  Two new sweet oleanene-type triterpene oligoglycosides, named apioglycyrrhizin and araboglycyrrhizin, were isolated from the air-drie root of Glycyrrhiza inflata [Chinese Glycyrrhizae Radix, Shinkyo-kanzo in Japanese], and their structures have been determined on the basis of chemical and physicochemical evidence.

  GC-FID and GC-MS analyses of methyl derivatives, MALD-TOF-MS measurements and NMR spectra were used to confirm the structural characteristics of the isomers. The (1)H and (13)C NMR signals of each isomer saccharide were assigned using COSY, E-HSQC, HSQC-TOCSY, HMBC and H2BC techniques. These kestose isomers were identified as α-D-fructofuranosyl-(2- > 2)-α-D-glucopyranosyl-(1 < ->2)-β-D-fructofuranoside

  通过碳-塞利特柱色谱法和HPLC从甜菜糖蜜中分离出八种KestOSe异构体。甲基衍生物的GC-FID和GC-MS分析，MALD-TOF-MS测量和NMR光谱用于确认异构体的结构特征。使用COSY，E-HSQC，HSQC-TOCSY，HMBC和H2BC技术分配每种异构体糖的（1）H和（13）C NMR信号。这些异构体被鉴定为α-D-果糖呋喃糖基-（2-> 2）-α-D-吡喃葡萄糖基-（1 <-> 2）-β-D-果糖呋喃糖苷，α-D-果糖呋喃糖基-（2-> 3 ）-β-D-果糖呋喃糖基-（2 <-> 1）-α-D-吡喃葡萄糖苷，α-D-果糖呋喃糖基-（2-> 4）-β-D-果糖呋喃糖基-（2 <-> 1）-α -D-吡喃葡萄糖苷，β-D-果呋喃糖基-（2-> 4）-β-D-呋喃呋喃糖基-（2 <-> 1）-α-D-吡喃葡萄糖苷，β-D-呋喃呋喃糖基-（2-> 3） -α-D-吡喃葡萄糖基-（1

  Three triterpenoid saponins, gymnocladus saponins A (12), B (18) and C (20), were isolated from the fruits of Gymnocladus chinensis BAILLON (Leguminosae). On the basis of chemical and physicochemical evidence, these saponins were characterized as 2β, 23-dihydroxy-3-O-[α-L-arabinopyranosyl (1→6)-β-D-glucopyranosyl] acacic acid 28, 21-lactone (12), 2β, 23-dihydroxy-3-O-[β-D-glucopyranosyl (1→2)-β-D-glucopyranosyl] acacic acid 28, 21-lactone (18) and 2β, 23-dihydroxy-3-O-[β-D-xylopyranosyl (1→2)-α-L-arabinopyranosyl (1→6)-β-D-glucopyranosyl] acacic acid 28, 21-lactone (20).

  从中华金雀花（Gymnocladus chinensis BAILLON，豆科）果实中分离出三种三萜皂苷，分别是金雀花皂苷A (12)、B (18)和C (20)。根据化学和物理化学的证据，这些皂苷被表征为：2β, 23-二羟基-3-O-[α-L-阿拉伯糖吡喃糖（1→6）-β-D-葡萄糖吡喃糖] 酸性28, 21-内酯 (12)；2β, 23-二羟基-3-O-[β-D-葡萄糖吡喃糖（1→2）-β-D-葡萄糖吡喃糖] 酸性28, 21-内酯 (18)；和2β, 23-二羟基-3-O-[β-D-木糖吡喃糖（1→2）-α-L-阿拉伯糖吡喃糖（1→6）-β-D-葡萄糖吡喃糖] 酸性28, 21-内酯 (20)。

  The chemical structures of azukisaponins V (1) and VI (5), two of the six oligoglycosidic ingredients of total azukisaponin isolated from azuki beans, the seeds of Vigna angularis (WILLD.) OHWI et OHASHI (Leguminosae), were investigated. By means of photochemical degradation and chemical analyses, the structures of azukisaponins V and VI were elucidated to be 3-O-[α-L-rhamnopyranosyl (1→2)-β-D-glucopyranosyl (1→2)-β-D-glucuronopyranosyl]-soyasapogenol B (1) and 3-O-[β-D-glucopyranosyl (1→2)-β-D-glucuronopyranosyl]-29-O-[β-D-glucopyranosyl (1→6)-β-D-glucuronopyranosyl] azukisapogenol (5), respectively. Azukisaponin VI (5) is the first reported example of a 3, 29-bisdesmoside of an oleanene oligoglycoside.
