“…Based on GC-FID analysis, α-pinene was the most abundant among the monoterpene and sesquiterpene-type components of the extracts. Humulene, β-caryophyllene, terpinen-4-ol, sabinene and β-myrcene were present in relatively large amounts as well [ 10 ]. The total terpene hydrocarbon content in the extracts ranged from 38.68 (locality Miľpoš, year 2012) to 79.33 mg/g DM (locality Hôrka, year 2014) ( Table 2 ).…”

“…Therefore, we cannot exclude a certain proportion of some of the essential oil components described in the literature for this activity. In a previous study were detected the components β-pinene, limonene and sabinene in the essential oil of berry samples from the studied localities, which could be involved in the anti/pro-oxidant effects [ 10 ]. The fact that the antioxidant activity of the J. oxycedrus extracts (31% for non-crushed berries and 81.27% for crushed berries) was comparable to the activity of the J. communis extracts, despite the lower contents of total phenolic compounds in J. oxycedrus (11.76 mg/g DM in non-crushed berries and 1.01 mg/g DM in crushed berries), in comparison to those in J. communis (19.63 mg/g DM in non-crushed berries and 10.76 mg/g DM in crushed berries).…”

“…It is spread globally and exhibits a wide range of ecological adaptations. A wide geographical distribution is the main reason for the remarkable variation in the morphological characteristics and chemical composition of the secondary metabolites [ 9 , 10 ].…”

In the present study, in vitro hydroxyl radical scavenging activities, total phenols and terpene contents in 70% ethanol extracts were evaluated. Samples of crushed (CB) and non-crushed ripe juniper berries (NCB) collected at five localities in North-East Slovakia during the years 2012–2014 were compared. Standard or modified methods for determining phytochemical and antioxidant activity were used together with a novel method for the evaluation of the results after the correction of the measured values per gram of dry matter (DM). Statistically significantly higher DM contents (average values for three years) were found in the CB extracts (ranging from 18.86 to 21.91 mg/mL) in comparison to those for NCB (ranging from 2.59 to 9.90 mg/mL). Depending on the localities and years, the hydroxyl radical scavenging activity ranged from 15.52 to 32.85% for NCB and from 65.59 to 88.12% for CB, respectively. The contents of total phenols ranged from 43.75 to 246.75 mg gallic acid equivalents (GAE)/L (NCB) and from 151.84 to 278.19 mg GAE/L (CB), respectively. However, the higher content of total phenols per gram of DM was found in the NCB extracts (8.49–42.23 mg GAE/g DM) and then in CB (6.87–18.77 GAE/g DM). The results obtained in this study showed a higher efficiency for extraction from juniper berries in 70% ethanol if the pericarp was disrupted in comparison to that achieved with the maceration of intact berries.

“…The characteristic composition of the essential oil obtained by steam distillation from the ripe, non-fermented berry cones of Juniperus communis L. is described on the monograph Iuniperi aetheroleum, which defines the following requirements: 20-50% of α-pinene, 1-35.5% of myrcene, < 20% of sabinene, 2-12% of limonene, 1-12% of β-pinene, < 7% of trans-(E)-caryophyllene, 0.5-10% of terpinen-4ol, < 2% of bornyl acetate and < 1% of α-phellandrene. Previous studies carried out on EOs extracted by hydrodistillation from juniper berries of diverse geographical origin, including Greece, Italy, Spain, Serbia, Kosovo, Algeria, Lithuania, Estonia, Macedonia and Slovakia, showed a noteworthy variation both on the qualitative and quantitative profile (Chatzopoulou and Katsiotis, 1993;Falasca et al, 2016;Fejér et al, 2018;Foudil-Cherif and Yassaa, 2012;Glišić et al, 2007;Hajdari et al, 2015;Lo[zbreve]ienė et al, 2010;Orav et al, 2010;Sela et al, 2011;Vichy et al, 2007). While α-pinene was consistently the major compound in most EOs (although presenting a wide variation of content, ranging from 13.4% to 77.4%), a higher variability was found regarding the other compounds present at higher contents.…”

“…8 requirements (Angioni et al, 2003;Chatzopoulou and Katsiotis, 1993;Falasca et al, 2016;Foudil-Cherif and Yassaa, 2012;Lo [zbreve]ienė et al, 2010;Matović et al, 2011;Orav et al, 2010;Vichy et al, 2007). This noteworthy variation among the qualitative and quantitative composition can be ascribed to several factors that are known to influence the chemical composition of plant EOs, such as environmental conditions (climate, soil composition, etc), harvesting period/maturation of the berries and extraction method, among others (Fejér et al, 2018). While several reports can be found in the literature regarding the analysis of the essential oil extracted from juniper berries using a Clevenger type apparatus, few information is found on the chemical composition of commercially available oils (Filipowicz et al, 2003;Höferl et al, 2014;Falasca et al, 2016) Additionally, there is a scarcity of data regarding the chemical composition of juniper EO obtained from wild berries grown in Portugal.…”

A B S T R A C TThis study aimed at investigating the chemical composition and in vitro antimicrobial activity of juniper (Juniperus communis L.) berries essential oils (EOs), including commercial samples as well as the oil hydrodistilled from berries grown in Portugal, for which few information is available in the literature. The analysis was performed by gas chromatography coupled to mass spectrometry detection (GC/MS) allowing the identification of a total of 97 compounds. The EOs showed different chemical profiles with only one being according to the European Pharmacopoeia 8 requirements. The laboratory-hydrodistilled EO was characterized by its high content in α-pinene (41.6%), followed by β-pinene (27.6%) and limonene (6.4%), commercial EO1 by α-pinene (31.1%), β-myrcene (16.3%) and sabinene (7.5%) and commercial EO2 by δ-cadinene (16.0%), α-pinene (12.2%) and sabinene (9.4%). The distinct chemical profiles were also evidenced by principal components analysis (PCA), with a clear separation of the evaluated EOs. One of the commercial samples, showed the presence of propachlor, a banned herbicide in the European Union. All the EOs showed relevant antimicrobial activity as they presented microbicidal activity against Candida albicans and at least six of the ten tested bacteria. Commercial EO2 showed a higher biological activity, as it was active against all tested microorganisms, which could be related to its higher content in sesquiterpenes, in particular those oxygenated. Overall, results support the use of Juniper communis L. berries EO as an antiseptic in traditional medicine and highlight its potential as a biopreservative that could be used in different industries.

Profiles of the volatile organic compound (VOC) content of essential oils (EOs) extracted from young and old Juniperus communis L. needles were generated via gas chromatography combined with mass spectrometry (GC‐MS) and flame ionization detection (GC‐FID) and subsequently processed using multivariate statistical methods. These were then used to differentiate the EOs according to needle age and geographical origin. From a total 49 of VOCs identified, statistically significant differences (p<0.05) between young‐ and old‐needle EOs were found for 21 VOCs. Most of the EOs from the young needles showed higher (p<0.05) contents of α‐ and β‐pinene and sesquiterpenes (β‐ and γ‐elemene, germacrene D and B, α‐muurolene, and δ‐cadinene) and their oxygenated derivatives (α‐ and τ‐cadinol), while most of the monoterpenes (α‐thujene, sabinene, terpinolene, β‐myrcene, β‐phellandrene, and p‐cymene) were present in higher quantities (p<0.05) in the EOs from the old needles. The volatiles germacrene D, α‐ and β‐pinene, α‐cadinol, and sabinene were identified via stepwise and canonical discriminant analysis as the most valuable for EO discrimination according to needle age and geographical origin. Recognition and prediction ability tests of the EOs achieved 100 % accuracy in EO classification according to the above mentioned criterion.
