Useful Strategies for Algal Volatile Analysis

Sesquiterpenes from the essential oil of Laurencia dendroidea (Ceramiales, Rhodophyta): isolation, biological activities and distribution among seaweeds

“…The very small amount found in GB and GD2 might be explained by the sampling method used. HS-SPME integrates extraction and concentration of volatile compounds into a single step, leading to a high sensitivity (Gressler et al, 2009), not achieved with other extraction methods (like hydrodistillation and solvent extract). In Palisada perforata (Bory) K.W.…”

“…Since these compounds can cross the membrane and be released in the atmosphere, they play an important role as chemical communications for algae in marine ecosystems (Fink, 2007;Gressler et al, 2009;Gressler et al, 2011).…”

“…A wide range of volatile secondary metabolites such as halogenated and sulfur compounds (Kladi et al, 2004;Karabay-Yavasoglu et al, 2007), hydrocarbons, alcohols, phenols, aldehydes, ketones, acids, esters, terpenes and other compounds (Gressler et al, 2009), are distributed among the seaweeds. However, few works reported the essential oil composition of seaweeds.…”

Seasonal changes in the pigment composition of natural population of Gracilaria domingensis (Gracilariales, Rhodophyta)

“…Marine macroalgae are important source of bioactive compounds to the pharmaceutical, cosmetic and food industries (Cardozo et al, 2007;Carignan et al, 2009;Gressler et al, 2009;Gressler et al, 2010). In the marine environment, seaweeds exhibit a distinct and welldefi ned vertical distribution pattern.…”

Comparison of extraction and transesterification methods on the determination of the fatty acid contents of three Brazilian seaweed species

“…In addition, they provide food and shelter for many animals. These organisms constitute a source of compounds with several different applications that can be used in the food, pharmaceutical and biotechnology industries (Gressler et a., 2009;Cardozo et al, 2007;.…”
