Quantitative Determination of Δ9-THC, CBG, CBD, Their Acid Precursors and Five Other Neutral Cannabinoids by UHPLC-UV-MS.

Planta medica
Cannabinoids are a group of terpenophenolic compounds in the medicinal plant (Cannabaceae family). Cannabigerolic acid, Δ-tetrahydrocannabinolic acid A, cannabidiolic acid, Δ-tetrahydrocannabinol, cannabigerol, cannabidiol, cannabichromene, and tetr...

An alternative method to measure the diffusing capacity of the lung for carbon monoxide in infants.

Pediatric pulmonology
BACKGROUND: Lung diffusion assessed by the uptake of carbon monoxide (DL ) and alveolar volume (V ) by inert gas dilution are readily assessed in cooperative older subjects; however, obtaining these measurements in infants has been much more difficul...

Dual solid-phase and stir bar sorptive extraction combined with gas chromatography-mass spectrometry analysis provides a suitable tool for assaying limonene-derived mint aroma compounds in red wine.

Analytica chimica acta
A novel analytical method was developed for quantitative determination of eight limonene-derived monoterpenes responsible for the mint aroma in red wine. As these aromatic compounds are present at trace levels, a new dual extraction approach was prop...

Fa yi xue za zhi
OBJECTIVES: To establish a method for the analysis of methcathinone in urine by gas chromatography-mass spectrometry (GC-MS).

Adult fly age estimations using cuticular hydrocarbons and Artificial Neural Networks in forensically important Calliphoridae species.

Forensic science international
Blowflies (Diptera: Calliphoridae) are forensically important as they are known to be one of the first to colonise human remains. The larval stage is typically used to assist a forensic entomologists with adult flies rarely used as they are difficult...

The effects of Ficus carica on the activity of enzymes related to metabolic syndrome.

Journal of food and drug analysis
The present study aimed to investigate the effects of the various parts of Ficus carica L. (figs) on antioxidant, antidiabetic, and antiobesogenic effects in vitro. Fruit, leaves, and stembark of the F. carica plant were sequentially extracted using ...

Quantification of fatty acids in the muscle of Antarctic fish Trematomus bernacchii by gas chromatography-mass spectrometry: Optimization of the analytical methodology.

Chemosphere
This work presents data on the quantification of fatty acids (FAs, in terms of mass unit per tissue weight) in the muscle of Trematomus bernacchii, a key species in Antarctica, often used as bioindicator for contamination studies. Modifications in fa...

Stability of endogenous GHB in vitreous humor vs peripheral blood in dead bodies.

Forensic science international
For the first time, the stability of GHB was tested in post-mortem peripheral blood and vitreous humor samples, collected from 22 dead bodies at two different times: at the external body examination at the place of death and then during autopsy. An a...
