The major toxic constituent of the plant, Wedelia asperrima, is the diterpene aminoglycoside, wedeloside. MS and NMR analysis of the unusually substituted aminoglycosidic portion of wedeloside and comparison with synthetic analogues have permitted the assignment of its structure as a 2 - deoxy - 2 - (3 - methyl - 1 - oxobutyl)amino - 3 - 0 - (1 - oxo - 3 - phenylpropyl) - D - glucopyranoside, β-linked
该植物的主要有毒成分是Wedelia asperrima,是二萜氨基糖苷,即伞形糖苷。MS和NMR分析了麦角甙的异常取代的氨基糖苷部分,并与合成类似物进行了比较,从而可以将其结构指定为2-脱氧-2-(3-甲基-1-氧丁基)氨基-3-0-(1-氧代-3-苯基丙基)-D-吡喃葡萄糖苷,β-连接至二萜糖苷配基。
