Consuming fruits and vegetables, with high phenolic compounds, reduces the incidence of heart and cerebrovascular diseases, reducingcancer mortality according to epidemiological studies. Morus is a genus whose fruits contain phenolic compounds such as anthocyaninsand flavonoids, with chemopreventive action. The objective was to compare phenolic components and the antiradical capacity in extracts ofthese fruits. Morus nigra and Morus alba were collected in Tucumán. We worked with dry lyophilized extracts, obtained by maceration, inhydroalcoholic mixtures, ethyl acetate, and dichloromethane. Phenols (mg/100g), flavonoids (mg/100g), anthocyanins (mg/100g), andantirradicalary capacity were quantified: PPHD* (%) and ABTS*+ (%). Morus nigra. Hydroalcoholic extract: Phenols: 1058.23.Flavonoids: 1116.00. Anthocyanins: 340.96. DPPH*: 49.16. ABTS*+: 34.21. Ethyl acetate extract: Phenols: 1012.23. Flavonoids: 1105.74.Anthocyanins: 324.28. DPPH*: 46.38. ABTS*+: 35.42. Dichloromethane extract: Phenols: 668.04. Flavonoids: 157.77. Anthocyanins: 3.34.DPPH*: 19.15. ABTS*+: 16.30. Morus alba: Hydroalcoholic extract: Phenols: 1048.58. Flavonoids: 773.85. Anthocyanins: 76.86. DPPH*:12.35. ABTS*+: 9.64. Ethyl acetate extract: Phenols: 1003.13. Flavonoids: 750.71. Anthocyanins: 63.51. DPPH*: 10.61. ABTS*+: 9.03.Dichloromethane extract: Phenols: 622.13, Flavonoids: 253.56. Anthocyanins: 0.05, DPPH*: 2.26. ABTS*+: 318. The hydroalcoholicextracts have more antioxidants. The free radical scavenging capacity is moderate in hydroalcoholic and ethyl acetate extracts, correlatingwith antioxidant capacity.
