Antiproliferative effect of Pterogyne nitens on melanoma cells

As part of our program of bioprospecting for novel antitumor drug prototypes, twenty extracts and fractions obtained from Pterogyne nitens Tul. (Fabaceae, Caesalpinioideae) were screened for antiproliferative activity against B16F10 murine melanoma cells, by the MTT colorimetric assay. The strongest activity was found in EtOAc fractions from the flowers (IC50 = 0.35 µg/mL), fruits (IC50 = 0.34 µg/mL), leaves (IC50 = 0.33 µg/mL) and stems (IC50 = 0.29 µg/mL). Analysis by TLC and HPLC-DAD showed the presence of guanidine alkaloids, flavones and flavonols in the bioactive samples. Additionally, a phytochemical study of the EtOAc fraction of the stems afforded quercetin (1) and isoquercitrin (2), two flavonols with antiproliferative activity previously described in the literature. On the basis of these results, it can be concluded that P. nitens inhibits the growth of melanoma cells in vitro. Further investigations will be needed to assess the usefulness of the samples under study for the treatment of neoplasms and to characterize other bioactive compounds. Keywords: antiproliferative; Pterogyne nitens; Caesalpinioideae; melanoma; flavonoids; Fabaceae.

Etnobotânica de Leguminosae entre agricultores agroecológicos na Floresta Atlântica, Araponga, Minas Gerais, Brasil

This study describes the richness of Leguminosae used by 21 traditional farmers in coffee agroforestry systems (AFS) and forest fragments of the Atlantic Forest, in the municipality of Araponga, Minas Gerais, Brazil. It also presents the use categories, relative importance and the species similarity between the AFSs. Data were collected through semi-structured interviews and participant observation, between August 2005 and November 2006, directed during random walks in seven AFSs and forest fragments surrounding the State Park of Serra do Brigadeiro. The farmers cited 59 species of Leguminosae, of which 86% are native to the Atlantic Forest and used in ancient cultural practices, such as to make bullock carts. Twelve categories of use were established, among them the most important were fertilizer and firewood (21 spp each); in the AFSs, species used for soil fertilization (18 spp) are the most utilized, and in the forest, the species for firewood and technology (17 spp.) The relative importance index showed that in the forest, Piptadenia gonoacantha showed 83% of agreement for the use as wood for fencing pastures, while in the AFSs, Inga edulis scored 100% as food. The AFSs studied show little similarity of species (0.42 of the Sorensen scale), due to the selection promoted by the farmers, thus, providing room for the conservation of useful species of Leguminosae.

Description of a new species of Neoparaphytoseius Chant and McMurtry (Acari: Mesostigmata: Phytoseiidae) from Peru, with a redefinition of the genus

Neoparaphytoseius charapa n. sp. is described, based on the morphology of adult females and males collected on Inga edulis ( Mart.) ( Fabaceae) in northeastern Peru. Neoparaphytoseius Chant & McMurtry is redefined on the basis of the new species and re-examination of its type species N. sooretamus Chant & McMurtry.
