Abstract
The nature derived therapeutics is getting intense attention rather than chemical synthesis and synthetic ones. Today the expansion of natural bioactive molecule market is started to be dominated and generic drug and therapeutic understanding looks like to leave its place to a new horizon. Thus, natural originated therapeutics under controlled production conditions are of importance. Besides the public attention on natural molecules are also gain advance and the demand on this bioactive molecules is also increasing dramatically. The bioactive molecules from microalgae show antioxidant, antibacterial, antiviral, anticancer, skin regenerative, sunscreen, antihypertensive, neuroprotective and immunostimulatory effects which are favorable for pharmaceutical, nutraceutical and cosmetics industry. Also a new concept known as functional nutrition also broaden the acceptability and utilization of microalgae derived bioactive metabolites in new dietary formulations. The expansion of microalgal biotechnology and the number of research gained from the role of biologically active microalgal metabolites display the emergence of the microalgae farming for new pharmaceutical formulations. In this study, we prepared solvent and water extracts of G. sulphuraria, N. texensis, S. bacillaris, E. carotinosa, C. minutissima, S. limacinum, C. cohnii, and C. vulgaris. Antioxidant activity using DPPH radical scavenging activity and total phenolic compounds were measured from the methanolic extracts and water extracts. With the bioactive extracts cytotoxicity test were performed on Hep-G2 and B16-F10 cell lines. The results display potential onset of novel therapeutic compounds derived from microalgae.
