These results are in agreement with those obtained from a preliminary study toward the labeling accuracy of cannabidiol extracts preparations from products available on the US market. The over labeling of CBD products in the study was similar in magnitude to levels that triggered warning letters to 14 businesses in — from the US Food and Drug Administration suggesting that there is a continued need for federal and state regulatory agencies to take steps to ensure label accuracy of these consumer products.
Although CBD is a principal constituent of the examined cannabis oil extracts, the original plant is only capable of producing its acid form, cannabidiolic acid CBDA. Therefore, the determination of CBDA is important in order to evaluate the CBDA decarboxylation rate and effectiveness of the reaction during the extraction process [ 31 ].
This is quite problematic as the biological effects of the neutral and acidic forms are remarkably different [ 5 ]. Generally, expressing the CBD content as a sum of the acidic and neutral forms is conditioned by the analytical method applied. Concretely, it occurs when gas chromatography GC , one of the most commonly used analytical platforms for cannabinoid analysis, is used [ 31 ]. It involves the heating of the sample at high temperature in the injector prior to the chromatographic separation that leads inevitably to the decarboxylation of the cannabinoid acids.
Therefore, the analytical result is the sum of the acid and neutral forms. The GC method is still officially employed by the authorities for the determination of cannabinoids, but obviously is unsuitable. A few research groups continue to suggest that an accurate cannabinoid profile should be evaluated by determining the acid and neutral forms separately [ 12 , 31 ]. Results obtain in this study confirms this necessity.
On the contrary, there were a few samples with a significant amount of CBDA. In order to achieve full-spectrum in a hemp extract, the profile of bioactive compounds that a plant flower contains must be transferred into the extract itself without compromising any aspect of the profile.
In comparison with previous works available on cannabis oil [ 9 , 10 , 11 , 31 ] we employed a HRMS method that provided more complete information regarding the cannabinoids profile and amount in the oil composition. The obtained results clearly show that 12 out of 14 samples contained THC which is attention-grabbing because of its potential intoxicating activity. The THC content showed the considerable variability in the analysed samples, but was mainly at the levels describable as low 0.
This result highlights the importance of also specifying the amount of THC or any another intoxicating cannabinoid present in commercialised CBD oils.
Its detection is of great importance as it is not considered to be a natural cannabinoid but rather an artefact formed by THC oxidation during plant aging, by use of an inadequate extraction procedure or inappropriate storage conditions [ 32 ]. Therefore, its determination may assist in the evaluation of the quality of CBD oils with regards to the raw plant material used, extraction method applied and storage. In addition, CBN, though much less psychoactive than THC, express sedative effects [ 33 , 34 ] which is why its content should be indicated on the label along with THC.
The quantification of CBGA and CBG did not turn out to be imperative, but their presence could serve as a confirmation that the oil sample contains a natural, full spectrum cannabis extract. Among others data not shown it is important to highlight the persistent occurrence of CBDV in all analysed samples. Bearing in mind that this compound has expressed significant physiological activity [ 33 ] and that accompanies the CBD as its analogue, it should be included in any quality evaluation of full spectrum CBD oil preparations.
Besides, we noticed that when the hemp seed oil was used as matrix, the signal of CBDV augments notably, which means that maybe one portion of CBDV derives from hemp oil, not from flower extract [ 34 ]. Retrospective data analysis reveals the occurrence of CBDV: For the comparison, the CBD signal and fragmentation pattern is also presented.
There are at least two reasons to use the cannabinoid profile of Bedrolite oil extract as a reference point in the evaluation of CBD-rich hemp oils. Firstly, it can be considered as a full-spectrum extract that preserves the natural ratios of cannabinoids, any impurities that can compromise the experiments should be absent.
Secondly, many consumers tend to replace galenic oil preparations such Bedrolite oil extract with CBD-rich hemp oil extract, due to the fact that a medical prescription is required for the former. Our study revealed that Bedrolite oil extract contains 0. This is in agreement with theoretical percentage 0. These data are of great importance as they highlight the reduced concentration of all cannabinoids in Bedrolite oil extract compared to CBD hemp oil extract. The reasons for all the abovementioned variations between examined samples are numerous and multiple.
The final composition of CBD-rich hemp oil extracts depends on the chemotype and quality of the industrial hemp used, but it is also conditioned by the extraction method applied. Unfortunately, not all producers indicate the extraction method used.
Only four declared the use of supercritical CO 2 fluid extraction, which is shown to be the method of choice in that the low temperature and inert atmosphere results in higher CBD yields [ 18 , 19 ]. However, the main drawback of this technology is its high cost, and it is reasonable to assume that solvent extraction is also used for the inexpensive industrial processing.
However, it is questionable if this is a correct choice for a product for human consumption because residual solvents typically hexane, ethanol, isopropyl alcohol, toluene, benzene, xylene and acetone may contaminate the final product [ 32 ].
Without having complete information on the methods of CBD oils preparation, we investigated the occurrence of the most frequently used extraction solvents as solvent residues. Our analysis revealed the sporadic incidence of acetone Table 2 , ketones section that is more probably present as a lipid oxidation product rather than as a true residual solvent. Nevertheless, the presence of some volatile compounds that might be considered as problematic impurities from solvents residues was detected Table 2 , miscellaneous section.
Standard deviatio ; n. Terpenes and cannabinoids share biosynthetic pathways and, in fact, cannabinoids are terpenophenolic compounds. In Cannabis plants, terpenes are secreted and stored together with cannabinoids in glandular trichomes. Complete data concerning the terpenes profile are summarized and reported in Table 2.
Overall, up to volatile compounds composed the volatile fingerprint, including 48 terpenes that are further divided into classes as presented in Figure 2. Apparently, these formulations were obtained by an extraction process able to preserve naturally occurring terpenes profile from initial C annabis sativa plants, as their terpene profile is in accordance with those already published in literature [ 12 , 21 , 22 , 23 , 24 , 35 ].
The dominance of those two sesquiterpenes over the other terpenes detected in this preparation may indicate the geographic provenience of the starting Cannabis sativa material, and as a matter of fact, the producer specified the mountain region where the plant was cultivated.
Nevertheless, qualitative and quantitative differences observed in the chemical profiles of terpene fractions are conditioned by many factors such as: Those compounds correspond to secondary photooxidation products of the initial terpenes. In the presence of light and singlet oxygen, terpenes are also known to undergo photooxidation leading to the formation of allylic hydroperoxides [ 35 ].
Its presence is most likely to be due to the preparation method and could also be considered indicative of potential adulteration. On the another hand, the detection of aldehydes and ketones suggests the initiation of lipid peroxidation of polyunsaturated fatty acids PUFA in the oils used as a matrix, as demonstrated in our previous work concerning the observed trends of these compounds during storage of macerated Cannabis -derived oils [ 12 ].
It is well documented that peroxidation of PUFA leads to the formation of a well-defined series of aldehydes and ketones such as nonenal, hexanal and pentanal, 2-heptenal, especially during storage. The rate of formation of lipid oxidation products depends strictly on several factors, among which the most important are the preparation method temperature, fatty acid composition of the oil in which Cannabis extract was dissolved and the storage conditions storage temperature as recently demonstrated in a study [ 12 ].
These parameters are crucial to define the ultimate characteristics of the final products as evidenced also by the color of the samples Figure 3.
Other volatile decomposition compounds frequently encountered include 2-hexenal, 2-octenal, 2,4-nonadienal, 4,5-dihydroxydecenal [ 37 ], some of which also appeared to be present in some of our samples.
For the CBD oils analyzed in this study, tree different oil typologies were used: This preparation was the only one prepared in MCT oil, which means that this kind of matrix is less susceptible to oxidative degradation than the olive or hemp seed oils declared as matrices for other preparations enrolled herein. As far as olive oil is concerned, is often used by producers as it has a strong nutritional potential, being rich in the polyunsaturated fatty acids.
Moreover, FU oil pharmaceutical grade olive oil is used for the preparation of CBD galenic formulations [ 9 , 12 , 29 ] as it was performed for Bedrolite oil extract. Therefore, any cannabinoids detected actually represent hemp seed oil contaminants. Their concentration is influenced by the hemp variety and by the seed cleaning process. Although the cannabinoid concentration in hemp seed oils is usually extremely low, it must be determined before oil commercialization [ 39 ].

I see hemp oil advertised in soap, lotions , etc. Is all of that the same as CBD oil? Although CBD can be derived from hemp and neither oils have psychoactive effects like THC waxes and shatters at dispensaries, CBD and hemp oils are made from different parts of the plant and have different purposes.
CBD is a compound found in hemp flowers, so extractors try to pull as much of it from the plant matter as they can and then purify it further. You have successfully signed up for your selected newsletter s - please keep an eye on your mailbox, we're movin' in!
