ABSTRACT

OBJECTIVE: To evaluate the similarities among fatty acid compositions of vegetable oils sold in the Brazilian market and those present in a reference health product used to treat wounds.

 

METHODS: The relative amounts of fatty acids in 21 types of vegetable oils, purchased in the Brazilian market, were assessed using gas chromatography-mass spectrometry and flame ionization detection.

 

MAIN RESULTS: The studied oils had similar fatty acid compositions to the reference product (caprylic acid, 18.8%; capric acid, 17.4%; oleic acid, 27.5%; and linoleic acid, 28.1%). The presence of caprylic acid (10.45% +/- 0.07%), capric acid (5.8% +/- 0.75%), lauric acid (45.63% +/- 0.93%), and myristic acid (16.33% +/- 2.23%) were detected in all the vegetable oils tested. Oleic acid (52.94% +/- 12.54%) was present in andiroba, avocado, canola, copaiba, olive, palm, pequi, and pracaxi oils and featured prominently in olive oil (75.8%). Linoleic acid (57.09% +/- 8.47%) was present in corn, cottonseed, grapeseed, passion fruit, and sunflower oils and in mixed oils (olive with soybean and sunflower with corn and canola).

 

CONCLUSIONS: Most of the vegetable oils tested are products of plants from tropical climates, where they are abundant and easy to cultivate. It is possible that a balanced composition of fatty acids obtained from natural sources could be an effective alternative treatment for wounds.
