New Sulphated Flavonoids and Larvicidal Activity of Helicteres velutina K. Schum (Sterculiaceae)

et al. 2018

View full text Add to dashboard Cite

Helicteres velutina K. Schum (Sterculiaceae), commonly known in Brazil as ‘pitó’, is traditionally used by indigenous peoples as insecticides and repellents. The present work reports on the the phytoconstituents from aerial parts of H. velutina and evaluation of the larvicidal potential of its extract. The compounds were isolated using chromatographic techniques and identified by NMR, IR and LC-HRMS. This study led to the isolation of a fatty acid, one aliphatic alcohol, four chlorophyll derivatives, one steroid, triterpenes, a lignan, and flavonoids, highlighting the new compounds in the literature, 5,4′-di-hydroxy-7-methoxy-8-O-sulphate flavone (mariahine) (15a) and 5,3′-di-hydroxy-7,4′-dimethoxy-8-O-sulphate flavone (condadine) (15b). The work presented here contributes to the chemotaxonomic knowledge of the Sterculiaceae family by describing the occurrence of sulphated flavonoids in this family for the first time. The crude ethanolic extract of H. velutina featured robust larvicidal activity against Aedes aegypti larvae, showing that the extract can be useful as a domestic larvicide, just as indicated by traditional use, to combat A. aegypti, a vector insect of severe viral diseases, such as dengue and Zika.

The genus Elaeocarpus belongs to the Elaeocarpaceae family. It consists of about 350 species distributed in the tropical and subtropical regions. Plants in the genus, reportedly, contain compounds known for various biological activities such as affinity for the δ-opioid receptor, antioxidant, cytotoxicity and antimicrobial activities. Elaeocarpus floribundus, commonly known in India as 'Indian Olive' is a medicinal plant widely distributed through Eastern Asia and the pacific. In this study, we report the isolation and spectroscopic characterization of fifteen compounds (1-15) and an additional three compounds (16-18) were obtained as mixtures. This includes three fatty acids, three diterpenoids, one triterpene alcohol, two fatty alcohols, three phaeophytins, two phytosterols, one sesquiterpene, and three hydrocarbons from the hexane extract of the leaves. Compounds 1-18 are reported for the first time from this source. To the best of our knowledge, this is an initial report of the isolation of compounds 1-11, and 14-18 from the genus Elaeocarpus.

A versatilidade produtiva do facheiro associada a disponibilidade natural da espécie ocasionam uma exploração sem planejamento. Consequentemente, poucos estudos tem sido desenvolvidos sobre a conservação e manutenção da espécie, principalmente na Região Nordeste. O objetivo do presente estudo foi avaliar o efeito do meio simplificado e do agente gelificante alternativo, amido de milho, na germinação in vitro de Pilosocereus pachycladus. As sementes foram desinfestadas e inoculadas em meio de cultivo contendo fertilizantes comerciais, suplementados com sacarose, e gelificados com ágar e amido de milho. Os tratamentos: sais completo de Calcinit® e Kristalon® e gelificado com ágar - CKAG; metade dos sais de Calcinit® e Kristalon® e gelificado com ágar – MCKAG; sais completo de Calcinit® e Kristalon® e gelificado com amido de milho - CKAM; metade dos sais de Calcinit® e Kristalon® e gelificado com amido de milho - MCKAM. O meio CKAG promoveu menor percentual de contaminação 20%. E os meios CKAM e MCKAM obtiveram 67 e 75% para percentual de germinação respectivamente. As maiores médias para altura da parte aérea foi para os meios CKAM e CKAG com 0,32 e 0,30 cm respectivamente. E para o comprimento da raiz o maior valor foi para o meio CKAG com 0,65 cm. Não houve efeito significativo na aclimatação das plântulas para os tratamentos. Diante os resultados obtidos sugere-se a utilização do amido de milho em meios de cultura como uma excelente alternativa na germinação in vitro de P. pachycladus, proporcionando redução nos custos e um percentual de germinação satisfatório.
