Abstract

Portulaca oleracea L., commonly known as purslane, is a plant consumed in Europe, Asia and Africa, with nutraceutical compounds and essential fatty acids whose content exceeds that of vegetables such as spinach and lettuce. On the other hand, organic fertilization improves the physical-chemical characteristics of the soil and thus promotes growth, physiology and secondary metabolism, improving the chemical composition of the plant.  In order to evaluate the effect of organic fertilization on fatty acid content and anti-diabetic activity (α-Glucosidase), greenhouse-grown plants were subjected to three treatments: control without additional fertilizers, with compost and vermicompost. The results indicated that vermicompost significantly increased oleic and linoleic acid content. However, palmitic acid content decreased, although other saturated fatty acids such as lauric, myristic and stearic acids did not show variations in the different treatments. Of the polyunsaturated essential fatty acids, linolenic acid (omega-3) increased in the control treatment. On the other hand, the enzyme α-Glucosidase did not show differences in the different fertilization treatments. However, its high percentage of inhibition (60 %) positions it as a species with high antidiabetic potential.
