Abstract

Context: Viola tianschanica Maxim. (Violaceae) is a perennial herb widely distributed in Central Asia, especially in the Xinjiang of China. The whole herb has been used in traditional Uygur medicines as an antifebrile-detoxicate drugs.

Aims: To characterize macroscopical and microscopical features of the root, leave and rhizome of the V. tianschanica Maxim. Explore and establish the micro-morphology and quality control methods for this plant.

Methods: Pharmacognostic and phytochemical investigations were conducted regarding macroscopic, microscopic and preliminary phytochemical parameters.

Results: It can be identified by structural features of flowers, structural characteristics of rhizome and root, specific thickening of endothecium cells of clinandrium can be regarded as identification character. This crude drug showed the characteristic physicochemical values like total ash (12%), water soluble ash (4.0%), acid insoluble ash (3.8%) and moisture content (6.5%). The ethanolic extract mainly contained flavonoids in this herb, also contained alkaloids, tannins, saponins, coumarin and absence of fats and protein.

Conclusions: Various pharmacognostic and preliminary phytochemical characters observed in this test may help in standardization, identification and carrying out further research in V. tianschanica Maxim. based drugs used in Uygur traditional medicine and folk medicines. Sediment type of impurity content is higher in herbs; it should be paying attention to control quality of medicinal materials or drugs.

Keywords: Macromorphology; micromorphology; pharmacognostical identification; Viola tianschanica Maxim.

Resumen

Contexto: Viola tianschanica Maxim. (Violaceae) es una hierba perenne ampliamente distribuida en Asia Central, especialmente en Xinjiang, China. Esta hierba se ha utilizado en la medicina tradicional Uygur como antifebrífugo-desintoxicante.

Objetivos: Caracterizar las peculiaridades macroscópicas y microscópicas de la raíz, hojas y rizoma de V. tianschanica Maxim. Analizar y establecer los métodos de micro-morfología y control de calidad de esta planta.

Métodos: Las investigaciones farmacognósticas y fitoquímicas se llevaron a cabo en relación con los parámetros macroscópicos, microscópicos y fitoquímicos preliminares.

Resultados: La planta puede ser identificada por las características estructurales de las flores, del rizoma y la raíz, engrosamiento específico de células de endotecio del clinandrio puede ser considerado como carácter de identificación. Esta droga cruda mostró valores fisicoquímicos característicos como ceniza total (12%), ceniza soluble en agua (4,0%), ceniza insoluble en ácido (3,8%) y contenido de humedad (6,5%). El extracto etanólico contenía principalmente flavonoides, también contenía alcaloides, taninos, saponinas, cumarina y ausencia de grasas y proteínas.

Conclusiones: Varios caracteres farmacognósticos y fitoquímicos preliminares, observados en este ensayo, pueden ayudar en la normalización, la identificación y la realización de más investigaciones en preparados basados en V. tianschanica Maxim utilizados en la medicina tradicional Uygur y medicamentos populares. El tipo de sedimento del contenido de impurezas es mayor en las hierbas; se debe prestar atención al control de calidad de las materias medicinales o drogas vegetales.

Palabras Clave: Identificación farmacognóstica; macromorfología, micromorfología; Viola tianschanica Maxim.
