Abstract
El presente trabajo tuvo como principal objetivo desarrollar un labial en barra a base de extracto hidroalcohólico del fruto de Vaccinium corymbosum y evaluar su actividad antioxidante in vitro. La obtención del colorante se realizó por el método de extracción solido-liquido de antocianinas, luego se concentró el extracto y se desarrolló el labial en barra el cual fue sometió a diferentes pruebas de evaluación de calidad organolépticas, fisicoquímicas y microbiológicas.
Después se determinó al labial en barra desarrollado, su capacidad antioxidante in vitro con el 2,2, difenil-1- picrilhidrazilo (DPPH), el resultado de la capacidad antioxidante fue expresado en porcentaje de reducción del DPPH. Los resultados obtenidos del control organoléptico del labial en barra de Vaccinium corymbosum, en el tiempo 0, a los 5 días y 10 días no mostraron diferencia y los parámetros fisicoquímicos se encuentran dentro del rango aceptable según diversos estudios, así mismo los análisis microbiológicos mostraron resultados dentro de los límites de aceptabilidad. El resultado de la capacidad antioxidante fue de 14,23 ± 0,53 en 4 mg de labial en barra de Vaccinium corymbosum.
Se concluye que el labial en barra tiene capacidad antioxidante y también cumple con los parámetros de calidad establecidos por organismos internacionales.
ABSTRACT The present work had as main objective to develop a lipstick based on hydroalcoholic extract of the fruit of Vaccinium corymbosum and evaluate its antioxidant activity in vitro. The dye was obtained by the method of solid-liquid extraction of anthocyanins, then the extract was concentrated and the lipstick was developed which underwent different organoleptic, physicochemical and microbiological quality assessment tests. After the developed lipstick was determined its antioxidant capacity in vitro with 2,2, diphenyl-1- picrylhydrazyl (DPPH), the result of the antioxidant capacity was expressed as a percentage reduction of DPPH. The results obtained from the organoleptic control of the Vaccinium corymbosum lipstick, at time 0, at 5 days and 10 days showed no difference and the physicochemical parameters are within the acceptable range according to various studies, likewise microbiological analyzes showed results within of the limits of acceptability. The result of the antioxidant capacity was 14.23 ± 0.53 in 4 mg of Vaccinium corymbosum lipstick. It is concluded that lipstick has antioxidant capacity and also meets the quality parameters established by international organizations.
