Description

The quality control of the vegetable material, presence and concentration of the active principles of Justice pectoralis and Lippia alba were studied for the use and marketing as herbal products. The method of analysis of the Justice pectoralis and Lippia alba was carried out by means of proton nuclear magnetic resonance spectroscopy and the gas chromatography. Coumarin and essential oils were determinate in the plants extracts. Different samples were collected throughout one year to evaluate the variation of concentration of the active principles of the plant and there was evaluated a method of extraction of solvents

Abstract (Spanish)

El control de calidad del material vegetal, presencia y concentracion de los principios activos de Justicia pectoralis y Lippia alba fueron estudiados para el uso y comercializacion como productos herbarios. El metodo de analisis de la Justicia pectoralis y Lippia alba se realizo por medio de espectroscopia de resonancia magnetica nuclear de proton y la cromatografia de gases. Cumarina y aceites esenciales se determinaron en los extractos de las plantas. Diferentes muestras se recolectaron durante un ano para evaluar la variacion de concentracion de los principios activos de la planta y se evaluo un metodo de extraccion de disolventes
