Chemical characterization by GC-MS and phytotoxic potential of non-polar and polar fractions of seeds of Dioteryx odorata (Aubl.) Willd. from Venezuelan regions

Abstract

Recebido em 22/5/12; aceito em 24/10/12; publicado na web em 12/3/13Dipteryx odorata (Aubl.) Willd. is a tall arboreal species native to Central and Northern South America. This paper describes the chemical characterization and phytotoxic potential of polar and non-polar extracts from D. odorata seeds. Structural determinations were accomplished by chemical derivatization and analyzed by GC/MS. The chemical composition of the non-polar fraction (hexane and dichloromethane) presented fatty acids as major constituent. Medium polar and polar fractions (ethyl acetate and ethanol: water) contained carboxylic acid and high 6,7-Dyhidroxycoumarin-β-D-glucopyranoside content, not previously reported for seeds of D. odorata. Extracts showed a significant level of phytotoxic activity, correlated to the content of coumarin derivatives, predominantly in the polar fraction.

Extração Supercrítica Com Utilização De Modificadores E Caracterização a Partir Da Semente De Cumaru (Dipteryx Odorata)

“…A cumarina é um composto formado por um anel aromático fundido em um anel lactona com potencial para utilização de herbicida (Oliveros-bastidas et al, 2013), perfumes, cosméticos, cigarros (Sullivan, 1982), anti-inflamatório (Leal et al, 2000) além de fins medicinais, como na prevenção e tratamento de edemas consequentes da radioterapia e vários tipos de câncer (Grötz et al, 2001;Mohler et al, 1994;Thornes et al, 1994).…”

Isolation of Flavonoids fromDipteryx odorataby High Performance Liquid Chromatography

“…1,2 Popularly, it is used to aid in the treatment of ulcers, ear infections, respiratory and cardiac disorders. 1 The seeds are characterized by acaricidal activity, 3 which revealed anti-carcinogenic effects, especially against breast cancer, potential phytotoxicity 4 and cancer chemopreventive. 5 Previous phytochemical investigations of this plant resulted in the isolation of coumarins, 2,6 cassanediterpenoids, 5,7 isoflavonoids, 8-10 isoflavolignans, 5 fatty acids 4 and lupane triterpenoids.…”

“…A cumarina (1,2-benzopiranona), formada por um anel aromático fundido em um anel lactona, possui grande potencial para utilização como herbicida (Oliveros-Bastidas et al, 2013), aromatizante (Oliveira et al, 2013), em perfumes, em cosméticos, anti-inflamatório (Leal et al, 2000), além de fins medicinais, como na prevenção e tratamento de edemas e câncer (Grötz et al, 2001;Mohler et al, 1994;Thornes et al, 1994).…”

“…Reporta-se na literatura que sua extração ocorre, normalmente, a partir do uso de solventes orgânicos, como etanol e metanol (Oliveros-bastidas et al, 2013;Thada et al, 2013). No entanto, a utilização de solventes orgânicos geram resíduos químicos e podem, inclusive, alterar as características do produto final devido às altas temperaturas empregadas durante os processos de extração e purificação.…”
