Oral administration of terpenoids and phenol fraction of Padina gymnospora stimulates the nonspecific immune response and expression of immune genes, and protects the common carp (Cyprinus carpio) from experimental Aeromonas hydrophila infection.

Common carp (Cyprinus carpio), a valuable aquaculture species susceptible to various infections, requires effective immune enhancement strategies. This study investigates the immunomodulatory effects of orally administered terpenoids and phenol fraction (TPF) from Padina gymnospora in C. carpio, focusing on stimulation of nonspecific immune response, immune gene expression, and protection against experimental infection.

Marine halophyte derived polyphenols inhibit glioma cell growth through mitogen-activated protein kinase signaling pathway.

Plants that are pharmacologically significant require intensive phytochemical characterization for bioactive profiling of the compounds, which has enabled their safe use in ayurvedic medicine. The present study is focused on the phytochemical analyses, quantitative estimation and profiling of secondary metabolites of leaf extract, as well as the antioxidant and cytotoxic activity of the potent halophytes such as Avicennia marina, Ceriops tagal, Ipomoea pes-caprae, and Sonneratia apetala. The in vitro antioxidant property was investigated using DPPH, ferric reducing antioxidant capacity (FRAP) assay.

Polysaccharides from marine macroalga, Padina gymnospora improve the nonspecific and specific immune responses of Cyprinus carpio and protect it from different pathogens.

Immunostimulation by plant-derived compounds presents a fascinating alternative to vaccines and antibiotics in aquaculture. Fish farmers are longing for immunostimulants that activate both specific and nonspecific immune responses of fish and protect fishes from all possible infections. In this study, we observed that polysaccharide fraction from marine macroalga, Padina gymnospora stimulated the immune response of common carp Cyprinus carpio (Filed for patent, Indian patent no.
