,运用光谱方法对其结构进行了鉴定。 越南山小桔于燥叶410g用丙酮室温提取,提取物经硅胶柱层析,分别用己烷、己烷-丙酮(8:1,4:1,2:1,1:2)、丙酮和甲醇依次洗脱,分作8部分,其中 Two new quinazoline alkaloids, glycozolone-A and B, were isolated from the leaves of Vicia virens, and their structures were identified by spectroscopic methods. The Viet Nam small orange was dried at room temperature with acetone and extracted with acetone at room temperature. The extract was chromatographed on silica gel with hexane, hexane-acetone (8:1, 4:1, 2:1, 1:2), acetone and The methanol was eluted in order and divided into 8 parts.
