The protective effect of an iridoid catalpol extracted and purified from the traditional Chinese medicinal herb Rehmannia glutinosa on the neuronal degeneration of nigral-striatal dopaminergic pathway was studied in a chronic 1-methyl-4-phenyl-1,2,3,4-tetrahydropyridine (MPTP)/probenecid C57BL/6
Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common age-related neurodegenerative disorders, affecting several millions of aged people globally. Among these disorders, AD is more severe, affecting about 7% of individuals aged 65 and above. AD is primarily a dementia-related
rTg4510 mice are transgenic mice expressing P301L mutant tau and have been developed as an animal model of tauopathy including Alzheimer's disease (AD). Cornel iridoid glycoside (CIG) is an active ingredient extracted from Cornus officinalis, a traditional Chinese herb. The purpose of BACKGROUND Chondrocyte dysfunction and apoptosis are 2 major features during the progression of osteoarthritis. Catalpol, an iridoid glycoside isolated from the root of Rehmannia, is a valuable medication with anti-inflammatory, anti-oxidative, and anti-apoptotic effects in various diseases.
BACKGROUND
Picrorhiza kurroa Royle (Scrophulariaceae) is an important medicinal herb being widely used in variety of ailments.
OBJECTIVE
The present study was envisaged to evaluate the effects of iridoid glycosides enriched fraction (IGs) from Picrorhiza kurroa rhizome against cyclophosphamide (CP)
Valeriana jatamansi Jones, a plant with heart-shaped leaves in the Valeriana genus of Valerianaceae, is widely used in Chinese folk medicine. Iridoid is an important constituent of V. jatamansi that contributes to the pharmacological efficacy of the herb. This study aims to investigate the
Valeriana jatamansi is widely used in Chinese folk medicine and contains iridoids as important active ingredients. The brain-gut axis describes a complex bidirectional system between the central nervous system and the gastrointestinal tract. Herein, we evaluated the antidepressant effects of
The purpose of this work is to study the effect of catalpol, an iridoid from Rehmannia glutinosa on neurodegenerative changes induced by beta-amyloid peptide Abeta(25-35) or Abeta(25-35)+ibotenic acid and the underlying mechanism. Results showed that catalpol significantly improved the memory
Eucommia ulmoides has been used for many years as a successful strategy to treat male infertility. Aucubin (AU) is the active ingredient extracted from Eucommia ulmoides. However, its protective action and exact mechanism on testicular injury is not yet Corni Fructus (CF), the red fruit of Cornus officinalis Siebold & Zucc, has been used both as food and medicinal herb in traditional Chinese medicine (TCM). Loganin is a major iridoid glycoside and one of the quality control indexes of CF. In TCM clinical practice, prescription Polyphenols exert beneficial effects on vision. We hypothesized that polyphenol components of Vaccinium uliginosum L. (V.U.) extract protect retinal pigment epithelial (RPE) cells against blue light-induced damage. Our aim was to test extracts containing polyphenol components to ascertain effects to
OBJECTIVE
To observe the protective effects of the Huanglian Jiedu decoction aqueous extract and its active fraction, which consists of total alkaloids, total flavonoids and total iridoid, on the thalamus of cerebral ischemia in rats.
METHODS
The rat model of middle cerebral artery occlusion (MCAO)
Reducing sugars can react non-enzymatically with amino groups of proteins and lipids to form irreversibly cross-linked macroprotein derivatives called as advanced glycation end products (AGEs). Cross-linking modification of extracellular matrix proteins by AGEs deteriorate their tertiary structural
The hepatoprotective activity of Picroliv, a standardized iridoid glycoside fraction of Picrorhiza kurroa, has been investigated by studying the protection of biochemical and histological changes induced in livers of rats given single oral doses (7 mg/kg) of aflatoxin B1. Administration of aflatoxin
Geraniol 10-hydroxylase (G10H) is a cytochrome P450 monooxygenase involved in the biosynthesis of iridoid monoterpenoids and several classes of monoterpenoid alkaloids found in a diverse range of plant species. Catharanthus roseus (Madagascar periwinkle) contains monoterpenoid indole alkaloids,
