          Abstract

          Resumo Apresentamos o levantamento florístico-taxônomico das espécies de Symplocaceae para o estado do Ceará, como parte do projeto “Flora do Ceará: conhecer para conservar”. O estudo foi baseado na análise comparativa dos caracteres morfológicos de espécimes depositados nos Herbários ALCB, EAC, HUVA, IPA, R e UPCB, bibliografias especializadas e imagens de coleções-tipo. Para o estado foram registradas três espécies de Symplocos: S. guianensis, S. nitens e, possivelmente, S. oblongifolia. No entanto, por falta de material reprodutivo não foi confirmada a identificação do último táxon. As espécies ocorrem em vegetação de Floresta Ombrófila Densa e Savana. Symplocos nitens é uma nova ocorrência para o Ceará e foi registrada em duas Unidades de Conservação no estado.

          Abstract We perform the taxonomic floristic survey of Symplocaceae for the state of Ceará, as part of the “Flora of Ceará: knowing to conserve” Project. The study was based on the comparative analysis of morphological characters of specimens from herbaria ALCB, EAC, HUVA, IPA, R and UPCB, specialized bibliography, as well as photos of type-collections. For the state three species of Symplocos were registered: S. guianensis, S. nitens and, probably, S. oblongifolia. However, due to a lack of reproductive material, the identification of the last taxon was not confirmed.The species occur in Dense Ombrophilous Forest and Savanna. Symplocos nitens is a new occurrence for Ceará state and was recorded in two Conservation Units in the state.

            Phenolic glycosides from Symplocos racemosa: natural inhibitors of phosphodiesterase I.

            One new phenolic glycoside named benzoylsalireposide (1) along with one known phenolic glycoside named salireposide (2) have been isolated from Symplocos racemosa. Four other known compounds i.e. beta-amyrin (3), oleonolic acid (4), beta-sitosterol (5) and beta-sitosterol glycoside (6) were also isolated from this plant. The structure elucidation of the isolated compounds was based primarily on 1D- and 2D-NMR analysis, including COSY, HMQC, and HMBC correlations. The compound 1 and 2 showed inhibitory activity against snake venom phosphodiesterase I.

              Anti-AIDS agents. 46. Anti-HIV activity of harman, an anti-HIV principle from Symplocos setchuensis, and its derivatives.

              Matairesinol (1) and harman (5), identified from Symplocos setchuensis, were found to inhibit HIV replication in H9 lymphocyte cells. Anti-HIV evaluation of 28 derivatives of 5 revealed that compound 19 showed potent activity with EC(50) and therapeutic index values of 0.037 microM and 210, respectively.
