“…(2009) who reported that concentrations of isoflavone obtained from Clover (Trifolium L.) using ASE increased with increasing temperature from 75 °C to 125 °C with no evidence of thermal degradation of the target compounds. Several other studies using ASE also reported the similar effect temof perature on extraction yield of phenolics from plant materials (Santoyo et al, 2009;Zaibunnisa et al, 2009). This is not surprising since increasing temperatures enhances the solubility of many compounds.…”

Optimisation of accelerated solvent extraction of antioxidant compounds from rosemary (Rosmarinus officinalis L.), marjoram (Origanum majorana L.) and oregano (Origanum vulgare L.) using response surface methodology. Food Chemistry, 126, (1),pp. 339-346. doi:10.1016Chemistry, 126, (1),pp. 339-346. doi:10. /j.foodchem.2010 Optimisation of accelerated solvent extraction of antioxidant compounds from rosemary (Rosmarinus officinalis L.), marjoram (Origanum majorana L.) and oregano (Origanum vulgare L.) using response surface methodology Food Chemistry 126, p339-346. The present study optimised the accelerated solvent extraction (ASE) conditions (Dionex ASEÒ 200, USA) to maximise the antioxidant capacity of the extracts from three spices of Lamiaceae family; rosemary, oregano and marjoram. Optimised conditions with regard to extraction temperature (66-129 °C) and solvent concentration (32-88% methanol) were identified using response surface methodology (RSM). For all three spices results showed that 129 °C was the optimum temperature in order to obtain extracts with high antioxidant activity. Optimal methanol concentrations with respect to the antioxidant activity of rosemary and marjoram extracts were 56% and 57% respectively. Oregano showed a different response to the effect of methanol concentration and was optimally extracted at 33%. The antioxidant activity yields of the optimal ASE extracts were significantly (p < 0.05) higher than solid/liquid extracts. The predicted models were highly significant (p < 0.05) for both total phenol (TP) and ferric reducing antioxidant property (FRAP) values in all the spices with high regression coefficients (R2) ranging from 0.952 to 0.999.

“…However, D. salina and H. pluvialis biomass has been poorly screened for the presence of other active compounds. Thus, several studies reported the presence of antimicrobial compounds , Santoyo et al, 2009) and extracellular polymeric substances (Mishra and Jha, 2009) in these microalgae, but no studies have evaluated their potential to produce antiviral agents.…”

Antiviral compounds obtained from microalgae commonly used as carotenoid sources

Pressurized liquid extraction (PLE), an environmentally friendly technique, has been used to obtain antiviral compounds from microalgae commonly used as carotenoids sources: Haematococcus pluvialis and Dunaliella salina. The antiviral properties of PLE extracts (hexane, ethanol and water) were evaluated against herpes simplex virus type 1 (HSV-1) at different stages during viral infection. Pre-treatment of Vero cells with 75 g mL -1 of H. pluvialis ethanol extract inhibited virus infection by approx. 85%, whereas the same concentration of water and hexane extracts reduced the virus infectivity 75% and 50% respectively. D. salina extracts were less effective than H. pluvialis extracts and presented a different behaviour, since water and ethanol extracts produced a similar virus inhibition (65%). Moreover, H. pluvialis ethanol extract was also the most effective against HSV-1 intracellular replication.The antiviral activity of water PLE extracts was found to correlate with polysaccharides, since the polysaccharide-rich fraction isolated from these extracts showed higher antiviral activity than the original water extracts. A GC-MS characterization of the H.pluvialis ethanol extract showed the antiviral activity of this extract could be partially related with the presence of short chain fatty acids, although other compounds could be involved in this activity; meanwhile, in the case of D. salina ethanol extract other compounds seemed to be implied, such as: β-ionone, neophytadiene, phytol, palmitic acid and α-linolenic acid.

ResumoPenicillium expansum destaca-se como itopatógeno cosmopolita e altamente agressivo, responsável pelo bolor azul, doença que proporciona a perda de qualidade e quantidade pós colheita de frutos. Aplicações de produtos químicos é tradicionalmente o método de controle mais utilizado. No entanto, a bioprospecção de algas tem-se revelado uma fonte para uma grande quantidade de compostos antifúngicos. Desta maneira, o presente trabalho tem por objetivo avaliar os efeitos dos extratos etanólicos de sete microalgas e cinco macroalgas contra P. expasum. O potencial antifúngico foi avaliado analisando-se a porcentagem de germinação, o tamanho do tubo germinativo, a concentração mínima inibitória e a concentração efetiva mediana (CE 50
