Glucosylated caffeoylquinic acid derivatives from the flower buds of Lonicera japonica
Three new glucosylated caffeoylquinic acid isomers (1-3), along with six known compounds, have been isolated from an aqueous extract of the flower buds of Lonicera japonica. Structures of the new compounds were determined by spectroscopic and chemical methods as (-)-4-O-(4-O-β-d-glucopyranosylcaffeoyl)quinic acid (1), (-)-3-O-(4-O-β-d-glucopyranosylcaffeoyl)quinic acid (2), and (-)-5-O-(4-O-β-d...
متن کاملAllergy-preventive effects of chlorogenic acid and iridoid derivatives from flower buds of Lonicera japonica.
Allergy-preventive activity of flower buds of Lonicera japonica THUNB. was found in the 35% EtOH extract (LJ) using an in vivo assay, The assay system uses monitoring of a decrease in blood flow (BF) in the tail vein of mice subjected to sensitization with hen-egg white lysozyme (HEL). Bioassay-guided fractionation of the 35% EtOH extract led to isolation of chlorogenic acid (1) and three known...
متن کاملA new sesquilignan glucoside from Uraria sinensis.
A new sesquilignan glucoside, urariasinoside A (1), together with eight known compounds, including two lignans, a sesquilignan, a dilignan, and four flavonoid derivatives were isolated from the aerial parts of Uraria sinensis. Their structures were determined on the basis of extensive spectroscopic analyses and comparison with literature data. Compound 1 was evaluated for in vitro cytotoxicity ...

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولIsoconiferoside, a new phenolic glucoside from seeds of Panax ginseng.
A new phenolic glucoside, isoconiferoside (1), was isolated from the seeds of Panax ginseng (Araliaceae). The structure was determined to be 9-O-[β-D-glucopyranosyl-(1 --> 6)-β-D-glucopyranosyl]-trans-coniferyl alcohol based on spectroscopic analyses (1H- and 13C-NMR, DEPT, COSY, HMQC, and HMBC) and acid hydrolysis.
