EXTRACTION OF OIL FROM Luffa cylindrica L. SEEDS AND APPLICATION IN SKIN CREAM

Abstract

In this study, oil was extracted from the seeds of Luffa cylindrica L. using maceration with n-hexane at various material-to-solvent ratios. The 1:5 ratio resulted in the highest oil content, yielding 53.48%. The extracted oil had a density of 0.86 g/cm³, an acid value of 41.978 mg/g, and a saponification value of 232 mg KOH/g. Gas chromatography-mass spectrometry (GC-MS) analysis revealed significant levels of oleic acid (27.66%) and palmitic acid (12.3%). The oil demonstrated antibacterial activity against Staphylococcus aureus, with a 7 mm inhibition zone. It was incorporated into a skin cream formulation at a concentration of 5%. The final product exhibited a non-greasy texture, good spreadability, rapid absorption, nonirritating to the skin, and microbiological safety, receiving positive feedback from consumers. These findings suggest that Luffa seed oil is a promising bio-based emollient for skincare applications.
