“…The free-radical scavenging activity of plant extracts was analysed by using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) test (Awah et al, 2012;Souza et al, 2012). The scavenging activity of extracts on the DPPH free radicals were evaluated according to the method reported by Awah et al (Awah et al, 2012).…”

Extracts from five indigenous Palestinian medicinal plants including Rosmarinus officinalis, Pisidium guajava, Punica granatum peel, grape seeds and Teucrium polium were investigated for antimicrobial and free radical scavenging activities against eight microorganisms, using well diffusion method. The microorganisms included six bacterial isolates (i.e. Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginos, Klebsiella pneumonia, Bacillus subtilis and Micrococcus luteus) and two fungal isolates (i.e. Candida albicans and Aspergillus niger). A standard antioxidant assay was performed on the plant extracts to assess their capability in scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH). Of the five tested plant extract, only Rosmarinus offcinalis extract contained significant antimicrobial activity against all eight microbial isolates including Pseudomonas aeruginosa. Extracts from other four plants exhibited a variable antimicrobial activity against all microorganisms, except Pseudomonas aeruginosa. Significant antioxidant activity was detected in all plant extracts. However, extracts from Pisidium guajava leaves contained significantly higher antioxidant activity compared to the other extracts tested. The antimicrobial and scavenging activities detected in this in vitro study in extracts from the five Palestinian medicinal plants suggest that further study is needed to identify active compounds to target diseases caused by a wide-spectrum pathogens.

“…Algal polysaccharides have been demonstrated to play an important role as free-radical scavengers and antioxidants for the prevention of oxidative damage in living organisms (Kim et al, 2007;Wang et al, 2009;Souza et al, 2012). In the present study the macroalgae were supplied complete to organisms of L. vannamei and it is possibly that this components had an important effect in the growth and survival response.…”

ABSTRACT. The antioxidant activity of meals, growth performance, dry matter, crude protein and amino acid apparent digestibility coefficients (ADC) were determined for three macroalgae in Pacific white shrimp juveniles: Gracilaria vermiculophylla, Dictyota dichotoma and Ulva lactuca. For the digestibility determination, test diets included 15% of the test ingredients and 85% of a control diet supplemented with 1% chromic oxide. The amino acid content in the ingredients, diets and feces were analyzed using HPLC. In general, nutrient digestibility values were far higher in the diets with macroalgae meals than in the control diet. In conclusion, diets with the macroalgae U. lactuca and G. vermiculophylla in particular showed high antioxidant activity, high amino acid digestibility and improved Litopenaeus vannamei growth.

“…It is also supported by data that show polysaccharides from Gigartina skottsbergii, Tichocarpus crinitus, Gloiopeltis furcate, Chondrus crispus, and Halymenia durvillei, Geogiella confluens, and Cryptonemia seminervis are sulfated 15−42% (Barabanova et al 2005;Fenoradosoa et al 2009;Kolender and Matulewicz 2002;Mendes et al 2014;McCandless et al 1973;Piriz and Cerezo 1991;Yu et al 2010). In contrast, low sulfate content was detected in acidic polysaccharides from other red seaweed: 2.8% from P. decipiens (Matsuhiro and Urzua 1996), 8.4% from Grarcilaria birdiae (Souza et al 2012), 4.8% from Gracilaria cornea (Melo et al 2002), 1.2% from Gracilaria dura (Marinho-Soriano and Bourret 2005), and 5.08% from H. musciformis (Sousa et al 2016). The monosaccharide composition of SP1 and SP2 analyzed by Values were obtained by setting the sum of each mole number at 100% HPAEC-PAD revealed that galactose is the major monosaccharide (92.9% and 91.3% in mole %), while fucose (6.5% and 7.4%), glucose (1.8% and 0.6%), and xylose (0.9% and 0.7%) are present as minor components (Table 3 and Fig.…”

: This study aimed to isolate and characterize sulfated polysaccharides (SPs) from Iridaea cordata and evaluate their anticancer activity. SPs of the Antarctic red seaweed were obtained by CaCl 2 (SP1) and ethanol precipitations (SP2) following diluted acid extraction at room temperature. Yields of SP1 and SP2 were approximately 14% and 23%, respectively, of the dry weight of red seaweed. The average molecular mass of the SP1 and SP2 was estimated about 1.84 × 10 3 and 1.42 × 10 3 kDa, respectively, by size-fractionation High-Performance Liquid Chromatography (HPLC). From the High-Performance AnionExchange Chromatography-Pulsed Amperometric Detection (HPAEC-PAD) analysis, the main monosaccharide was galactose with glucose and fucose as minor components. The sulfate content of SP2 (40.4%) was slightly higher than that of SP1 (33.8%). The FT-IR spectra also showed characteristic band of carrageenan-like sulfated polysaccharides. Taken together the SPs are thought to be carrageenan-like sulfated galactan. The polysaccharides (SPs) from I. cordata exhibited weak antitumor activity against PC-3 (prostate cancer), HeLa (cervical cancer), and HT-29 (human colon adenocarcinoma). To our knowledge, this is the first data on biological activity of the Antarctic red seaweed I. cordata.
