Foi avaliada a morfogênese in vitro a partir de explantes de folha imatura excisados de plantas de duas variedades nacionais (RB739735 e RB72454) de cana-de-açúcar (Saccharum officinarum L.), mantidas em campo. Os explantes foram obtidos de plantas com 6-9 meses e cultivados em meio MS sólido suplementado com 2,4-D a 9 miM. As culturas foram mantidas no escuro, durante quatro semanas. A eficiência de formação de calos foi influenciada pelo genótipo. Os calos derivados da variedade RB72454 eram mucilaginosos e não originaram plantas. Explantes da variedade RB739735 formaram calos amarelos friáveis e embriogênicos (tipo II), que mantiveram sua capacidade proliferativa por, pelo menos, seis meses. Após transferência para meio MS sem reguladores de crescimento...

Abstract Passiflora species are well known for their common use in popular medicine for the treatment of several diseases, such as insomnia, anxiety, and hysteria, in addition to their anti-inflammatory, antioxidant, analgesic and antibacterial potential. However, few data about the chemical composition and the medicinal potential of in vitro derived materials are available. Therefore, the goal of this work was to compare, for the first time, the phytoconstituents of in vitro derived materials of four Passiflora species, and evaluate the antibacterial potential of their extracts against 20 Gram-positive and negative strains. Chromatographic analysis indicated the presence of saponins in roots extracts from all studied species, whereas leaf extracts...

ABSTRACT Casearia genus (Salicaceae) is found in sub-tropical and tropical regions of the world and comprises about 160-200 species. It is a medicinal plant used in South America, also known as “guaçatonga”, “erva-de-tiú”, “cafezinho-do-mato”. In Brazil, there are about 48 species and 12 are registered in the State of Rio de Janeiro, including Casearia sylvestris Sw. There are many studies related to the chemical profile and cytotoxic activities of extracts from these plants, although few studies about the antifungal potential of the essential oil have been reported. In this work, we have studied the antifungal properties of the essential oil of C. sylvestris leaves, as well as of their fractions, against four yeasts (Saccharomyces cerevisae, Candida...
