RESUMO

The phytosterols, present in the non saponifiable portion of dietary fats have been pointed out as protective against cardiovascular diseases. The oleic acid is another compound with positive effects on the treatment and prevention of chronic diseases. Therefore, this study has evaluated four varieties of avocado (Persea americana Mill) for the composition of fatty acids and phytosterols. Among analyzed varieties (Wagner, Fuerte, Fortuna and Hass) analysed, Fuerte (20.093.16g/ 100g) and Wagner (20.991.43g/ 100g) presented the highest lipid content (p <0.05). Fuerte showed the highest content of oleic acid (63.16 0.11%). The amount of phytosterols was significantly different among the four analyzed varieties, being - sitosterol the most abundant out of the four sterols identified in the study, and Fuerte the richest variety in this compound (207.2117.63mg/100g) (p <0.05). Traces of cholesterol were found in the Fortuna and Fuerte varieties. The content of lipids and phytosterols increased with the ripening of the fruit; however, the amount of the fatty acid remained unchanged. The content of total lipids, oleic acids and -sitosterol were higher at the end of the harvest period. The results of this study indicate that the Fuerte variety may be the most appropriated fruit for consumption, aiming at the proven benefits of fatty acid and the phytosterols to health.
