ABSTRACT
Introduction: lipids from Cucurbita pepo L. seeds, rich in polyunsaturated fatty acids, show an effective antiinflammatory effect in the treatment of benign prostatic hyperplasia (BPH). The use of microwave energy in the extraction of natural compounds has among its main advantages quick heating, which saves time and energy in the process, thus reducing the general costs.Objectives: to study different extraction times to obtain lipids from Cucurbita pepo L. seeds through microwave-assisted extraction.
Methods: lipids from Cucurbita pepo L. seeds were extracted with ethanol as solvent at several times (1, 5, 10 y 15 min).The evaluation was based on attenuated total internal reflection spectrometry and gas chromatography to detect the major fatty acids responsible for the pharmacological action.
Results: the one-minute extraction time was the most efficient. Qualitative and quantitative analysis by attenuated total internal reflection spectrometry and gas chromatography indicated the presence of the major fatty acids reported in the literature as having pharmacological effect over benign prostate hyperplasia.
Conclusions: the results demonstrated the feasibility of employing microwave energy in the extraction of the lipid component from Cucurbita pepo L. seeds.
