However, the main compound obtained and eluted from silica gel with 50% MeOH showed no sporulation induction.
Chlorogenic acid (14.59 mg/100 g) and gallic acid (29.56 mg/100 g) were the main phenolic compounds obtained from potato peel at 180 °C.
The main compound was obtained by preparative TLC (10 × 10 cm) in n-BuOH H2O AcOH n-BuOH H2O AcOHll portion oforr-DS-3.
The main aim of this paper is to study the synthesis of neodymium III) complexes with alacac and methacroylacetophenone-based copolymers with styrene and N-vinylcarbazole and compared the luminescence properties of all compounds obtained.
Structural studies using a monomeric cyclic compound obtained by the telomerization of 1 permitted to assign main repeating cyclic units of poly(1) to a six-membered ring.
The extract obtained by hydrodistillation presented no artemisinin and the main compounds presented were camphor, β caryophyllene, borneol e 1,8-cineol.
Proteins, lignin, cellulose, hemicellulose, lignocelluloses and the hydroxyl, carboxyl, and carbonyl and phenol groups are the main compounds capable of forming bonds with metallic ions in the structure of biosorbents obtained from jatropha biomass (Kurniawan et al. 2006; Demirbas 2008).
The chromatogram obtained by gas chromatography coupled with mass spectrometry showed the main compounds with different profile for nonpolar substances from Cy extract may be attributed to the extraction method.
The results showed that ethanol is more suitable for the extraction process because the phenolic compounds of interest were obtained with a lower percentage of ethanol (1.5%), while 2% methanol was required to obtain compounds such as ferulic acid and gallocatechin (data not shown), the main compounds present in the crude extract.
Moreover, large amounts of pure fractions containing the main bioactive phenolic compounds were obtained by SFE, which makes this technique the most promising for purification of the crude extract.
