In the present work, four species of microalgae: Spirulina platensis (SP), Chlorella vulgaris (CV), Haematococcus pluvialis (HP), and the diatom Phaeodactylum tricornutum (PT) were selected as raw materials for the recovery of multifunctional extracts. Ultrasonic assisted extraction (UAE) using different solvents was applied under specific optimized conditions. Organic solvents such as hexane, ...

The cuticular lipid compounds, usually named waxes, present in the layering of Quercus suber adult leaves were extracted with solvents different polarities (n-hexane, dichloromethane and acetone) analysed by GC–MS. Q. have a substantial wax layer (2.8% leaf mass 239 μg/cm2), composed predominantly terpenes (43–63% all compounds), followed aliphatic long chain molecules, mainly fatty acids, smal...

As fossil fuels are the principal source for automobile and energy sectors, global warming a rapid decrease in their availability seen. Alternative that sustainable, renewable, eco-friendly widely investigated order to maintain an aesthetic environment combat fuel depletion. Biofuels have ability both reduce pollution provide energy. This study focuses on extraction of oil from freshwater micro...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were com...

The leaves of Eucalyptus have multiple biological activities such as antimicrobial, antiseptic, antioxidant, and antifungal. A Soxhlet extraction, SLE, HD were used to obtain extracts from the six species, E. globulus, oblicua, pavaflora, camaldulensis, viminalis, nitens, study their antioxidant capacity. Solvents acetone, dichloromethane, ethanol, hexane, methanol, water how polarity influence...

The extraction and transesterification of soil lipids into fatty acid methyl esters (FAMEs) is a useful technique for studying soil microbial communities. The objective of this study was to find the best solvent mixture to extract soil lipids with a pressurized solvent extractor system. Four solvent mixtures were selected for testing: chloroform:methanol:phosphate buffer (1:2:0.8, v/v/v), chlor...
