For the preparation of solutions, ultrapure water (type I water) was utilized alongside analytical-grade reagents, including sodium hydroxide (Neon, Suzano, SP, Brazil); ammonium hydroxide (Vetec, Duque de Caxias, RJ, Brazil); gelatin powder (Dinâmica, Indaiatuba, SP, Brazil); copper acetate (Êxodo, Sumaré, SP, Brazil); hydrochloric acid (Vetec, Duque de Caxias, RJ, Brazil); and sulfuric acid (Vetec, Duque de Caxias, RJ, Brazil) for the preparation of some solutions. Alcoholic solutions were prepared using ethanol (Dinâmica, Indaiatuba, SP, Brazil) combined with aluminum chloride (Dinâmica, Indaiatuba, SP, Brazil); ferric chloride (Proquímios, Rio de Janeiro, RJ, Brazil); quinine hydrochloride (Dinâmica, Indaiatuba, SP, Brazil); and vanillin (Dinâmica, Indaiatuba, SP, Brazil). Solvents such as hexane (Sigma-Aldrich, Darmstadt, Hesse, Germany); methyl alcohol (Vetec, Duque de Caxias, RJ, Brazil); and acetone (CRQ Química, Diadema, SP, Brazil) were also employed. Phytochemical screening utilized metallic magnesium shavings (Dinâmica, Indaiatuba, SP, Brazil); dried botanical material lavender and wormwood (Produtos Melvina, Goiânia, GO, Brazil); and oregano and sage (Produtos Gizele, Brasília, DF, Brazil), along with commercially procured bar soap.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
