Características anatômicas de espinheira-santa (Maytenus ilicifolia Mart. ex Reissek e Maytenus aquifolia Mart.) e mata-olho (Sorocea bonplandii (Baill.) Burg. Lanj. & Boer.) para o controle de qualidade da matéria prima

Maytenus ilicifolia and Maytenus aquifolia (Celastraceae) both designated espinheira-santa have proven anti-ulcer activity. Morphologic similarities between leaves of espinheira-santa and mata-olho (Sorocea bonplandii), has motivated fakes in the market of phytotherapy. The present work consisted of the anatomical study, including stem and leaf, of the species M. ilicifolia, M. aquifolia and S. bomplandii. Samples of adult leaves and stem of plants located in the cities of Maringá and Marialva were collected. Both are located in the northwest region of Paraná State. The botanical material was prepared with using usual techniques of anatomy. The leaves of both Maytenus species presented great similarities, characterizing itself for the presence of epidermal cells with straight walls, biseriate palisade tissue, petiole vascular system represented by unique amphicribal bundle and sclereids, which were present in the stems of these two species. S. bomplandii leaves differed of Maytenus species for presenting epidermal cells with undulated walls, uniserite palisade tissue, petiole vascular system represented by many collateral bundles and gelatinous fibres. Non-glandular trichomes, glandular trichomes, and laticifer only occur in S. bomplandii.

Processo de uso e ocupação do Pontal do Paranapanema-SP: perspectiva das unidades de conservação (UCs)

The current concern with environmental issues by the scientific community, governmental and civil society also brings out the need to recover, preserve and conserve the environment. With this understanding, this work was prepared, which had as one of the main objectives of the historical process of land use and occupancy of the Pontal, since the nineteenth century to the present day. From this, the changes were evident in the types of land use, which rose from native forest to plant crops (permanent and temporary crops) and later as pasture. Through this process of occupation, exploitation of forests and replacement even three, Reserves being brought from the Far West Paulista, through the state government of Sao Paulo, they were almost decimated. Such areas decreed by law to be preserved and conserved, with the rampant occupations, were suffocated by the fakes and illegal occupation of land tenure contracts, leaving the region currently only a few forest fragments and protected areas of State Park Morro do Diabo, PRNP Boa Vista and Ecological Station Black Lion Tamarin. Furthermore, the article emphasizes the main legislation being developed by federal and state levels aimed at protecting natural resources and the effectiveness they had with the passage of time, demonstrating that the conservation of the environment, has several contributions in the law, however, and they are so vast that hinder its application.
