Sir, please review test sheet for extraction of EO isolation method and analysis techniques - methodAndAnalysisExtraction20191225.tsv

There are extraction of first 20 articles of oil186.

PMC5307246 - No EO isolation method and analysis technique are mentioned.


PMC5426739 -  No EO isolation method and analysis technique are mentioned.

Column description is as follows.

  • PMCID - PubMed central id.

  • method - method used for EO isolation.

  • method_section - section containing method used for EO isolation.

  • analysis_1 - technique used for EO composition analysis.

  • analysis_2 - technique used for EO composition analysis.

  • analysis_section_1 - section containing technique used for EO composition analysis.

  • analysis_section_2 - section containing technique used for EO composition analysis.

Looks reasonable.
I don't think it's worth extracting the instrument typre yet, but that may
change
…

Sir, would you please give an example for making above change.

Sir, please review updated sheet for extraction of method for EO isolation and it's composition analysis techniques - methodAndAnalysisExtraction20191225.tsv.

There are extraction records from first 100 articles of oil186.

Notes:

There are articles which contains more than one extraction method names which have been put comma separated.

For example -

PMC5694587 	steam distillation, solvent extraction, soxhlet extraction, microwave-assisted hydrodistillation, dynamic headspace, static headspace, solvent flavor evaporation, solid-phase microextraction, and direct thermal desorption

PMC5622403 	steam or hydro-distillation

PMC5661929 	hydrodistillation, HS-SPME

PMC5723952 	hydroalcoholic extract, hydrodistillation

PMC5742650 	hydro-distillation, Microwave hydro-distillation

Sir, please review the extraction of EO isolation techniques and EO composition analysis - methodAndAnalysisExtraction20191225.tsv.

Suggest for making changes.

Sir, should I go for WIKIPEDIA lookup or WIKIDATA lookup for extraction method and analysis techniques?

ambarishK commented

Sir, EO isolation method - hydrodistillation/steam-distillation/microwave-ultrasonic/clevenger apparatus extraction etc - is explicitly mentioned into article sub-section.

Extracted value for EO composition analysis are abbreviation of technique names. As in gas chromatography coupled with mass spectrometry is extracted as GC-MS.

Most of articles mention composition analysis techniques as separate terms - gas chromatography separated of mass spectrometry - and that also into separate lines of corresponding sub-section.

Below is an example for it. Sub-section discusses gas chromatography coupled with mass-spectrometry but there is no explicit term as GC-MS.

PMC4391421

Gas chromatography-mass spectrometry. Samples were analyzed by gas chromatography using a HP6890 instrument coupled with a HP 5973 mass spectrometer. The gas chromatograph is equipped with a split-splitless injector and a Factor FourTM VF-35ms 5% fenil-methylpolysiloxane, 30 m, 0.25 mm, 0.25 μm film thickness capillary column. Gas chromatography conditions include a temperature range of 50 to 250°C at 40°C/min, with a solvent delay of 5 min. The injector was maintained at a temperature of 250°C. The inert gas was helium at a flow of 1.0 mL/min, and the injected volume in the splitless mode was 1 μL. The MS conditions were the following: ionization energy, 70 eV; quadrupole temperature, 100°C; scanning velocity, 1.6 scan/s; weight range, 40-500 amu.

GC-MS is not mentioned explicitly into EO composition analysis sub-section.

I have abbreviated them into single term - GC, GC-MS or GC-FID.

Sir, Please go through the added column for WIKIDATA query for EO isolation method and EO composition analysis techniques.

  • Should the representation for EO composition analysis techniques - GC-MS, GC/MS, Gas chromatography-mass spectrometry and gas-chromatography be made uniform as GC-MS and GC correspondingly?
ambarishK commented

There requires making the terms - GC-MS, GC/MS, Gas chromatography-mass spectrometry, gas-chromatography, hydrodistillation, hydro-distillation, steam-distillation, steam distillation etc uniform.

Apart, confirmation over extraction method - water extraction, clevenger apparatus extraction, steam-distillation and hydrodistillation as different extraction method is required to meet the extent of normalization.
