Introduction: Morus alba, commonly known as mulberry, is a tree belonging to the genus Morus, family Moraceae. It is used as an ornamental plant; its leaves are rich in minerals, vitamins, folic acid, amino acids, and it is the only food of the silkworm. It has several medicinal properties, which have been used in the treatment of acne, as an antipyretic, diuretic and reducing cholesterol and blood pressure. Recent studies have developed the antiproliferative capacity against cancer. Phytochemical characterization of plants is important because through these studies may suggest the presence of actives principles with biological activity such as flavonoids, polyphenols, among others. Objective: Phytochemical screening and determining the content of polyphenols and flavonoids in hydroalcoholic extracts of mulberry leaves. Material and Methods: The plant material was dried under controlled temperature and humidity. The screening was performed by classical fractionation methodology solvent polarity. Alcoholic extraction was performed at different concentrations (96, 70, 50 and 30%), at room temperature for three days and the polyphenol and flavonoid content was determined by standard techniques as described using pyrogallol and quercetin, respectively. Results: Oil/fat, alkaloids, triterpenes/steroids, catechins, reducing sugars, flavonoids and phenol/tannins were detecting. The highest polyphenol content was found in 95% ethanol extract (293.29 mg/g) and the lowest in extract 30% (52.74 mg/g). The flavonoids behaver was similarly to polyphenols, being the 95% ethanol extract the higher value (455.46 mg/g) and 30% the lower value (62.61 mg/g). Conclusions: Six groups of metabolites were observed. The highest polyphenols and flavonoids content were found in 95% ethanol extract.
