INTRODUCTION Modern phytotherapy and quality assurance requires stability data on bioactive metabolites to identify and minimise decomposing factors during processing and storage. A compound's stability in a complex matrix can be different from the stability of the purified compound. OBJECTIVE To test the stability of iridoids and acteoside and quantify changes in colour and microbiological q...

The study tried to explore the role of sugar-residues and mechanisms of phenolic phenylpropanoid antioxidants. Acteoside, along with its apioside forsythoside B and rhamnoside poliumoside, were comparatively investigated using various antioxidant assays. In three electron-transfer (ET)-based assays (FRAP, CUPRAC, PTIO•-scavenging at pH 4.5), the relative antioxidant levels roughly ruled as: act...

Many species belonging to the Scrophularia genus have been used since ancient times as folk remedies for many medical conditions such as scrofulas, scabies, tumors, eczema, psoriasis, inflammations. The aim of this study was to characterize the matrix metalloproteinases (MMPs) inhibitor compounds of the Scrophularia striata extract by bio-guide fractionation. The aerial parts of S. striata were...

Osteoarthritis (OA) is the most common degenerative joint disease with chronic pain caused by progressive degeneration of articular cartilage at synovial joints. Acteoside, a caffeoylphenylethanoid glycoside, has various biological activities such as antimicrobial, anti-inflammatory, anticancer, antioxidative, cytoprotective, and neuroprotective effect. Further, oral administration acteoside hi...

Amyloid beta-peptide (Abeta) has been implicated in the pathogenesis of AD. It can cause cell death in AD by evoking a cascade of oxidative damage to neurons. So antioxidant compounds may throw a light on the treatment of AD. In the present study, we investigated the protective effect of acteoside (AS), an antioxidative phenylethanoid glycoside, on Abeta(25-35)-induced SH-SY5Y cell injury. Expo...

Micellar electrokinetic chromatography (MEKC) conditions were developed to analyze the constituents of Scutellariae Radix (SR) and Scutellaria baicalensis roots. Using the MEKC method, the major flavonoid constituents of baicalin, baicalein and wogonin of wild and cultivated S. baicalensis roots were compared. In a preliminary comparison of electropherogram, one special peak was found in a wild...

The objective of the study was to investigate the effectiveness and efficacy of the randomized, parallel, and controlled trial of Traditional Chinese Medicine, general acteoside of Rehmanniae leaves, compared with piperazine ferulate in the treatment of primary chronic glomerulonephritis. Rehmanniae leaves and piperazine ferulate can reduce proteinuria and erythrocyturia effectively in the trea...
