The present research work was carried out with the aim of contributing to the study of the pharmacognostic characteristics and the quantification of total anthocyanins of the fruit Prunus serotina subsp. capuli (Cav.) McVaugh (Rosaceae) "capuli". The fruits were collected at Campana Village, north of Cajabamba, Cajamarca Region, and were identified in the Herbarium Truxillense (HUT) of the National University of Trujillo with register No. 58336. The pharmacognostic characteristics were got according to the method of Miranda M. & Cuellar A., obtaining organoleptic characteristics such as sui generis odor, reddish black epicarp color, green mesocarp color, sweet- sour flavor and smooth texture; the macromorphological characteristics, weight 1.6937 ± 0.2910 g, length 0.904 ± 0.075 cm and width 1.067 ± 0.121 cm in dimensions, fresh condition, ovoid shape and smooth surface, comply with quality parameters; physicochemical characteristics such as relative humidity 21.7153 ± 0.3585 %, residual humidity 6.4527 ± 0.2323 %, total humidity 28.1680 %, total ashes 1.3914 ± 0.006 %, water soluble ashes 0.6977 ± 0.1443 %, ashes insoluble in hydrochloric acid 0.3927 ± 0.2337 %, substances soluble in ethanol of 96° G.L. 17.4454 ± 0.2640 %, substances soluble in ethanol of 70° G.L. 16.8035 ± 0.7730, substances soluble in ethanol of 50° G.L. 16.0179 ± 0.3120, and water soluble substances 5.7206 ± 0.6862, were within the permissible range according to the pharmacopoeias; in the determination of heavy metals, we obtained concentrations of arsenic 0.1657 ± 0.015 ppm, mercury 0.0438 ± 0.005 ppm, lead 0.0032 ± 0.001 ppm and copper 0.0355 ± 0.002 ppm; in the phytochemical screening, we identified the presence of reducing sugars, phenols, amino acids and flavonoids as anthocyanidins. Likewise, the content of anthocyanins in the fruit was quantified obtaining a concentration of 10.7117 mg of cyanidin 3-glucoside/g.
