Three phenylpropanoid glycosides have been isolated from the methanol extract of Newbouldia laevis roots. One compound is new; its structure has been established by spectroscopic (UV, IR, FAB-MS, 1H and 13C NMR) and chemical methods as 2-(3,4-dihydroxyphenyl)ethyl-O-beta-D-apiofuranosyl-(1-->2)-O-alph a-L- rhamnopyranosyl-(1-->3)-6-O-E-feruloyl-beta-D-glucopyranoside.
从光叶纽苞花根的甲醇提取物中分离出了三种苯丙素苷。其中一种化合物是新的；其结构已通过光谱法（紫外、红外、快原子轰击质谱、1H和13C核磁共振）和化学方法确定为2-(3,4-二羟基苯基)乙基-O-β-D-阿吡喃呋喃糖基-(1→2)-O-α-L-鼠李吡喃糖基-(1→3)-6-O-E-阿魏酰基-β-D-吡喃葡萄糖苷。
