The present report consisted in determining the optimal method of extraction of total flavonoids from the flowers of Cordia lutea Lam. "Flower of overo" collected from the district of Cormot, province of Gran Chimú. The flowers of Cordia lutea Lam were collected. "Flower of overo" in the flowering season during the month of February - March, which were subjected to cleaning, selection, stabilization, spraying, screening and storage. The extraction of extracts was then carried out by different methods of extraction. From the extracts the total flavonoids were obtained, the total flavonoids were quantified by UV-visible spectrophotometry obtaining the results expressed as Quercetin. The optimum total flavonoid yield of flowers of Cordia lutea Lam. Was extracted by Soxhlet, obtaining a percentage of 2.42 ± 0.0012%

The objective of this research was to determine the physicochemical characteristics and determination of the relative percentage of the oxygenated and hydrocarbon components of the essential oil of the Lantana cámara L. "Santa Maria". The essential oil extraction of Lantana camara was carried out by means of the water vapor trapping method "Hydrodistillation". The performance was determined by the clevenger equipment where 0.4% of the essential oil present in the leaves of Lantana camara L. The organoleptic characteristics were determined (spicy taste, suigeneris odor, transparent yellow color and oily texture); Within the physicochemical parameters were found (density of 0.93880, pH 4, refractive index 1.48868, acid index 3.366); And the solubility was higher with respect to ethanol grade from (70 ° 80 ° 96 ° GL.) And complete in n-hexane and ethyl ether. Finally, the relative perce...
