Pharmacognostical studies of important arid zone plants

Abstract

RESUMO: "Estudos farmacognósticos de plantas importantes de zonas áridas". A zona árida de Rajasthan, Índia, é importante pela grande diversidade e especificidade de plantas endêmicas de importância econômica e medicinal. Destas, três plantas de zonas áridas, Gisekia pharnaceoides L., Gisekiaceae, Sericostoma pauciflorum Stocks ex Wight, Boraginaceae, e Trianthema decandra L., Aizoaceae, que são tradicionalmente utilizados para diversas doenças (hepatite, asma, icterícia, infecções da pele etc.), foram selecionados para o estudo. Neste trabalho trabalho, a avaliação farmacognóstica detalhada destas espécies, através de estudo morfoanatômico, determinações físico-químicas e parâmetros fitoquímicos, foram realizados. As características morfológicas podem ser utilizados para rápida identificação das drogas, particularmente no caso de materiais em pó, e possivelmente ajudar a diferenciar a droga de outras espécies.Unitermos: Plantas de zona árida, Gisekia pharnaceoides, Sericostoma pauciflorum, Trianthema decandra, avaliação farmacognóstica.ABSTRACT: Arid zone of Rajasthan, India, has its own importance, great diversity and specific characteristic with respect to endemic and large number of plants of economic importance and medicinal use. Out of these, three arid zone plants Gisekia pharnaceoides L., Gisekiaceae, Sericostoma pauciflorum Stocks ex Wight, Boraginaceae, and Trianthema decandra L., Aizoaceae, which are traditionally used for different ailments (hepatitis, asthma, jaundice, skin-infections etc.) have been selected for the study. In the present paper, detailed pharmacognostical evaluation of these plant species using microscopy, standard physicochemical determinations and authentic phytochemical parameters has been carried out. Later on, these morphological characteristics could be used for rapid identification of the drugs, particularly in case of powdered materials, and may possibly help to differentiate the drug from its other species.
