Two new triterpenoid saponins, loniceroside A and B, were isolated from the aerial parts of Lonicera japonica. Their structures were established as 3-O-alpha-L-arabinopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl (1-->2)-[beta-D-xylopyranosyl(1-->6)]-beta-D-glucopyranosyl ester and 3-O-alpha-L-rhamnopyranosyl(1-->2)-alpha-L-arabinopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl(1-->2)-[beta-D- xylopyranosyl(1-->6)]-beta-D-glucopyranosyl ester, respectively.
从忍冬的地上部分分离出两种新的三萜皂苷，忍冬皂苷A和忍冬皂苷B。它们的结构分别确定为3-O-α-L-阿拉伯吡喃糖基常春藤皂苷元28-O-α-L-鼠李吡喃糖基（1→2）-[β-D-木吡喃糖基（1→6）]-β-D-葡萄糖吡喃糖基酯和3-O-α-L-鼠李吡喃糖基（1→2）-α-L-阿拉伯吡喃糖基常春藤皂苷元28-O-α-L-鼠李吡喃糖基（1→2）-[β-D-木吡喃糖基（1→6）]-β-D-葡萄糖吡喃糖基酯。
