The oil was extracted from the plant leaves by water distillation using Clevenger type equipment (Hermex Glassware -Brazil). After extraction, it was stored in dark flasks in a refrigerator at 5ºC. The chemical properties were identified by gas chromatography using a model 7890 gas chromatograph (Agilent, USA) coupled to a model 5975 linear quadrupole type mass spectrophotometer (Agilent, USA). The oil components were identified based on the NIST11 mass spectra data (Agilent, USA) and on the Automated Mass Spectral Deconvolution Mass and Identification System (Agilent -USA). The concentration of the compounds was expressed as a percentage of the normalized peak area (each separated substance appeared as a peak on the chromatogram). The index adopted for quality was above 70%.
Nist11 mass spectra data
Manufactured by Agilent Technologies
Sourced in United States
NIST11 mass spectra data is a comprehensive library of mass spectra data provided by the National Institute of Standards and Technology (NIST). It is designed for use in the identification and characterization of chemical compounds. The NIST11 data includes mass spectra for a wide range of organic and inorganic compounds, along with associated metadata such as compound names, molecular formulas, and CAS registry numbers.

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.
