ResumoJacquinia armillaris é uma espécie que ocorre no litoral nordeste e sudeste do Brasil em formações sujeitas a intenso processo de fragmentação. Para melhor entendimento da ecologia de J. armillaris em seu habitat natural esse trabalho avaliou a biologia reprodutiva dessa espécie na restinga do Parque Estadual Paulo César Vinha, Espírito Santo, Brasil. Por meio da descrição de eventos relacionados à floração, morfologia das flores, receptividade estigmática, sistema de reprodução, viabilidade polínica e comportamento dos visitantes florais, observou-se que Jacquinia armillaris apresenta características da síndrome de cantarofilia e visitação de dois grupos de Coleoptera: Carpophilus sp. (Nitidulidae) e Horistonotus sp. (Elateridae). Os dados também sugerem que a espécie é autocompatível, porém os testes de cruzamento revelam que a espécie depende da polinização promovida pelos visitantes florais. A espécie não apresentou agamospermia e crescimento clonal, o que somado a uma baixa produção de pólen viável, a síndrome de cantarofilia e outros rigores comuns em ambientes de restinga pode resultar em anos com baixa produção de frutos. Palavras-chave: Jacquinia, cantarofilia, biologia reprodutiva, restinga. AbstractJacquinia armillaris occurs in the coastal zone of Northeast and Southeast Brazil in greatly reworked estuarine landscapes. For a better understanding of the ecology of J. armillaris in its natural habitat, this study assessed the reproductive biology of this species in the restinga of Parque Estadual Paulo César Vinha, Espírito Santo, Brazil. According to the data on flowering, floral morphology, stigmatic receptivity, reproductive system, pollen viability, and behavior of floral visitors, Jacquinia armillaris showed characteristics of cantarophily syndrome and is visited by two Coleopteras: Carpophilus sp. (Nitidulidae) and Horistonotus sp. (Elateridae). The data suggest that the species is self-compatible. However, J. armillaris depends on pollination promoted by floral visitors. Absence of agamospermy and clonal growth, plus low viable production of pollen, cantharophily and common restinga rigor are discussed as responsible factors for low fruit set, consequently producing stochastic variation in seed recruitment. Key words: Jacquinia, cantarophily, reproductive biology, Brazilian sandy coastal plain. (Ståhl 2010; APG 2009; Källersjö & Ståhl 2003). Dentre as espécies desse gênero destaca-se Jacquinia armillaris Jacq., uma espécie restrita à vegetação pós-praia de restinga que ocorre no litoral Norte e Sudeste do Brasil e que, por seu porte arbustivo ou arbóreo (até seis metros de altura), se destaca nessa vegetação predominantemente reptante (Fabris et al. 1990;Garcia 1999 Mariana Andrich

“…This species is widely spread on the sandbanks of eastern Brazil, from the states of Espírito Santo to Santa Catarina. M. subsericea has edible fruits, being consumed in natura , and local population also use its wood for construction [1, 2]. Studies with species from the genus Manilkara indicated the presence of triterpenes [3], saponins [4], and flavonoids [5].…”

Manilkara subsericea (Mart.) Dubard (Sapotaceae) is popularly known in Brazil as “guracica.” Studies with Manilkara spp indicated the presence of triterpenes, saponins, and flavonoids. Several activities have been attributed to Manilkara spp such as antimicrobial, antiparasitic and antitumoral, which indicates the great biological potential of this genus. In all, 87.19% of the hexanic extract from fruits relative composition were evaluated, in which 72.81% were beta- and alpha-amyrin esters, suggesting that they may be chemical markers for M. subsericea. Hexadecanoic acid, hexadecanoic acid ethyl ester, (E)-9-octadecenoic acid ethyl ester, and octadecanoic acid ethyl ester were also identified. Ethanolic crude extracts from leaves, stems, and hexanic extract from fruits exhibited antimicrobial activity against Staphylococcus aureus ATCC25923. These extracts had high IC50 values against Vero cells, demonstrating weak cytotoxicity. This is the first time, to our knowledge, that beta- and alpha-amyrin caproates and caprylates are described for Manilkara subsericea.

“…The subtribe Lychnophorinae (Vernonieae, Asteraceae) is endemic to Brazil and many of their species are used in anti-infl ammatory preparations. However, other biological activities have been described such as antimicrobial and cytotoxic properties, especially for the Lychnophora and Eremanthus species (Santos et al, 2009;Keles et al, 2010). The phytochemical profi le of this subtribe indicates a predominance of sesquiterpene lactones and fl avonoids.…”

“…The genus Eremanthus Less comprises 27 species of trees and shrubs that are normally found in "cerrado" (Brazilian savanna), but E. crotonoides is an exception that can also be found in "restinga" (sandy coastal plains) (Santos et al, 2009). Studies carried out for species from this genus indicated the predominance of sesquiterpene lactones from the furanoheliangolide class (goyazensolide and eremantholide types) as their characteristic constituents (Vichnewski & Gilbert, 1972;Raffauf et al, 1975;Bohlmann et al, 1980Bohlmann et al, , 1981Bohlmann et al, , 1982Vichnewski et al, 1989;Rüngeler et al, 1998;Sacilotto et al, 2002;Sakamoto et al, 2005).…”

Abstract:The genus Eremanthus is recognized by the predominance of sesquiterpene lactones from the furanoheliangolide type, a class of substances extensively tested against cancer cell lines. Thus, the species E. crotonoides (DC.) Sch. Bip., Asteraceae, obtained on "restinga" vegetation was evaluated against U251 and U87-MG glioma cell lines using the MTT colorimetric assay. Dichloromethane fraction was cytotoxic to both glioblastoma multiforme cell lines. We then conducted UPLC-PDA-ESI-MS/MS analysis of the dichloromethane fraction, which allowed the identification of the sesquiterpene lactones centratherin and goyazensolide. The isolation of centratherin was performed using chromatographic techniques and the identification of this substance was confirmed according to NMR data. Cytotoxic activity of centratherin alone was also evaluated against both U251 and U87-MG cells, which showed IC50 values comparable with those obtained for the commercial anticancer drug doxorubicin. All the tested samples showed cytotoxic activity against glioblastoma multiforme cells which suggests that E. crotonoides extracts may be important sources of antiproliferative substances and that the centratherin may serve as prototype for developing new antiglioblastoma drugs.
