Two new flavonoids, 5,8-dihydroxy-4'-methoxy-6,7-methylenedioxyisoflavone and carthamidin-7-O-alpha-L-rhamnopyranoside and a new triterpenoid saponin, 3 beta,16 beta,22 beta,24-tetrahydroxy-olean-12- ene-3-beta-yl-]beta-D-glucopyranosyl (1-->2)]-alpha-L-rhamnopyranoside (junceoside), were isolated from Spartium junceum. Their structures were elucidated by means of IR, UV, MS, 1H, 13C NMR, 13C NMR DEPT and 2D NMR experiments. Apigenin-7-O-beta-D-glucopyranoside and genistein-8-C-beta-D-glucopyranoside, never previously found in this plant, were also isolated.
从鹰爪豆中分离出两种新黄酮类化合物，5,8 - 二羟基 - 4'- 甲氧基 - 6,7 - 亚甲二氧基异黄酮和红花苷元 - 7 - O - α - L - 鼠李吡喃糖苷，以及一种新的三萜皂苷，3β,16β,22β,24 - 四羟基 - 齐墩果 - 12 - 烯 - 3 - β - 基 - [β - D - 吡喃葡萄糖基(1→2)] - α - L - 鼠李吡喃糖苷（鹰爪豆皂苷）。通过红外光谱（IR）、紫外光谱（UV）、质谱（MS）、1H、13C核磁共振（NMR）、13C NMR DEPT和二维核磁共振（2D NMR）实验对其结构进行了阐明。还分离出了芹菜素 - 7 - O - β - D - 吡喃葡萄糖苷和染料木素 - 8 - C - β - D - 吡喃葡萄糖苷，这两种化合物此前从未在该植物中发现过。
