ABSTRACT
Traditional medicine systems consist of large numbers of plants with medicinal and pharmacological importance and hence represent an invaluable reservoir of new bioactive molecules. Alpinia galanga (family Zingiberaceae) is commonly known as galangal and has been used for its emmenagogue, aphrodisiac, abortifacient, carminative, antipyretic and anti-inflammatory qualities and used in the treatment of various diseases such as bronchitis, heart diseases, chronic enteritis, renal calculus, diabetes, rheumatism and kidney disorders. It was reported to contain, among other components, essential oils, tannins, phenol, glycosides, monoterpenes and carbohydrates. In the last few years, new compounds such as gallic acid glycoside, galangoisoflavonoid, β-sitosterol, galangin, alpinin, zerumbone and kampferide have been isolated from various parts of A. galanga. Therefore, the present review is aimed to summarize the information regarding A. galanga concerning the new phytoconstituents and pharmacological uses that have appeared in recent years.
