The processing of mate-herb generates a residue rich in chlorophyll that can be used as a source of natural dyes. The extraction and modification of chlorophyll are carried out in an ethanolic medium, generating metal compounds with different shades and compatible with being dispersed as pigments in paints.

Compound derived from piperine is catalyzed by non-carbenic complexes based on Ru that presents results based on the different electronic and steric contributions of the catalysts.

Lipases are seen as appropriate alternative sources for biodiesel production in terms of availability and cost. Here the Octave, a free computational software is used to optimize the experimental design in the synthesis of ethyl oleate catalyzed by a native lipase from
A. niger.

A series of 1,2,3-triazoles derived from glycerol were synthesized and had their effects evaluated against Colletrotricum gloesporioides.

This work describes the evaluation of the toxicity of mercury as a heavy metal during the first stages of expression in bean seeds
P. vulgaris L.

Representative identification of flavonoid from Chamaecrista duckeana.

The figure shows the scheme for obtaining biodiesel from sunflower oil through the transesterification reaction using a heterogeneous natural zeolite catalyst impregnated with K₂O and one of the main analyzes for the characterization of biodiesel.

This review aims to provide an overview of the discovery and the main synthetic efforts and industrial production of artemisinin and its derivatives.

The four purification procedures of agathisflavone from leaves of Poincianella pyramidalis were performed and compared.

Validation of DLLME method for benzodiazepines in plasma samples using LC-DAD was an unsuccessful. Nevertheless, critical aspects have never been addressed were evaluated, especially validation parameters involving DLLME, benzodiazepines and biological samples.

A fictitious case of intoxication was used so that Pharmacy students could perceive the direct relationship of the techniques studied in an Organic Chemistry course with the future field of work.

A study based on a quantitative, longitudinal, and sociological approach found that there are three distinct socioeconomic profiles among students who enter Unesp-Araraquara chemistry courses.

The first chemical equation published in Brazil, in 1846, in the original version followed by another version using modern symbols, and finally in the way it is written today.
