“…For this reason it is now being cultivated to reduce the overexploitation of the spontaneous forms [11]. Thymol, carvacrol, p-cymene, sabinene hydrate, and γ- terpinene were identified as major constituents of O. syriacum EO [8,12,13], known for their antibacterial and antifungal activities, antispasmodic and radical scavenging effects, acetylcholine esterase and lipid peroxidase inhibition, white blood cell macrophage stimulation, and cardiac depressant activity [14,15,16]. Altitude, region, time of harvest, and plant part influence the composition of O. syriacum EO [8,12,17,18,19,20].…”

Background: Origanum syriacum L. is an aromatic plant growing wild in Lebanon. This species is highly used in Lebanese traditional medicine and is a staple food in Lebanese gastronomy. Due to the over-harvesting, this species has become a cultivated crop rather than being collected from the wild. This study aims to evaluate the chemical polymorphism according to soil type. Methods: Plant samples were cultivated in different soil types including manure, potting mix, professional agriculture mixture, vegetable compost, nursery soils, and natural agricultural soil inoculated with arbuscular mycorrhizal fungi. After 16 weeks of culture, fresh shoot biomass was measured. Root colonization rate was evaluated and foliar biomasses were used for essential oil (EO) extraction. EO yield was calculated and the identification of the main chemical compounds of EO samples was performed by gas chromatography (GC) and gas chromatography–mass spectrometry (GC/MS). Results: Our findings revealed that the soil type affects the O. syriacum chemotype. Indeed, the EO samples could be divided into two groups: thymol chemotype group including manure and vegetable compost soils and non-sterilized non-inoculated EO samples, and the thymol/carvacrol chemotype including potting mix, professional agriculture mixture, nursery mixture, sterilized non-inoculated, non-sterilized inoculated, and sterilized inoculated EO samples. These results showed that manure and vegetable compost soils promoted thymol synthesis, whereas potting mix, professional agriculture mixture, and nursery mixture soils were thymol/carvacrol chemotype. Moreover, mycorrhizal inoculation increased carvacrol and reduced thymol productions in comparison to non-inoculated conditions. Additionally, mycorrhizal inoculation showed significant enhancements in mycorrhizal rates and shoot biomass production with respect to the non-sterilized soil. Conclusions: These variations confirm the influence of the edaphic conditions on the chemical components biosynthesis pathways of oregano plants. The results of this investigation could be used for determining optimal soil type, leading to a good quality herb production.

“…On the other hand, harvesting time effect on O. syriacum essential oil composition is variable. Four studies reported that the highest essential oil yields were obtained when O. syriacum was harvested during the summer [ 20 , 21 , 23 , 24 ]. For O. syriacum essential oil composition variation, both thymol and carvacrol were reported to be higher in summer during the flowering period in two studies [ 21 , 23 ].…”

“…Another study found that wild O. syriacum leaves produced a higher level of thymol and cultivated O. syriacum leaves produced a higher level of carvacrol in June after flowering [ 25 ]. Thymol level was observed to be increased in May in one study [ 20 ], while in two studies thymol levels were higher when O. syriacum was harvested in early spring before flowering and during winter and autumn, and the levels of carvacrol were higher when O. syriacum was harvested in spring and summer [ 8 , 24 ]. For γ-terpinene and p-cymene levels, two studies reported that they were higher when O. syriacum was harvested in spring between February and May [ 20 , 25 ], while one study reported that p-cymene and thymoquinone levels were higher after the flowering stage from January to July [ 23 ].…”

The interest in za’atar has increased in recent years due to its economic, cultural, and functional importance. The traditional za’atar mix made from dried Origanum syriacum is now a demanded product nationally and internationally. Air-drying at low temperatures can preserve za’atar quality traits better than other techniques such as oven-drying. The Palestinian za’atar market has the potential to develop and increase its value. However, it is facing many challenges. Another valuable product of za’atar is essential oil. Za’atar essential oil quantity and quality are affected by many factors including geographical location, cultivation, harvesting season, soil, extraction method, temperature, and others. These factors interact with za’atar and with each other; therefore, some factors are more effective than others and further research is needed to determine the optimum condition for producing and obtaining za’atar essential oil. Antimicrobial and antioxidant activities are the main functionalities of za’atar essential oil that are behind its medicinal importance. One hundred and twenty-one compounds have been identified in za’atar essential oil. The most common compounds are thymol, γ–terpinene, carvacrol, and α-pinene. The variation in the composition among za’atar essential oil samples results from the different conditions of the studies during za’atar growth as well as essential oil extraction.

“…Η μέγιστη συγκέντρωση τόσο του ελαίου, όσο και των φαινολικών συστατικών του (καρβακρόλη-θυμόλη) παρουσιάζεται κατά τους καλοκαιρινούς μήνες, ενώ το ποσοστό του π-κυμενίου αυξάνει το φθινόπωρο (Kokkini et al, 1997). Παρόμοια αποτελέσματα παρατηρήθηκαν και σε φυτά Origanum syriacum, όπου τόσο η συγκέντρωση σε έλαιο, όσο και το ποσοστό της καρβακρόλης, πήραν τις μέγιστες τιμές τους κατά τους καλοκαιρινούς μήνες (Soliman et al, 2007, Toncer et al, 2010.…”

“…Επιπλέον, οι Tucker & Maciarello (1994) αναφέρουν ότι η διάρκεια της ημέρας, η θερμοκρασία και η υδατική καταπόνηση επηρεάζουν τη σύσταση του αιθέριου ελαίου φυτών ρίγανης. Οι ετήσιες διακυμάνσεις των κυρίων συστατικών των αιθέριων ελαίων θα μπορούσαν να αποδοθούν στις διακυμάνσεις των κλιματικών παραμέτρων, με το ποσοστό της καρβακρόλης να παίρνει τις μέγιστες τιμές του κατά τους καλοκαιρινούς μήνες (Toncer et al, 2010;Soliman et al, 2007). Σε φυτά μέντας (Mentha piperita L.) παρατηρήθηκε ότι οι μικρές και ψυχρές νύχτες με πλήρη ένταση φωτός κατά την ημέρα επηρέασαν την εκατοστιαία (%) σύσταση των μονοτερπενίων (Burbott & Loomis, 1967).…”
