The chemical composition and antioxidant activity of essential oils and MeOH extracts of stems, needles, and berries from Juniperus rigida were studied. The results indicated that the yield of essential oil from stems (2.5%) was higher than from needles (0.8%) and berries (1.0%). The gas chromatography/mass spectrometer (GC/MS) analysis indicated that 21, 17, and 14 compounds were identified from stems, needles, and berries essential oils, respectively. Caryophyllene, α-caryophyllene, and caryophyllene oxide were primary compounds in both stems and needles essential oils. However, α-pinene and β-myrcene mainly existed in berries essential oils and α-ionone only in needles essential oils. The high-performance liquid chromatography (HPLC) analysis indicated that the phenolic profiles of three parts exhibited significant differences. Needles extracts had the highest content of chlorogenic acid, catechin, podophyllotoxin, and amentoflavone, and for berries extracts, the content of those compounds was the lowest. Meanwhile, three in vitro methods (DPPH, ABTS, and FRAP) were used to evaluate antioxidant activity. Stems essential oil and needles extracts exhibited the powerful antioxidant activity than other parts. This is the first comprehensive study on the different parts of J. rigida. The results suggested that stems and needles of J. rigida are useful supplements for healthy products as new resources.

“…We found that the catechin content of Pinus eldarica bark is one and a half times higher than that of Pinus nigra (0.03% vs. 0.02%). Another study reported phenolic constituents in cones and berries of the same Turkish coniferous pine species [18]. While, the range of catechin was 0.3-3.6% in this study, pinus eldarica contained 0.005-0.03% catechin.…”

Background: The antioxidant components have been identified in some pine species. Antioxidant properties of proantocyanidins reduce free radicals induced by DNA fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. Objective: In this study, we analyzed different parts of Pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. Methods: Pine specimens were collected from four different geographic locations in Tehran. The HPLC method (UV detector, C 18 reverse phase column, 4.6 mm (25 cm, and water/ H 3 PO 4 / methanol/ acetonitril as eluant) were employed for evaluating total polyphenols. The wavelength for detection of polyphenolic compounds was 280 nm in this study. Results: The highest range of total polyphenols was detected in the bark of this pine, specially reported a considerable amount of tyrosol in Pinus eldarica. Tyrosol stimulated resistance to oxidative stress and also has anti aging effect. Conclusion: The high amount of total phenolic compounds in P. eldarica bark might be attractive for future research considering its health benefits.

“…The disagreement between the results is probably due to the application of inappropriate methodology for phenolics detection. Apart from Kilic et al, [20] to date, there has been no other study of the phenolic profile of J. excelsa species, making this study the first one to reveal the phenolic profile of needles.…”

“…The results presented in this study are not in agreement with the only and limited study of the qualitative phenolics profile of the seed cones extract of J. excelsa. [20] Specifically, Kilic et al [20] investigated 16 phenolics in J. excelsa seed cones collected in Turkey by using GC-MS. However, they did not detect p-hydroxybenzoic acid and matairesinol, while catechin was present in the 282fold reduced amount compared with the result in this study.…”

Leaves and cones of the genus Juniperus, regularly used as a spice, could be a candidate for new food preservative with significant nutraceutical qualities. The main goal of this study was to evaluate the bioactivity and chemical profiling of the Juniperus excelsa leaves and cones in order to support its usage as a health-promoting food additive. The content of 44 phenolics was determined using Liquid chromatography tandem-mass spectrometry (LS-MS/MS), with catechin and quercitrin being the most dominant, especially in leaves (234 and 142 mg/g of leaves dry weight, respectively). Gas chromatography-mass spectrometry (GC-MS) analysis showed a simple terpene composition both in leaves and in cones, with α-pinene (31 and 77%), cedrol (37 and 8%), and limonene (15 and 6%) as the most abundant compounds, respectively. J. excelsa showed a noteworthy antioxidant effect comparable with butylated hydroxyanisole (BHA), especially leaves extract towards HO • and lipid peroxidation (LP) inhibition, which is particularly important in food-quality maintenance. Essential oil of leaves showed significant anti-inflammatory activity by means of inhibition of eicosanoids production and considerable antimicrobial activity against the clinically relevant and/or foodborne illness-causing bacteria. Due to its considerable bioactivity and high content of phenolics with proven health benefits, usage of J. excelsa as a food additive with valuable nutraceutical properties should be supported.
