Medicinal properties of marine plants

Abstract Marine organism, animals, sponge, bacteria, actinobacteria, cyanobacteria, fungi, microalgae, seaweeds and mangroves are extremely important oceanic resources, that is, source of biologically active natural products. Marine natural products can be defined as biologically active products as secondary metabolites as well as enzymes, lipids, and heteropolysaccharides. Therefore, in this chapter, we deal with the bioactive application of some natural product, that is, isolated from marine natural resources such as Dysidea etheria , Laurencia obtuse , Aplidiopsis confluata , Tunicate didemnum sp., Nostoc linckia , and Lyngbya majuscule . Further, we also deal with the extraction and synthesis of these natural products
