Herbal medicines based on Ginkgo biloba L. and Bacopa monnieri L. are used to improve memory and cognitive function. The quality control and anticholinesterase activity of the herbal medicines prepared from G. biloba and B. monnieri were evaluated which are commercialized in handling pharmacies. Samples of herbal medicines based on G. biloba and B. monnieri were obtained from handling pharmacies in Teresina-PI, submitted to labeling analysis and anticholinesterase activity. The phytochemical study was performed by preliminary prospecting, TLC and HPLC. The tests physicochemical and microbiological analyses were made according to the Pharmacopoeia 2010. It was observed that the labeling, foreign material, disintegration, and microbiological parameters were in accordance with ANVISA standards. The colorimetric tests were uniform in the samples of B. monnieri and variable of G. biloba. The average weight evaluation shows that the G1 and B3 samples have capsular content above that described in the labeling and presented pH values ​​different. Among the thermogravimetric profiles, the mass losses of samples G1 and B3 showed values ​​with high ash content, suggesting adulterations. Phytochemical prospecting showed flavonoids as common secondary metabolites in both species, corroborating with TLC and HPLC analysis, which identified the compounds chlorogenic acid, rutin, myricetin and quercetin. The samples G4, B2 and B5 present metabolites capable of inhibiting the enzyme acetylcholinesterase with IC50 of 0.8540 mg/mL, 0.9650 mg/mL and 1.8221×10-5 mg/mL, respectively. The samples G1 and B3 of G. biloba and B. monnieri, did not obey some parameters of quality control for herbal medicines according to the criteria of the Brazilian Pharmacopeia.

Abstract. In this study two approaches are presented to identify Dominant Runoff Processes (DRP) with respect to regionalization. The approaches are a simplification of an existing method to determine DRP by means of an extensive field campaign. The first approach combines the permeability of the substratum, land-use and slope of the basin in a GIS-based analysis. The second approach makes use of discriminant analysis of the physiographic characteristics of the basin and links it to the GIS analysis. The results of the developed approaches are maps, which identify dominant runoff processes and represent a spatial distribution of the hydrological behaviour of the soil during prolonged rainfall events. The approaches have been developed in a micro-scale basin (Germany). An additional meso-scale basin was introduced in which the two approaches were applied for quality control. The thus generated maps for the micro-scale basin were compared with an existing DRP map, which was derived with the existing method. The first approach showed a resemblance of 79% when compared to this map, whereas the second approach showed only a resemblance of 51%. The generated maps for the meso-scale basin were compared to DRP that were determined point wise according to the existing method. The first approach showed in this case a resemblance of 81%, whereas the second approach showed a resemblance of 68%. Therefore, the first approach is preferred to the second approach when accuracy, data input and calculation time are concerned.
