An investigation of the natural products chemistry of the red alga Laurencia marianensis Yamada, a species whose chemistry has not previously been described in the literature, yielded the new metabolite 1-[(3′S*,3a′lR*,4′R*,7′S*,7a′S*)-7′-bromo-7a′-methyl-3′-(1′-methylethyl)octahydro-1′H-inden-4′-yl] ethanone (1) and the known metabolites deoxyprepacifenol (2) and pacifenol (3). The full n.m.r. characterization of (2) and (3) is reported for the first time.

Haemagglutination Activity

Lectin is a protein which has the ability to bind carbohydrates and named as haemagglutinin. Lectins with specific carbohydrate specificity have been purified from various plant tissues and other organisms and exploited extensively in many aspects of biochemistry and biomedicine. Similar to land plants, lectins from marine algae appear to be useful in some biological applications. Although several studies on lectins from marine algae have been reported till date, few lectins from algae have been characterized in detail. The present study was focused on the lectin isolated from C.sinuosa. The algal lectin has high sugar specificity with N-acetylglucosamine and higher enzyme activity with trypsin. This lectin was identified as CaCl2 dependent – ‘C’ type lectin and was sensitive to EDTA. Higher H.A titre value was observed with CaCl2 and the lower with MnCl2 and ZnCl2 . Significant lectin activity was observed between pH 7 to 8 and temperature between 20 to 40 O C

In the world, seaweeds or marine macro algae area unit is renewable living resources that are used as a several components like food, feed, and fertilizers. They are typically live hooked up to rock or alternative laborious substrata in coastal areas. Turbinaria found in tropical marine waters, which grows on rocky substrates. Turbinaria belongs to the class- Anthozoa, Order-Scleractinia, family-Dendrophylliidae, Genus- Turbinaria. The aim of the present study is the phytochemical analyses were evaluated for the marine algae Turbinaria conoides and Turbinaria ornate from Mandapam coast, Rameswaram, Tamil Nadu, India. To cope with the assessment of the chemical composition of assorted marine seaweeds were extracted from different solvents. The current study reveals that the seaweeds contain a high quantity of phytochemical constituents. Besides, the presence of alkaloids, terpenoids, steroids, tannins, saponins, flavonoids, phenols, coumarins, proteins, carbohydrates, quinones and glycosides from Turbinaria ornata and Turbinaria conoides. This report will lead to the isolation and characterization of these active secondary metabolites for bio-efficacy and bioactivity. Therefore, seaweed extracts possessed higher amount of phytochemicals and which proves that these selected seaweeds will have provide unique and novel metabolites of unprecedented structures, with antibacterial, antifungal, antiviral, anti-plasmodial, nematicidal, anti-inflammatory, anticancer, and anti-angiogenic activities, these bioactive compounds may provide high-quality drug candidates for pharmaceutical applications, as well as agricultural and industrial applications. KEYWORDS: Turbinaria, Coumarins, Seaweeds, Phytochemicals and Turbinaria conodies
