From Hydrangea macrophylla var. Macrophylla, four new secoiridoid glucosides, hydrangenosies A, B, C and D, were isolated, along with the known iridoid glucosides loganin, secologanin, secologanic acid and sweroside. Moreover, hydrangenosides E, F, and G, the glucosides of the same class, were isolated together with hydrangenosides C and D from Hydrangea Scandens. Based on spectroscopic and chemical
来自绣球花。分离了大叶菊,四种新的类蛇皮苷糖苷,绣球菌A,B,C和D,以及已知的鸢尾苷葡糖苷loganin,secologanin,secologanic acid和seroeroside。此外,hydrangenosides E,F,和G,同一类的糖苷,被一起从hydrangenosides C和d分离绣球藤。基于光谱和化学方法,阐明了新的葡糖苷的新结构,该葡糖苷由secologanin和a草酸-丙二酸酯衍生的单元组成,它们通过CC键连接。但是,对其他七种绣球花植物进行了测试,发现它们不包含八仙花苷型糖苷。
