“…However such previous studies did not document the direction of knowledge (homogeneity or heterogeneity). Rokaya et al, (2014) have showed the diversity and importance of medicinal plants used to treat gastro-intestinal disorders in the traditional health care system of Nepal. They have documented highest number of species for treatment of disease like diarrhea, stomach-ache and dysentery.…”

Abstract:In the present study the top down approach has been utilized to quantify homogeneity of ethno-knowledge, frequency of species utilized for a disease related to a specific system as well as identification of corporeal system that are outliers with aim to identify the species and their usefulness for a specific disease that make the system as outlier. The study was carried out for medicinal plants of arid and semiarid region of the Indian Thar area. Three statistical parameters namely, evenness, frequency distribution and regression and residual value analysis were utilized. The study revealed that ethno-medicinal knowledge about 136 species were related with 12 different corporeal systems and frequency distribution classified these 136 species and 12 corporeal systems under 9 different classes. Maximum numbers of taxa are recorded for skeletal, muscle and connective tissues (114) followed by the digestive system (111) and skin and sub-cutanuous system (89). Homogeneity of ethnic-knowledge are restricted for few corporeal systems like respiration, fever, blood and hematopoietic organ, central nervous system, genito-urinary system and circulatory systems, while random and clumped types knowledge distribution were recorded for other corporeal systems. Platykurtic and leptokurtic types of distributions were observed for different corporeal systems. Through use of standard residuals analysis of medico-ethnic-knowledge, digestion system was designated as positive outliers while fever and genito-urinary systems were the negative outliers. Further regression analysis has revealed that with in this region ethnic knowledge about the medicinal properties of a species is largely associated with the regional abundance of taxa.

“…Tal finalidade pode ser atribuída à presença de taninos, já que estes possuem ação antibacteriana, antifúngica e antiviral. Essas atividades são devido à habilidade dos taninos de complexarem com macromoléculas, como proteínas e polissacarídeos (Simões et al, 2007).…”

“…Pela sua riqueza química e farmacológica, têm sido alvo de crescentes estudos com o objetivo de comprovar atividades atribuídas pelas crenças populares ou mesmo obter novos compostos ativos (Menendez-Baceta et al, 2015). O uso de medicamentos fitoterápicos está se tornado popular pois, quando feito de forma adequada, apresenta pouco ou nenhum efeito colateral, quando comparado aos medicamentos tradicionais; além disso, as plantas medicinais têm sido amplamente usadas em cosméticos e nutracêuticos (Rokaya et al, 2014).…”

RESUMO:A espécie vegetal Solanum lycocarpum, Solanaceae, popularmente conhecida como lobeira, está distribuída por todo o Brasil, principalmente em áreas do cerrado. Estudos comprovam que os frutos possuem diversas atividades e, atualmente, estão sendo utilizados no tratamento da diabetes. As folhas são utilizadas popularmente contra afecções das vias urinárias, cólicas abdominais e renais, espasmos e epilepsia, porém são poucos os estudos científicos que verificam as atividades farmacológicas das folhas. Assim, torna-se necessária a determinação de parâmetros anatômicos, físico-químicos e fitoquímicos que auxiliarão em futuras identificações e controle de qualidade da droga vegetal. Neste estudo foi realizada a coleta, secagem e pulverização das folhas de Solanum lycocarpum para a obtenção da droga vegetal e posterior caracterização desta. As análises microscópicas do pecíolo, nervura central e mesofilo revelaram características típicas da família Solanaceae, observando-se um sistema vascular bicolateral e a presença de areia cristalina e tricomas estrelados. A triagem fitoquímica, constatou a presença de taninos, flavonoides, esteróides e triterpenos, cumarinas e saponinas. Obteve-se o teor médio de 9,90% de perda por dessecação, 7,91% de cinzas totais e de 0,37% de cinzas insolúveis em ácidos. Para as substâncias extraíveis por álcool, o teor médio encontrado foi de 14,479% para o método de extração por Soxhlet e 0,987% para o método de extração a frio. Assim, espera-se que esses dados possam ser utilizados na identificação e controle de qualidade da droga vegetal de Solanum lycocarpum para a produção de novos medicamentos fitoterápicos.Palavras chave:Solanum lycocarpum, parâmetros analíticos, Solanaceae.ABSTRACT: Determination of the anatomics, physical-chemicals and phytochemicals parameters of the Solanum lycocarpum A.St.-Hill leaves. The plant species Solanum lycocarpum, Solanaceae, most known as lobeira, are distributed throughout Brazil, especially in Cerrado areas. Studies show that the fruits own different properties and, currently, are being used in the treatment of diabetes. Even though the leaves are being used by the general population against urinary tract disorders, renal and abdominal cramps, spasms and epilepsy, there are few scientific studies that verify the possible pharmacological activities of leaves. This shows that it is necessary to research and determinate the anatomic, physical-chemicals and the phytochemicals parameters that are going to help in the identification and quality assurance of the drug. In this study the leaves of Solanum lycocarpum were collected, dried and pulverized in order to be obtained the plant drug for further characterization.. Microscopic analyzes of the petiole, midrib and mesophyll showed typical features of the Solanaceae family, by detecting a biocolateral vascular system and the presence of crystallines and and stellatetrichomes. In the phytochemical screening performed, the tanning, flavonoids, sterols and triterpenes, coumarins and saponins were found. ...
