Introduction Pterostilbene is a chemical classified as a benzylidene compound (more specifically a stilbene) and is biologically classified as a phytoalexin, which are antimicrobial substances that are part of the plant’s defense system and are synthesized in response to pathogen infection. This monograph focuses on trans-pterostilbene. Stilbenes are low molecular weight (approximately 200-300 ...

BACKGROUND The study of traditional knowledge of medicinal plants has led to discoveries that have helped combat diseases and improve healthcare. However, the development of quantitative measures that can assist our quest for new medicinal plants has not greatly advanced in recent years. Phylogenetic tools have entered many scientific fields in the last two decades to provide explanatory power,...

BACKGROUND Traditional Indian and Australian medicinal plant extracts were investigated to determine their therapeutic potential to inhibit key enzymes in carbohydrate metabolism, which has relevance to the management of hyperglycemia and type 2 diabetes. The antioxidant activities were also assessed. METHODS The evaluation of enzyme inhibitory activity of seven Australian aboriginal medicina...

Polyphenols from four medicinal plants of Burkina Faso, Combretum micranthum, Khaya senegalensis, Pterocarpus erinaceus and Sida acuta, were screened for their antioxidant and antimicrobial activities against pathogenic bacteria. The medicinal plants displayed different polyphenols contents and antioxidant activities. The bark of P. erinaceus had the highest antioxidant activity. Some microorga...

Objective: To evaluate the hepatoprotective activity of Pterocarpus marsupium stem bark extracts against carbon tetrachloride (CCl 4 )-induced hepatotoxicity. Materials and methods: Hepatotoxicity was induced in male Wistar rats by intraperitoneal injection of CCl 4 (0.1 ml/kg/day for 10 days). Methanol and aqueous extracts of P. marsupium stem bark were administered to the experimental rats (2...

The potential of 6 tree species (Leucaena leucocephala, Acacia mangium, Peltophorum pterocarpum, Pterocarpus macrocarpus, Lagerstroemia floribunda, Eucalyptus camaldulensis) for phytoremediation of Pb in sand tailings (total Pb >9850 mg kg(-1)) from KEMCO Pb mine in Kanchanaburi province, Thailand, were investigated employing a pot experiment (3 months) and field trial experiment (12 months). I...

The coloring behavior of santalin, a natural reddish-brown dye derived from sandalwood, has been investigated in this work for the dyeing silk fabrics while being heated MW radiation. Microwave (MW) radiation up to 5 min employed isolate colorant (Santalin) red sandalwood (Ptrecarpus santalinus) selected medium, and bio-mordants competing with salts as chemical-mordants have included. Statistic...
