Bioactive Compounds and Properties of Seaweeds—A Review

Abstract

In last three decades the discovery of metabolite and biological activities from macroalgae has been increased significantly. Many sophisticated modern research tools are available for making of chemical compound but there are still many natural bioactive compounds in the womb of nature which is a mystery, scientist are still working to find out more biologically active compounds. Bioactive substances from seaweeds currently receive the more attention from the pharmaceutical companies for the drug development as well as the researchers. Seaweeds are taking majority of attention from scientists because of its phenomenon bioactive compounds and its properties like anti-viral, anti-tumor, anti-inflammatory and anti-lipedimic and may more properties. This current review described mainly substances like metabolite, properties, and types of seaweeds. Emphasis is given to main metabolite and properties of seaweeds.

“…Senyawa bioaktif ini memiliki aktivitas hipokolesterolemik, antiviral, antibiotik, anti-inflamatori, anti-trombin, antikoagulasi, antilipemik, inhibitor enzim, dan stimulan (Pal et al, 2014 Polisakarida rumput laut diantaranya alginat, fukoidan, mannitol, dan laminarin (Yuan, 2008;Casas, 2009). Senyawa-senyawa ini mempunyai pengaruh hiperkolesterolemik yang menyebabkan terbentuknya formasi sistem viskositas di dalam usus halus yang menyebabkan penurunan kecepatan penyerapan nutrisi seperti glukosa dan lemak di dalam darah, lalu membentuk suatu koloid berion, selanjutnya dikeluarkan bersama feses (Kiriyama et al, 1968;Lamela et al, 1989;Panlasigui et al, 2003).…”

“…These fibers play an active role against obesity, cholesterol and large intestine cancer. [17,19] In algae, high amount of dietary fibers (% dry weight) reported exceed those for wheat bran, ranging from 23.5 (Codium reediae) to 64.0 (Gracilaria spp). [16] Porphyra umbilicalis contains slightly more fiber (3.8 g/100 g) than bananas (3.1 g/100 g).…”

“…65% of dry weight. [17] Many water soluble polysaccharides such as pectins, guar gum, etc. possess hypoglycemic and hypocholesterolemic effects, whereas the water-insoluble polysaccharides like cellulose have laxative effect.…”

“…Seaweeds are the only source of phytochemicals namely agar, alginic acid, laminarin, fucoidin, galactans and carrageenan, which are extensively used in various industries such as food, confectionary, textiles, pharmaceuticals, dairy and paper industries mostly as gelling, stabilizing and thickening agents 6 . Industrial macro algal use includes the extraction of phycocolloids and biochemicals.…”
