Phytochemical Profile

The present study was intended to discover the preliminary phytochemicals of Dictyota dichotoma (Huds.) Lamouroux from Koothankuzhi coast, Tirunelveli district, the south east coast of Tamil Nadu, India. The preliminary phytochemical analysis was conducted in seven extracts namely methanol, acetone, chloroform, ethyl acetate, petroleum ether, hexane and benzene by Harborne method. The preliminary phytochemical analysis showed the presence of alkaloids, anthocyanin, anthraquinones, cardiac glycosides, catechin, coumarins, diterpenes, emodins, flavonoids, glycosides, leucoanthocyanin, lignins, phenols, phlobatannins, quinones, saponins, steroids, tannins, terpenoids and triterpenoids. Among the various phytochemicals studied, tannin showed the maximum presence, being found in seven different extracts and anthraquinones was observed in only one extract. From the results, it was noted that the extracts of Dictyota dichotoma (Huds.) Lamouroux was found to be the presence of a number of active secondary metabolites. This report will lead to the isolation and characterization of these active secondary metabolites for bioefficacy and bioactivity. Keywords: Phytochemical, Bioactive compounds, Seaweed extracts, Dictyota, Tamil Nadu.

Culture Extract

A novel hyaluronidase inhibitor (HI) was isolated from the culture extract of a marine- derived actinomycete strain. This strain MB-PO13 was isolated from ascidian (Molgula manhattensis) in Tokyo Bay. Out of about 1,000 isolates from various marine organisms, strain MB-PO13 had the strongest inhibitory activity and was selected for further study. The strain showed abundant-to-moderate growth on most media, forming a grayish mycelium. On the basis of the taxonomical characteristics, the strain was classified as belonging to the genus of Streptomyces and was named as Streptomyces sp. strain MB-PO13. The structure of HI was elucidated by interpretation of NMR data. HI displayed about 25-fold potent hyaluronidase inhibitory activity against hyaluronidase than glycyrrhizin. Keywords: marine actinomycetes; Streptomyces; hyaluronidase inhibitor
