DIAZ-SOLARES, Maykelis et al. Antioxidant and healing potential of fresh Morus alba extracts. Pastos y Forrajes [online]. 2017, vol.40, n.2, pp. 135-143. ISSN 2078-8452.

Mulberry is considered a valuable forage plant, mostly because of its bioactive phytochemical components that exert positive effects on human and animal health. Based on this, a study was conducted with the following objectives: to determine quantitatively the concentration of flavonoids, to compare the specific activities of the antioxidant enzymes catalase and peroxidase and to evaluate the in vivo healing effect of the fresh leaf, bark and root extracts, in the variety tigreada of Morus alba. The simple classification ANOVA and Duncan's multiple range test were carried out for mean comparison (p< 0,05). The leaf extract showed the highest concentration of flavonoids, catalase and peroxidase, and significantly differed from the bark and the root which did not differ from each other. In order to evaluate the healing capacity, Wistar rats were used as animal model. Eighteen days after the incision was made, the leaf and root extracts did not differ from the control, because the percentages of closed wounds were 99,92 and 99,94 %, respectively; while the bark extract was significantly lower, but higher than the negative control, and showed 90,50 % of closing. The antioxidant and healing potential of fresh mulberry leaf and root extracts was proven, increasing its value as multipurpose plant.
