【 摘 要 】

Ipomoea pes caprae (L.) R. Br., (Convolvulaceae), a pantropical stand plant, popularly known as "salsa-da-praia", is used in folk medicine because of its analgesic, antinflammatory and healing properties. Protocols were developed from the fresh aerial plants to establish their previous treatment and quality control in order to get it characterized as a pharmaceutical raw material. The loss of water on drying in an air oven, showed that leaves represent a lesser dried mass yield than branches, as a result of its higher water content. Drying and milling were aimed at keeping the loss on drying below the limit value accepted for herbs. Dried and milled leaves and branches were classified as thick powder through the sieving method, before they were characterized according to pharmacopoeial tests for herbs. The determination of ashes indicated the presence of inorganic materials, most probably due to sand content which came from the herb habitat. The soluble water extractives were greater from the leaves, followed by the branches and proportional for the entire plant. These results showed to be correlated to the total flavonoid content. The thin layer chromatography for the hydroethanolic solutions only demonstrated differences related to the spots color intensity, and indicated the presence of isoquercitrin, being more evident from the leaves.
