  • Antibacterial Activity of a New Flavone Glycoside from the Stems of Holmskioldia sanguinea Retz.
    作者:R.N. Yadava、Jyotsna Raghuvansi
    DOI:10.14233/ajchem.2019.22026
    日期:2019.7.7

    A new flavone glycoside was isolated from ethanolic extract of stem parts of Holmskioldia sanguinea Retz. Its structure was characterized as 3,4′-dihydroxy-5,7-dimethoxyflavone-3-O-β-Dgalactopyranosyl(1→4)-O-β-D-arabinopyranosyl-4′-O-α-L-rhamnopyranoside (1) by colour reactions, chemical degradation and spectroscopic analysis. Antibacterial activity of compound 1 was evaluated against various Gram positive and Gram negative bacteria showing a significant effects.

    A novel flavone glycoside was isolated from the methanolic extract of Cynotis axillaris Schult. Various analysis and characterization techniques were used to determine its structure and properties. The compound exhibited a melting point range of 231–232 °C and had a molecular formula of C27H30O14. Several spectral characterization techniques were employed to establish the isolated compound's structure
    从Cynotis axillaris Schult的甲醇提取物中分离出一种新型黄酮苷。使用各种分析和表征技术来确定其结构和性质。该化合物的熔点范围为231-232°C,分子式为C 27 H 30 O 14。采用多种光谱表征技术来建立分离化合物的结构。其中包括紫外-可见光谱、FT-IR、LC-ESI-MS 和 NMR 光谱。基于这些分析,分离的化合物的结构被确定为5,7,4'-三羟基黄酮-8-α-L-吡喃鼠李糖苷-4'-O-β-D-吡喃半乳糖基。该结构表明它是一种黄酮糖苷,由黄酮(5,7,4'-三羟基黄酮)部分在4'位连接至糖分子(吡喃半乳糖基)组成,其在黄酮的8位进一步带有鼠李糖基团。此外,除了结构表征外,该化合物还对多种细菌病原体表现出显着的抗菌功效,包括枯草芽孢杆菌MTCC441等革兰氏阳性菌和大肠杆菌MTCC1098、普通变形杆菌MTCC426和鼠伤寒沙门氏菌MTCC3224等革兰氏
