Two new steroidal saponins were isolated from the fruits of Tribulus terrestris. Their structures were assigned by spectroscopic analysis and colour reaction as 26-O-β-D-glucopyranosyl-(25R)-5α-furostane-12-one-3β,22α,26-triol-3-O-β-D-glucopyranosyl(1 → 4)-β-D-galactopyranoside (1); 26-O-β- D-glucopyranosyl-25(R)-5α-furostan-12-one-3β,22α,26-triol-3-O-α-L-rhamnopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 4)]-β-D-galactopyranoside (2).
从蒺藜果实中分离得到两种新甾体皂甙。通过光谱分析和显色反应，它们的结构被确定为 26-O-β-D-吡喃葡萄糖基-(25R)-5α-呋甾烷-12-酮-3β,22α,26-三醇-3-O-β-D-吡喃葡萄糖基(1 → 4)-β-D-吡喃半乳糖苷（1）；26-O-β-D-吡喃葡萄糖基-25(R)-5α-呋甾烷-12-酮-3β,22α,26-三醇-3-O-α-L-鼠李吡喃糖基-(1 → 2)-O-[β-D-吡喃葡萄糖基-(1 → 4)]-β-D-吡喃半乳糖苷（2）。
