Flavonoid: A Mini Review on Galangin

Abstract

Studies on flavonoids from plant sources has gained a momentum due to their versatile health benefits. The main sources of flavonoids in humans are fruits, vegetables, red wine and tea. They are small molecular weight secondary metabolites produced in different parts of the plant such as seeds, bark, root, fruits and flowers. Galangin (3,5,7-trihydroxyflavone) a naturally occurring flavonoid is present in roots of Alpinia officinarum, honey and propolis. Its extraction and detection has been reported using various methods such as chromatography, spectrophotometric and electrochemical methods associated with other sophisticated techniques. Galangin showed various pharmacological activities such as anti-inflammatory, antioxidative, radical scavenging, anticancer activity and hypolipidimic activity. The present review discusses the pharmacological activities, pharmacokinetics and bioanalytical aspects of galangin, which can be beneficial for researchers working in the field of galangin

Influence of Thermal Treatment on the Composition of Alpinia officinarum Rhizome

“…About 90 biologically active ingredients have been isolated and identified from it, containing mainly phenolic compounds, especially diarylheptanoids, which are one of the most efficient active substances [14]. Another important compound found in Alpinia rhizome is galangin (3,5,7-trihydroxyflavone), one of the polyphenolic active compounds present in Alpinia officinarum and honey, belonging to flavonoids [17,18]. Flavonoids have a multidirectional therapeutic effect, which has been proven in many in vivo and in vitro studies.…”
