Two novel triterpene glycosides have been isolated from Mimosa pigra. The aglycone of these two compounds was identified as machaerinic acid by 1H- and 13C-nmr spectroscopy and by comparison with an authentic sample. This aglycone is substituted at position C-3 by an identical oligosaccharide chain in these glycosides, and at position C-21 by either a Z/E-methoxycinnamic [1] unit or an E-cinnamic acid [2] unit.
从含羞草中分离出了两种新型三萜糖苷。通过¹H-和¹³C-核磁共振光谱并与标准样品比较,确定这两种化合物的苷元为玛卡瑞尼酸。在这些糖苷中,该苷元在C-3位被相同的寡糖链取代,在C-21位则被一个Z/E-甲氧基肉桂酸[1]单元或一个E-肉桂酸[2]单元取代。
