It has been reported that rhizome of this plant have antibacterial, antifungal, anti-inflammatory, antioxidant and antitumor property. Methanol extract of Rhizome of Curcuma longa was investigated here to see the antimicrobial actions and anti-inflammatory effect. During the extraction process a purified single compound (D1) was isolated and investigated for its antimicrobial activity. Significant antimicrobial activity than penicillin were found for 500μg C. longa extract. Anti-inflammatory action of C. longa was also assessed using mice models. The purified compound D1 fraction showed antimicrobial action in 50μg concentration.
