  Phenolic glycosides from Kaempferia parviflora

  摘要：

  Three phenolic glycosides were isolated together with two known flavonol glycosides from the H2O-soluble fraction of rhizomes of Kaempferia parviflora. Their structures were determined to be rel-(5aS,10bS)-5a,10b-dihydro-1,3,5a,9-tetrahydroxy-8-methoxy-6H-benz[b]indeno[1,2-d]furan-6-one 5a-O-[alpha-L-rhamnopyranosyl-(1 -> 6)-beta-D-glucopyranoside] (1), its rel-5aS,10bR isomer (2), and (2R,3S,4S)-3-O-[alpha-L-rhamnopyranosyl-(1 -> 6)-beta-D-glucopyranosyl]-3'-O-methyl-ent-epicatechin-(2 alpha -> O -> 3,4 alpha -> 4)-(5aS, 10bS)-5a, 10b-dihydro-1,3,5a,9-tetrahydroxy-8-methoxy-6H-benz[b]indeno[1,2-d]furan-6-one 5a-O-[alpha-L-rhamnopyranosyl-(1 -> 6)-beta-D-glucopyranoside] (3). The structures were elucidated on the basis of analyses of chemical and spectroscopic evidence. (C) 2008 Elsevier Ltd. All rights reserved.

• Oleanane-type triterpenoid saponins from Silene armeria
  作者：Nobuyuki Takahashi、Wei Li、Kazuo Koike

  DOI：10.1016/j.phytochem.2016.07.011

  日期：2016.9

  Twelve triterpenoid saponins, including seven compounds (i.e., armerosides A-G) hitherto unknown, were isolated from whole plants of Silene armeria. Their structures were established based on extensive spectroscopic analyses and chemical methods. From a biosynthetic perspective, C-23 oxidation of the sapogenin appears to be a key factor in the glycosylation pathway.

  从 Silene armeria 的整个植物中分离出 12 种三萜皂苷，包括迄今为止未知的 7 种化合物（即 armerosides AG）。它们的结构是基于广泛的光谱分析和化学方法建立的。从生物合成的角度来看，皂苷元的 C-23 氧化似乎是糖基化途径中的关键因素。
• DETERMINATION OF CONFIGURATION OF MONOSACCHARIDES BY HPLC ON DIASTEREOISOMERIC 1-DEOXY-1-(<i>N</i>-ACETYL-α-METHYLBENZYLAMINO)ALDITOL ACETATES

  Acyclic diastereoisomers, 1-deoxy-1-(N-acetyl-α-methylbenzylamino)alditol acetates, are readily obtained by reductive amination of sugars with chiral α-methylbenzylamine in the presence of sodium cyanoborohydride. Ten pairs of enantiomers of common monosaccharides are resolved by an adsorption HPLC on the diastereoisomers.
