The objective of this research was to determine the pharmacognostic study and quantify the content of total phenols of the leaves of Aloysia citrodora "cedrón" from the province of Otuzco La Libertad One copy of the plant species was duly identified in the Herbarium Truxillense (HUT) with code N°59746. The pharmacognostic study included the determination of macromorphological characteristics, its weight being: 0.07 g and dimensions: width (1 cm ± 0.1683), and length: (4.5 cm ± 0.7123 ), the physicochemical parameters of quality control: foreign matter (1%), residual humidity (9.99%), total ash (7.48% ± 0.7203), water soluble ashes (1.57% ± 0 , 1598) and ash insoluble in acid (1.29% ± 0.9539), water soluble substances: (11.98% ± 0.1959), ethanol of 50 ° GL: (15.56% ± 0.2718 ), 70 ° GL ethanol (14.69% ± 0.2659) and 96 ° GL ethanol: (7.81% ± 0.1969), which are within the range...

The present study aimed to quantify the total polyphenol content of Passiflora tripartitea var. mollisima "pur pur" from the district of Lucma, province of Gran Chimú, La Libertad region. A specimen of the plant species was duly identified in the Herbarium Truxillense (HUT). From the juice of the fruits, the ethanolic extract 50 °GL was prepared by refluxing. Total polyphenols were quantified by the Folin-Cicalteau method using UV-visible spectrophotometry. The results reported were 1.349 g tannic acid / 100 g Fresh fruit
