Chemical Characterization of Lignin and Lipophilic Fractions from Leaf Fibers of Curaua (Ananas erectifolius) [PDF]

Journal of Agricultural and Food Chemistry, 2007
The chemical composition of leaf fibers of curaua (Ananas erectifolius), an herbaceous plant native of Amazonia, was studied. Special attention was paid to the content and composition of lignin and lipophilic compounds. The analysis of lignin in the curaua fibers was performed in situ by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ...

Stone Matrix Asphalt (SMA) with Construction Waste and Curauá Fiber (Ananas erectifolius)

Research, Society and Development, 2020
The SMA mixtures are characterized by a high void ratio, which favors binder draindown. In order to avoid this effect, fibers are added to the mixture, which in this case came from Curauá da Amazônia (Ananas erectifolius). The final composition studied resulted in 75% coarse aggregate, 15% fine aggregate, 10% filler, 0.3% of the Curauá fiber residue ...

Tricin‐lignins: occurrence and quantitation of tricin in relation to phylogeny

The Plant Journal, Volume 88, Issue 6, Page 1046-1057, December 2016., 2016
Summary Tricin [5,7‐dihydroxy‐2‐(4‐hydroxy‐3,5‐dimethoxyphenyl)‐4H‐chromen‐4‐one], a flavone, was recently established as an authentic monomer in grass lignification that likely functions as a nucleation site. It is linked onto lignin as an aryl alkyl ether by radical coupling with monolignols or their acylated analogs.

EVALUATION OF COMPOSITE MATERIALS WITH FIBER OF CURAUÁ PINEAPLE (Ananas Erectifolius)

, 2015
In this paper was carried out a study on the behavior of composite materials with fiber of curaua (Ananas Erectifolius s.p. ) in matrix of epoxy resin, in different corrosive media such as oil, petroleum and water. The fiber at Amazonian origin presents a great potential, to relate good properties, low cost and low density. Molds were manufactured with
