| Pera glabrata (Schott) Baill. was selected for this study after showing a preliminary positive result in a screening of Atlantic Forest plant species in the search for acetylcholinesterase inhibitors and antifungal compounds. The bioassays were conducted with crude ethanol extract of the leaves using direct bioautography method for acetylcholinesterase and antifungal activities. This extract was partitioned with hexane, chloroform and ethyl acetate solvents. The active chloroform fraction was submitted to silica gel chromatography column affording 12 groups. Caffeine, an alkaloid, which showed detection limits of 0.1 and 1.0 µg for anticholinesterasic and antifungal activities, respectively, was isolated from group nine. After microplate analyses, only... |

| The assimilis species group is one of the several assemblages that can be distinguished within the genus Apostolepis. The group is characterized by a uniform red dorsal pattern, broad nucho-cervical collars, enlarged light snout blotch, dark ventral head, and entirely black terminal shield. A new species is here recognized as a member of the assimilis group and its phylogenetic relationships to A. assimilis and A. cearensis is inferred by means of cladistic analysis. Apostolepis ammodites sp. nov. can be easily diagnosed from all congeners by many autapomorphies and an exclusive combination of features. Comparative data are presented on scalation, coloration, dentition, osteology, and geographic distribution, with some notes on feeding and reproductive... |

| Elaboramos uma lista das espécies de répteis do Estado de São Paulo com base nos registros confirmados de exemplares depositados nas três maiores coleções científicas do estado, complementando esta informação com a bibliografia disponível. Registramos a presença de 212 espécies de répteis no Estado de São Paulo, distribuídas em 23 famílias, incluindo 12 quelônios, três crocodilianos e 197 Squamata (142 serpentes, 44 "lagartos" e 11 anfisbenas). Destas, onze são endêmicas do Estado de São Paulo (Mesoclemmys cf. vanderhaegei, Amphisbaena sanctaeritae, Mabuya caissara, Mabuya macrorhyncha, Liotyphlops caissara, Liotyphlops schubarti, Corallus cropanii, Atractus serranus, Phalotris lativittatus, Bothropoides alcatraz, Bothropoides insularis). Entre os... |
