Two new 27-hydroxy-oleanolic acid type triterpenoid saponins, raddeanoside 20 (1) and raddeanoside 21(2) were isolated from the rhizome of Anemone raddeana Regel. The structures of the two compounds were elucidated as 27-hydroxy-oleanolic acid 3-O-alpha-L-rhamnopyranosyl(1-->2) [beta-D-glucopyranosyl (1-->4)]-alpha-L-arabinopyranoside (1) and 3-O-alpha-L-rhamnopyranosyl (1-->2)-alpha-L-arabinopyranosyl-27-hydroxy-oleanolic acid 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranoside (2) on the basis of chemical and spectral evidence.
从毛茛科植物林荫银莲花（Anemone raddeana Regel）的根茎中分离得到两个新的27-羟基齐墩果酸型三萜皂苷，即林荫银莲花苷20（1）和林荫银莲花苷21（2）。基于化学和光谱证据，确定这两个化合物的结构分别为27-羟基齐墩果酸3-O-α-L-鼠李吡喃糖基（1→2）[β-D-吡喃葡萄糖基（1→4）]-α-L-阿拉伯吡喃糖苷（1）和3-O-α-L-鼠李吡喃糖基（1→2）-α-L-阿拉伯吡喃糖基-27-羟基齐墩果酸28-O-α-L-鼠李吡喃糖基（1→4）-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖苷（2）。
