Chemical constituents of Coccoloba peltata Schott leaves and Their cytotoxic activities

Abstract: Chromatographic fractionation of CH2Cl2:MeOH (1:1) extract of Coccoloba peltata Schott cultivated in Egypt afforded four compounds, lupeol acetate (1), ent-13-epi-manoyl oxide (2), 5-methoxymethyl7,8-dimethyltocol (3), and α-tocopherol quinone (4). The planar structures of the isolated compounds were concluded based on HRESIMS and NMR spectroscopy. X-ray crystallography of 2 is reported Leia mais…

Thermochemical biomass conversion process in a small-scale fluidized bed reactor: fast pyrolysis of eucalyptus wood and gasification of sugarcane straw

Abstract: his paper presents the results of two process for thermochemical conversion of biomass, the fast pyrolysis of eucalyptus wood, and the gasification of sugarcane straw, both in a lab scale fluidized bed reactor. The bio-oil yield obtained from pyrolysis of eucalyptus wood was 64,4 wt%, water content of 31 Leia mais…

Sugarcene biorefinery: unlocking the potential of the pyrolytic process to convert waste biomasses into value-added products

Abstract: The sugarcane industry generates significant amounts of waste, such as bagasse (SCB) and sugarcane straw (SCS), which can be reused as raw materials to produce a wide range of renewable chemicals. This study, employing an approach that integrates kinetic studies and comprehensive product characterization, assessed the potential of pyrolysis Leia mais…
