Antimicrobial Activity of Callistemon Citrinus (Bottle Brush) and its Phytochemical Investivation

Abstract

Callistemon citrinus is a plant species that has been used for various medicinal purposes.In this Study,the phytochemical constituents of the methanol,ethanol,acetone and aqueous extract of Callistemon citrinus were anlysed. The results showed that all the extracts contained alkaloids,flavonoid,tannins,saponins,and phenols.however the highest concentration of these phytochemicals was found in the methanol extract followed by the ethanol,acetone,and aqueous extract. Alkaloids are nitrogen-containing compounds that have a wide range of biological activities such as analgesic, antitumor, and anti-inflammatory properties. Flavonoids are polyphenolic compounds that have antioxidant, anti-inflammatory, and anticancer properties. Trumins are polyphenolic compounds that have astringent and antioxidant properties. Saponins are glycosides that have antifungal, antibacterial, and anti-inflammatory properties. Phenols are organic compow1ds that have antioxidant and anti-inflammatory properties. The methanol extract showed the highest concentration of alkaloids, flavonoids, tannins, saponins, and phenols. This may be due to the fact that methanol is a polar solvent that can extract a wide range ofphytochemicals from plant materials. The ethanol extract also contained a high concentration of these phytochemicals, followed by the aceton~ and aqueous extracts. The fmdings of this study suggest that Cal/istemon citrinus could be*p.o~ · · I source of natural
