This review covers the marine natural products literature for the year 2000 and is organized phylogenetically, with sections on marine microorganisms and phytoplankton, green algae, brown algae, red algae, sponges, coelenterates, bryozoans, molluscs, tunicates. echinoderms and miscellaneous marine organisms. There is an emphasis on new structures, stressing their biological activities, source o...

In contrast to the generally boron-poor terrestrial environment, the concentration of boron in the marine environment is relatively high (0.4 mM) and while there has been extensive interest in its use as a surrogate of pH in paleoclimate studies in the context of climate change-related questions, the relatively depth independent, and the generally non-nutrient-like concentration profile of this...

The aim of this study was to identify seaweeds in the southern coasts of Iranian waters and providing an atlas. The collecting and identification of seaweeds in the southern coasts of Iranian waters were carried out from October 2001 to September 2003. Data on vegetation were gathered in sub tidal and intertidal zones by seasonal and monthly sampling, respectively. Samples were transferred to t...

A survey of the marine plants of the Walpole and Nornalup Inlets Marine Park has recorded 49 species of marine benthic algae and seagrasses, including 15 green algae, 11 brown algae, 18 red algae, 4 seagrasses, and one cyanobacterium, representing a substantial increase on the 14 previously recorded species. Most species are relatively common elements of the south-western Australian marine flor...

Estimation and comparison of effective compounds (mineral contents, amino acids compositions, fatty acids distributions, protein, fat and total fiber contents) in two algae species Sirophysalis trinodis and Polycladia myrica collected from Qeshm Island were done. The samples washed up with tap water and then were dried in an oven at 40 ◦C for 3 days. The dried algae samples were pulverized and ...

This paper presents the alkaloids found in green, brown and red marine algae. Algal chemistry has interested many researchers in order to develop new drugs, as algae include compounds with functional groups which are characteristic from this particular source. Among these compounds, alkaloids present special interest because of their pharmacological activities. Alkaloid chemistry has been widel...

A simple, fast and effective pre-concentration method for the determination of Cu (copper) and Ni (nickel) was developed using a Surfactant Assisted Dispersive Liquid-Liquid Microextraction (SA-DLLME) coupled by UV-Vis spectrophotometry in marine brown algae. The complexing agent was 1- (2- pyridylazo) – 2 - naphthol (PAN).The effects of various experimental parameters in the extraction ste...

the present study was aimed to assess the influence of brown marine algae and vitamin e (ve) (160 ppm α-tocopheryl acetate) on stability of chicken meat enriched with fish oil. in this study, 360 d-old broilers (arbor acres plus) were randomly assigned to 6 treatment groups with 4 replicates of 15 birds in each. experimental groups consisted of corn-soybean basal diet (c), corn-soybean basal di...
