Iridoid glycoside-based quantitative chromatographic fingerprint analysis: a rational approach for quality assessment of Indian medicinal plant Gambhari (Gmelina arborea).
A sensitive, selective and robust qualitative and quantitative densitometric high-performance thin layer chromatographic method was developed and validated for the determination of iridoid glycoside in the aerial part of Gambhari (Gmelina arborea). Iridoid gycoside 6-O-(2'',3''-dibenzoyl)-alpha-l-rhamnopyranosylcatalpol (IG) was used as a chemical marker for the standardization of G. arborea pl...
متن کاملIridoid and Caffeic Glycoside Ester from the Leaf And Stem of Stachytarpheta Angustifolia (Mill) Vahl Verbenaceae
Two glycosides were isolated from the n-Butanol soluble portion of the ethanolic portion of the stem and leaves part of stachytarpheta angustifolia. Their structures were elucidated as Iridoid glycoside (1) and a caffeic glycoside ester named as –β(3 1 , 4 1 dihydroxyphenyl)–ethyl-O-α-L-rhamnopyranosyl-(1-3)-β-D-(4-O-Caffeoyl) glucopyranoside (2) by spectroscopic Method.
متن کاملFlavonol glycosides and novel iridoid glycoside from the leaves of Morinda citrifolia.
One new iridoid glycoside and five known flavonol glycosides have been isolated from the leaves of Morinda citrifolia. The new iridoid exists as an epimeric mixture in solution. Complete assignments of the proton and carbon chemical shifts for the individual epimers were accomplished on the basis of high-resolution 1D and 2D NMR data. Their antioxidative activities were measured. All of these c...
متن کاملCornel iridoid glycoside improves memory ability and promotes neuronal survival in fimbria-fornix transected rats.
Cornel iridoid glycoside (CIG) is a main component extracted from a traditional Chinese herb Cornus officinalis. Our previous study found that CIG improved neurological function in cerebral ischemic rats. The aim of this study was to investigate the therapeutic benefit of CIG in rats with fimbria-fornix transection (FFT) and explore the underlying molecular mechanisms. CIG (20, 60 and 180 mg/kg...
متن کاملCornel Iridoid Glycoside Improves Locomotor Impairment and Decreases Spinal Cord Damage in Rats
Purpose. This study was to investigate the effects of cornel iridoid glycoside (CIG) on spinal cord injury (SCI) in rats. Methods. The thoracic cord (at T9) of rats was injured by clip compression for 30 sec. Locomotor function was assessed using the Basso, Beattie, and Bresnahan (BBB) rating scale. Neuroanatomic stereological parameters as well as Nogo-A, p75 neurotrophin receptor (p75NTR), an...
