Optimization of lipid extraction from aquatic plant Salvinia molesta D. S. Mitchell (Salviniaceae) with alternative solvents
Abstract
Salvinia molesta D. S. Mitchell (Salviniaceae) is an invasive aquatic plant that causes environmental and economic damage, but its rapid growth in eutrophic media can be used for the biotechnological use of its biomass. Thus, the aim of this work was to determine the best technique for lipid extraction from S. molesta, testing the solvents hexane:methanol (2:1 v/v), ethanol:water (10% v/v) and ethanol:water (4 % v/v), in association with auxiliary techniques: ultrasound with and without glass beads and the use of magnetic preparation at 17 and 34 ºC. The best yields obtained were the ones that used hexane:methanol 2:1 with the aid of ultrasound (8.30 ± 0.05%). The mixture of ethanol:water 10% with magnetic agitation at 34 ºC was also potential, as it uses less toxic solvents and presents a yield of 6.90 ± 0.21%.
