“…Hymenaea parvifolia Huber., conhecida popularmente por jutaí, jutaí-mirim, jatobá, jatobá-do-cerrado ou jatobazinho, é árvore frutífera nativa da Amazônia utilizadas alimentação humana e animal, na medicina popular, na cremagem de látex de seringuira e na indústria madeireira (Ishibashi et al, 1999;Coelho-Ferreira, 2009;Rai et al, 2012).…”

Recebido para publicação em 29/09/2015 Aceito para publicação em 02/01/2016 RESUMO: O objetivo do presente trabalho foi avaliar a influencia do tamanho e da temperatura na germinação das sementes, assim como, da posição de escarificação do tegumento e a profundidade de semeadura na emergência de plântulas de jutaí. As sementes foram separadas em três grupos: sementes pequenas, médias e grandes. A germinação das sementes foram realizadas nas temperaturas de 5, 10, 15, 20, 25, 30, 35, 40 e 45 °C e com fotoperíodo de 12 horas. As sementes escarificadas foram colocadas para germinar em 0, 2, 4 e 6 cm de profundidade de semeadura. As sementes médias e grandes apresentaram maiores porcentagens e índices de velocidade de germinação. A faixa de temperatura ótima de germinação está entre 25 e 35°C. A escarificação no hilo da semente ou não é adequada para quebra de dormência de sementes de jutaí. Profundidades de semeadura iguais ou superiores a 4 cm são inadequadas para a emergência de plântulas de jutaí.Palavras-chave:Leguminosae,tamanho de semente,temperatura, escarificação do tegumento, profundidade de semeadura. ABSTRACT: Seed germination and emergence of jutai (Hymenaea parvifolia Huber.)seedlings. The objective of this study was to evaluate the influence of seed size and temperature on seed germination, as well as the scarification position of the tegument and sowing depth on the emergence of jutai seedlings. The seeds were separated into three groups: large, medium and small. The temperatures to which the seeds were subjected for germination were 5, 10, 15, 20, 25, 30, 35, 40, and 45°C under a photoperiod of 12 hours. The scarified seeds were placed to germinate at depths of 0, 2, 4, and 6 cm. Seed germination was affected by seed size (large and medium seeds). The optimum temperature range was found to be between 25 and 35°C. The scarification in the hilum or the tegument was enough to break the dormancy of the jutai seeds. Sowing depths equal to or deeper than 4 cm were found to be inadequate for the emergence of jutai seedlings.

“…A mixture of triterpenes was isolated from the aerial parts of L. camara by open column chromatography. The components of this mixture were subjected to highperformance liquid chromatography (HPLC) analysis and separation, which yielded two white amorphous solids with HR-DART-MS m/z 569.38421 (C 35 H 52 O 6 [M + H] + ). NMR experiments ( 1 H, 13 C, COSY, HSQC, and HMBC) were acquired for both structures (Figures S1-S10).…”

Astilbin was isolated in high yield from Dimorphandra mollis, and its insecticidal and growth inhibiting activity by stomach ingestion were evaluated against Anticarsia gemmatalis and Spodoptera frugiperda. The insecticidal activity of astilbin, the weight reduction of the larval phase and the prolongation of the larval and pupal phases were verified for both species. Astilbin was identified on the base of its NMR, MS and physical data.
