Considering the worldwide consumption of coffee, it is natural that throughout the history many people have dedicated the research to markers that contribute somehow on gauging its quality. This research aimed to evaluate the biochemical performance of arabica coffee during storage. Coffee in beans (natural) and in parchment (pulped) dried in concrete terrace and in dryer with heated air were packed in jute bags and stored in not controlled environmental conditions. Enzymatic activities of superoxide dismutase, catalase, peroxidase, polyphenoloxidase, esterase and lipoxygenase in coffee grains were evaluated at zero, three, six, nine and twelve months by means of electrophoresis. Independently of the drying method, the activity of isoenzymatic complexes highlighted deteriorative processes in stored grains of coffee. The treatments 60/40º C and 60º C used to reduce the water content imposed a greater stress condition, accelerated metabolism of natural coffee in the storage with decreased activity of defense mechanisms due to latent damage in these grains. Natural coffees are more sensible to high drying temperatures and its quality reduces faster than pulped coffee in the storage.

During the production process of leather a lot of water is used. In addition, companies such as tanneries have high pollution potential. The effluent that is not properly treated , and it is irregularly released in water bodies can cause negative impacts to the environment and generate fines. The aim of this paper is to present the importance of environmental valuation in the effluent treatment system of a tannery, in order to add social and economic development with preservation of environmental quality. A valuation of inputs and outputs of the effluent treatment process from Tannery Bull in Presidente Prudente was made, as well as a proposal to improve the treatment and its valuation. Many of these industries do not account the costs from the effluent treatment and end up spending what could have been avoided. The management of environmental costs promotes sustainable development. Thus, we can conclude that, if there were better control and also an improved management of the tannery, the proposed treatment would bring economic improvement to the company and specially it would not cause much impact on the environment, including improving the quality of life in the region

CHEMICAL CONSTITUENTS OF Hyptidendron canum (Pohl ex Benth.) R. Harley (LAMIACEAE). Chemical investigation of Hyptidendron canum stems resulted in the isolation of betulinic, ursolic and euscaphic acids. From the leaves were isolated 3β-O- β-galactopiranosilsitosterol, ursolic aldehyde, and mixtures of maslinic acid and 2α-hydroxyursolic acid, α and β-amyrin, uvaol and erythrodiol, sitosterol and stigmasterol, spathulenol and globulol. Hexane and chloroform leave fractions as well as ursolic and betulinic acids showed antifungal activities against the yeast form of Paracoccidioides brasiliensis.
