Two new triterpene glycosides, 24-deoxyoxytrogenin 3-O-α-L-rhamnopyranosyl (1→2)[β-D-glucopyranosyl]-β-D-galactopyranosyl (1→2)-β-D-glucuronopyranoside and sophoradiol 3-O-α-L-rhamnopyranosyl (1→2)-β-D-glucuronopyranosyl (1→2)-β-D-glucuronopyranoside with four known glycosides were isolated from a Chinese natural medicine, the roots of Uraria crinita (L.) DESV. Their structures were determined by chemical and spectral methods.
从中国天然药物假地蓝（Uraria crinita (L.) DESV.）的根中分离得到了两种新的三萜糖苷，即24-脱氧氧代洋地黄毒苷元3-O-α-L-鼠李吡喃糖基（1→2）[β-D-吡喃葡萄糖基]-β-D-吡喃半乳糖基（1→2）-β-D-吡喃葡萄糖醛酸苷和槐二醇3-O-α-L-鼠李吡喃糖基（1→2）-β-D-吡喃葡萄糖醛酸苷基（1→2）-β-D-吡喃葡萄糖醛酸苷，以及四种已知糖苷。通过化学和光谱方法确定了它们的结构。
