Saponin and sapogenol. XXXI. Chemical constituents of the seeds of Vigna angularis (Willd.) Ohwi et Ohashi. (1). Triterpenoidal sapogenols and 3-furanmethanol .BETA.-D-glucopyranoside.
摘要:
从赤豆(Vigna angularis (Willd.) Ohwi et Ohashi 豆科)种子中分离得到3-呋喃甲醇β-D-吡喃葡糖苷(1)和(+)-儿茶素7-O-β-D-吡喃葡糖苷(3),并确定了它们的结构。从赤豆中还分离得到了总赤豆皂苷混合物。通过酶解、酸解和光化学降解,从总赤豆皂苷中分离出了4种真正的皂苷元,其中包括3种已知的皂苷元:染料木苷元(7)、大豆苷元B(8)、皂土酸(9)和一个新的皂苷元,命名为赤豆皂苷元(10),并阐明了其结构。作为总赤豆皂苷酸解释放的假皂苷元之一,分离得到了一个新的皂苷元,命名为无水染料木苷元(5),并阐明了其结构。
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.
研究了从红豆(Vigna angularis (WILLD.) OHWI et OHASHI)中提取的总红豆皂苷的六种寡糖苷成分中的两种:红豆皂苷V(1)和VI(5)的化学结构。通过光化学降解和化学分析,阐明了红豆皂苷V和VI的结构分别为3-O-[α-L-鼠李糖吡喃基(1→2)-β-D-葡萄糖吡喃基(1→2)-β-D-葡萄糖醛酸吡喃基]-大豆皂苷醇B(1)和3-O-[β-D-葡萄糖吡喃基(1→2)-β-D-葡萄糖醛酸吡喃基]-29-O-[β-D-葡萄糖吡喃基(1→6)-β-D-葡萄糖醛酸吡喃基]红豆皂苷醇(5)。红豆皂苷VI(5)是首次报道的三、二十九双配糖体的鞘脂寡糖苷。

Five azukisapogenol glycosides (1–5) have been isolated from the aerial parts of alsike clover (Trifolium hybridum L.), and their structures were elucidated by combined spectroscopic, spectrometric (1D and 2D NMR; HRESIMS, ESI–MS/MS), and chemical methods. Three of them are new compounds and were identified as 3-O-[-α-l-arabinopyranosyl(1→2)]-β-d-glucuronopyranosyl azukisapogenol (1), 3-O-[-β-d-gl
五次azukisapogenol甙(1 - 5)已经从杂三叶(的地上部分分离杂种车轴草属),和它们的结构经组合的光谱,光谱阐明(1D和2D NMR; HRESIMS,ESI-MS / MS),和化学方法。其中三个是新化合物,分别被确定为3- O -[-α- 1-阿拉伯吡喃糖基(1→2)]-β- d-葡萄糖醛酸吡喃二酚(1),3- O -[-β- d-葡萄糖醛酸吡喃糖基( 1→2)-β- d -glucuronopyranosyl] -27- ö -β- D-吡喃葡萄糖基azukisapogenol(2),和3-ö - [ - α-升-arabinopyranosyl(1→2)-β- d -glucuronopyranosyl] -27- ö -β- D-吡喃葡萄糖基azukisapogenol(3)。剩余的两个(4,5)是已知的化合物,但以前没有被描述为属的皂苷成分车轴。另外,在此属中首次

The present invention pertains to complexes comprising sterols and saponins. The complexes are capable of binding a genetic determinant including a polynucleotide. The complexes may further comprise a lipophilic moiety, optionally a lipophilic moiety comprising a contacting group and/or a targeting ligand, and/or a saccharide moiety. The complexes may further comprise an immunogenic determinant and/or an antigenic determinant and/or a medicament and/or a diagnostic compound. The complexes may in even further embodiments be encapsulated by an encapsulation agent including a biodegradable microsphere. The present invention also pertains to pharmaceutical compositions and methods of treatment of an individual by therapy and/or surgery, methods of cosmetic treatment, and diagnostic methods practised on the human or animal body.
