摘要: 穿心莲内酯亚硫酸氢钠加成物的结构,根据元素分析、紫外、红外、核磁共振和质谱所提供的数据,确定为(Ⅱ),其名称为14-脱羟-13-脱氢穿心莲内酯-12-磺酸钠盐(14-dehydroxyl-13-dehydroandrographolide-12-sulfonic acid sodium salt)。Abstract: The structure of the adduct of andrographolide with sodium hydrogen sulfite was established as (Ⅱ) by means of data analyses of MS, NMR, IR, UV and elementary analysis. The adduct is named 14-dehydroxyl-13-dehydroandrographolide-12-sulfonic acid sodium salt.
