  • Components of Ether-Insoluble Resin Glycoside (Convolvulin) from Seeds of Quamoclit pennata

    Alkaline hydrolysis of the ether-insoluble resin glycoside (convolvulin) fraction of the seeds of Quamoclit pennata BOJER (Convolvulaceae) provided five new glycosidic acids, quamoclinic acids B, C, D, E, and F, along with six organic acids, isobutyric, 2S-methylbutyric, tiglic, 2R,3R-nilic, 7S-hydroxydecanoic, and 7S-hydroxydodecanoic acids. These new compounds were characterized on the basis of spectroscopic data as well as chemical evidence. Quamoclinic acids E and F are the first examples of heptaglycosides of glycosidic acid.
    对 Quamoclit pennata BOJER(旋花科)种子的醚不溶性树脂苷(convolvulin)部分的碱性水解提供了五种新的苷酸、以及六种有机酸:异丁酸、2S-甲基丁酸、tiglic 酸、2R,3R-nilic 酸、7S-羟基癸酸和 7S-hydroxydodecanoic 酸。这些新化合物的特征是基于光谱数据和化学证据。Quamoclinic 酸 E 和 F 是苷酸七糖苷的第一个例子。
  • Calysepins I–VII, Hexasaccharide Resin Glycosides from <i>Calystegia sepium</i> and Their Cytotoxic Evaluation

    日期:2022.5.27
    Seven new hexasaccharide resin glycosides, named calysepins I–VII (1–7), with 27-membered rings, were obtained from the aerial parts of Calystegia sepium. Their structures with absolute configuration were established on the basis of spectroscopic data interpretation analysis and the use of chemical methods. They were defined as hexasaccharides composed of one d-quinovose, four d-glucose, and one l-rhamnose
    从Calystegia sepium的地上部分获得了七种新的六糖树脂糖苷,命名为 calysepins I-VII ( 1-7 ),具有 27 元环。它们具有绝对构型的结构是在光谱数据解释分析和化学方法的使用的基础上建立的。它们被定义为由一个d-奎诺糖、四个d-葡萄糖和一个l-鼠李糖单元组成的六糖,它们的糖部分在1-7和( 2 R , 3 R )-尼酸1 - 5和7,主要在酰化位置不同。此外,calysepin IV ( 4 ) 对 A549 细胞具有细胞毒性,IC 50值为 5.2 μM。

  • HPLC Isolation and structural elucidation of diastereomeric niloyl ester tetrasaccharides from Mexican scammony root
    作者:Rogelio Pereda-Miranda、Beatriz Hernández-Carlos
    DOI:10.1016/s0040-4020(02)00284-3
    日期:2002.4
    The application of preparative-scale recycling HPLC is illustrated by describing the complete resolution of diastereomeric mixtures of niloyl esters involving both of the (2R,3R) and (2S,3S) enantiomers of 3-hydroxy-2-methylbutanoic acid bonded to a macrocyclic tetrasaccharide from the resin of the Mexican scammony root (Ipomoea orizabensis). The characterization of 13 new diastereomeric niloyl ester glycosides, orizabins IX-XXI, based on the same structure of scammonic acid A was performed by high field NMR spectroscopy. The absolute configuration of the stereogenic carbinol center in the saponification-liberated nilic acid residues esterifying each of the individual pure glycolipids has been determined by careful H-1 NMR analysis of (S)- and (R)-Mosher's ester derivatives.

    Treatment of the crude ether-insoluble resin glycoside (convolvulin) from seeds of Pharbitis nil (Pharbitis Semen), called pharbitin, with indium(III) chloride in methanol provided seven oligoglycosides of hydroxy fatty acid methyl esters partially acylated by 2-methyl-3-hydroxybutyric (nilic) and 2S-methylbutyric acids. Their structures were elucidated on the basis of NMR and MS data and chemical
