Barred Antshrike ( Thamnophilus doliatus )

16cm. Identification: The male is practically unmistakably recognized for the fully barred body and a black crest in the head. The female is ferruginous and has a crest and is barred in the head. It is currently the only antshrike which lives in really urban and disturbed areas. It is worth reminding that this bird has only recently conquered the urban environment. In the early 80s the first records of this antshrike in large cities were so unexpected that they yielded notes in scientific papers. Like other antshrikes it lives in couples, leaping and flying from branch to branch, usually through the short trees’ canopy in search for the small arthropods it feeds on. In the breeding seas...

Extraindo a clorofila

As clorofilas são os pigmentos que dão a cor verde às plantas elas não são solúveis em água e são mais instáveis em pH ácido, portanto podem ser extraídas usando um solvente orgânico como a acetona ou o metanol, e separadas através de cromatografia em papel. A separação é possível dada à diferença no número de grupos polares entre as clorofilas a e b: A fórmula molecular da clorofila a é C55H72N4O5Mg, e a da clorofila b C55H70N4O6Mg
