Survey and phytochemical analysis of seagrasses in the Gulf of Mannar, southeast coast of India

Abstract
Of the six genera of seagrasses recorded in India, four were present throughout a 1-year study period at a station off Hare Island, Tuticorin (8°45′ N, 78°12′ E), in the Gulf of Mannar region. Phytochemical analysis of these seagrass extracts revealed the presence of pharmaceutically potent secondary metabolites and appreciable quantities of primary and some secondary metabolites.
