New Antiproliferative Polyunsaturated Epoxy-Heneicosane Derivatives Isolated from the Brown Alga Lobophora variegata

HPTLC finger printing profile of brown alga Lobophora variegata

To establish the fingerprint profile of Lobophora variegata using high performance thin layer chromatography (HPTLC) technique. HPTLC studies were carried out using CAMAG HPTLC system equipped with Linomat V applicator; TLC scanner 3, Reprostar 3 and WIN CATS-4 software were used. HPTLC finger printing of methanolic extract of Lobophora variegata revealed 9 peaks with Rf values in the range of ...

The Tropical Brown Alga Lobophora variegata: A Source of Antiprotozoal Compounds

Lobophora variegata, a brown alga collected from the coast of the Yucatan peninsula, Mexico, was studied for antiprotozoal activity against Giardia intestinalis, Entamoeba histolytica and Trichomonas vaginalis. The whole extract showed the highest activity against T. vaginalis, with an IC(50) value of 3.2 microg/mL. For the fractions, the best antiprotozoal activity was found in non-polar fract...

The tropical brown alga Lobophora variegata as a bioindicator of mining

19 20 Previous field and laboratory studies have identified the alga Lobophora variegata as a good 21 candidate for biomonitoring metal contamination in the New Caledonia lagoon which is 22 subjected to intensive and extensive metal inputs from land-based mining activities. The aim 23 of this work was to further assess the bioindicative potential of this species by investigating, 24 in the fiel...

Growth, mortality and recruitment rates of the brown alga Lobophora variegata in relation to herbivory and nutrients on Bonaire

The tropical brown alga Lobophora variegata (Lamouroux) Womersley: a prospective bioindicator for Ag contamination in tropical coastal waters.

Uptake and depuration kinetics of dissolved silver were determined in the brown alga Lobophora variegata, using radiotracer techniques. Results indicate that this widely distributed alga could be a useful bioindicator species for surveying silver contamination in tropical environments. Indeed, results showed that the alga readily concentrates silver (algal concentration of silver was 7,000 time...
