ABSTRACT
The plant species Solanumlycocarpum, 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. We obtained an average grade of 9.90% loss on the drying, total ash of 7.91% and 0.37% of ash insoluble in acids. . For the substances extractable through alcohol, the average content found was 14.479% for the Soxhlet extraction method and 0.987% for the cold extraction method. This data can be used in the identification and quality assurance of the plant drugs of Solanum lycocarpum for the production of new herbal medicines.
