Three species of red marine macro algae (Rhodophyta) from the Indian Ocean were analysed for the occurrence of conjugated polyenes. The composition of different lipid classes in these seaweeds along with their fatty acid composition has also been reported. Analysis of lipid classes of these seaweeds revealed that both Acanthophora spicifera (Ceramiales, Rhodophyta) and two species of Gracilaria...

The polysaccharides of Acanthophora spicifera and Cystoseira trinode were isolated and their components identified using different chemical and spectral techniques. Their effects were evaluated for the first time on hyperlipidemic rats. Atorvastatin Ca (Lipitor) was used as a reference drug. Results revealed that the polysaccharides isolated were of sulfate type. Acanthophora spicifera lowered ...

Acanthophora spicifera, red algae are known to possess antioxidant activities. The objective of this study is to evaluate the ameliorative effect of the ethyl acetate extract of A. spicifera against the puffer fish Arothron hispidus induced biochemical alterations and oxidative stress. 24 Mice were divided into four groups were used in this study. Group 1 received normal saline as control, Grou...

This work reported on the in vitro antibacterial activity of six selected marine algae (seaweeds) which have been selected and their extracts have been tested as an alternative to commonly used antibiotics. Extracts of six seaweed samples namely Codium decorticatum, Caulerpa scalpelliformis, Gracilaria crassa, Acanthophora spicifera, Sargassum wightii and Turbinaria conoides were collected from...

La Acanthophora spicifera un alga roja de fácil adaptación a diferentes condiciones ambientales, por su capacidad regenerarse fragmentación, convirtiéndola en una especie invasora áreas tropicales y subtropicales. Además, es conocida sus componentes bioactivos (antioxidantes, fitohormonas, fitopigmentos). En este estudio se plantea determinar las óptimas extracción compuestos antioxidantes la m...

Herbivory is a fundamental process determining reef resilience, and while algal farming damselfishes can help shape benthic assemblages, an understanding of their contribution to areas outside of defended territories is relatively unexplored. Here, we demonstrate how the farming damselfish Stegastes marginatus plays a dual role in benthic structuring by 1) contributing to persistence of the inv...

We investigate the survivorship, growth and diet preferences of hatchery-raised juvenile urchins, Tripneustes gratilla, to evaluate the efficacy of their use as biocontrol agents in the efforts to reduce alien invasive algae. In flow-through tanks, we measured urchin growth rates, feeding rates and feeding preferences among diets of the most common invasive algae found in Kāne'ohe Bay, Hawai'i:...

Various extracts of local marine red algae, Acanthophora spicifera were evaluated for antioxidant activity, total phenolic content and in-vitro toxicity. The antioxidant activity was measured using DPPH (1, 1-diphenyl-2-picrylhidrazyl) method, while Folin-Ciocalteu method was used for the total phenolic content. The cytotoxicity of the extracts were evaluated using invitro brine shrimp lethalit...
