Introduction Reactive oxygen species (ROS) have been shown to play a critical role in many diseases such as diabetes mellitus, cancer, Alzheimer, arteriosclerosis and other conditions. Chronic glucose levels in blood or cells of diabetic patients are known to cause oxidative damages, followed by an increasing in ROS production and/or dysfunction of antioxidant defense system (enzyme or non-enzy...

BACKGROUND Inflammatory bowel diseases (IBD), which include ulcerative colitis (UC) and Crohn's disease (CD), are debilitating and chronic disorders with unpredictable courses and complicated treatment measures. Therefore, an efficient treatment protocol seems necessary as therapeutic prophylaxis for these disorders.This study aims to determine the healing effect of Teucrium polium (T. polium) ...

Recently, there is growing interest in finding naturally occurring antioxidants for use in foods or medicinal materials to replace synthetic antioxidants, which are being restricted due to their carcinogenicity [1]. Antioxidants are secondary constituents or metabolites found naturally in plants. They are mainly phenolics serving in plant defense mechanisms to counteract reactive oxygen species...

A new ursane-type triterpenoid, 3β-hydroxy-urs-30-p-Z-hydroxycinnamoyloxy-12-en-28-oic-acid (1), together with three known triterpenoids, 3β-hydroxy-urs-30-p-E-hydroxycinnamoyloxy-12-en-28-oic-acid (2), 2α,3β,19α-trihydroxy-urs-12-en-28-oic-acid (3), and ursolic acid (4), four known lignans, pinoresinol (5), 9α-hydroxypinoresinol (6), (+)-medioresinol (7), and (+)-kobusin (8), and two steroids,...

Some plant extracts showed the ability to retard the diffusion of glucose across the dialysis tube. The present study was designed to investigate the effect of aqueous and ethanolic extracts of Teucrium polium (T. polium) on glucose movement across the dialysis tube. The T. polium powder was dissolved in ethanol and distilled water. Then glucose was added to make a final concentration of 0.2 – ...

Objective(s): In food industry, the inhibition of tyrosinase is very important, because this enzyme catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones, which contribute in undesirable color and taste of fruits and vegetables. Teucrium polium L. var. gnaphalodes (Lamiaceae), a wild-growing flowering plant that has many applications in food preparations and...
