Phytochemical profile and antimicrobial activity of turmeric grown in Andaman Islands

Abstract

Turmeric is one of the important spice that has many medicinal properties. The co-2 variety of turmeric grown in Andaman and Nicobar Islands were subjected to phytochemical assay. The results showed that the rhizomes of turmeric had highest phenolic (31.62 mg/g GAE) and flavonoid content (18.02 mg/g GAE) in methanolic extract than aqueous extract. The antioxidant assay was done by DPPH activity of two extracts and were increased with increasing concentration (10-75 µg/ml), the DPPH activity was showed highest in methanolic extract (26.02 mg BHA/g). The antimicrobial scavenging activity was found to be 49.79% and 17. 24% in methanolic and aqueous extract respectively. The methanol and aqueous extracts of the C. longa showed no antimicrobial activity against R. solanacearum, C. gloeosporioides and Fusarium spp., at all dilutions
