Headspace volatiles of marihuana and hashish: Gas chromatographic analysis of samples of different geographic origin

Extraction and analysis of different Cannabis samples by headspace solid‐phase microextraction combined with gas chromatography‐mass spectrometry

“…No direct correlation was observed between the content of these compounds and the geographical origin; genetic factors only were involved in the observed variations [12,13]. Furthermore, a poor repeatability in volatile composition was observed in samples originating from the same batch.…”

Grinding and Fractionation during Distillation Alter Hemp Essential Oil Profile and Its Antimicrobial Activity

“…The concentration of β -pinene was found to be dependent on location and harvest time and varied from 2.3 to 3.6% in the EO of cv. Fedora 17 [ 26 ], up to 9.2% in commercial hemp EOs [ 19 ], and was 2.2% in marijuana EO, [ 31 ].…”

“…CS (Carmagnola Selezionata) was 5–6% [ 17 ]. Myrcene in the drug-type hemp (marijuana) tissue was relatively low, (0.7–4.3%) in female flower buds [ 34 ], and it was 1% in the marijuana EO [ 31 ].…”

“…Limonene, monocyclic monoterpene, is found in all types of hemp, it is one of the signature compounds in marijuana headspace [ 33 ]. For example, limonene concentration in drug-type hemp varied between 0.03 and 1.53% [ 34 ], the sum of limonene and β -phellandrene was reported to be 1% of marijuana EO [ 31 ].…”

“…The concentration of caryophyllene oxide was reported to be 5.2–5.9% in the EO of cv. Carmagnola Selezionata [ 17 ], 0.5–9.5% in commercially available hemp EOs [ 19 ], and 7.4% in the EO of marijuana [ 31 ].…”
