“…Moreover, the compound is not specific to the spruce tree, as trans-4-thujanol is present in many plant species and especially abundant in those of medicinal importance (e.g. Groendahl et al 2008;Novak et al 2000), and which are well known for their fungicidal properties. For instance, essential oil of marjoram contains trans-4-thujanol as one of the main components (Novak et al 2000), and the oil acts as a fungicide (Sharma et al 2011).…”

We assume that trans-4-thujanol may have an antifungal property, like some Norway spruce monoterpenes, which can inhibit growth of the blue stain fungus, Ceratocystis polonica (Siem) C. Moreau (Novak et al 2014).…”

Abstract& Key message Spruce trees emit significant amounts of trans-4-thujanol, but the amount of this compound in bark decreases with tree age. Trans-4-thujanol acts as an efficient repellent for the bark beetle Ips typographus. & Context The spruce bark beetle, Ips typographus, is an economically significant pest of Norway spruce (Picea abies) that preferentially infests and kills old trees. & Aims We looked for spruce volatiles that were perceivable by I. typographus and that differed as the host tree aged. & Methods Bark beetles were collected in the wild. Bark samples from spruce trees of different age were hydrodistilled. Gas chromatography-electroantennogram detection (GC-EAD) was used to identify which compounds induced beetle olfactory responses. These were identified by gas chromatography-mass spectrometry (GC-MS). Behavioural responses of bark beetles were tested using a Y-tube olfactometer. & Results Several EAD peaks were recorded, of which trans-4-thujanol was consistently active and could be identified chemically unequivocally. The antennae of I. typographus females responded to a lower dosage of the compound than males, but both sexes were repelled by it. The bark of 10-year-old spruce trees contained 3 times more trans-4-thujanol than that of 35-40-year-old trees, 27 times more than that of 70-to 80-year-old trees, and 200 times more than that of 120-year-old trees. & Conclusions Trans-4-thujanol is a bioactive compound in Norway spruce bark that varies in amount with tree age and affects spruce bark beetle behaviour under laboratory conditions. It is suggested that trans-4-thujanol might play a role in both spruce tree defence and tree choice by beetles.

“…In fact, these culture conditions activate this enzyme, favouring the biosynthesis of cis-sabinene hydrate. Indeed, this is an intensive and spic component of marjoram, whereas the trans-sabinene hydrate does not have any typical properties of marjoram (1).…”

“…Later investigations showed that some of the above main constituents were found in numerous EO samples of O. majorana. Novak et al (1) mentioned that the main compounds of marjoram EO were the epimeric monoterpene alcohols, trans-sabinene hydrate, cis-sabinene hydrate, and cis-sabinene hydrate acetate. In fact, according to Vera and Chane-Ming (2), the main components were terpinen-4-ol and cis-sabinene hydrate in EO of O. majorana originating from Island.…”

Culture conditions and salt effects on essential oil composition of sweet marjoram (Origanum majorana) from TunisiaO. majoranashoots were investigated for their essential oil (EO) composition. Two experiments were carried out; the first on hydroponic medium in a culture chamber and the second on inert sand in a greenhouse for 20 days. Plants were cultivated for 17 days in hydroponic medium supplemented with NaCl 100 mmol L-1. The results showed that theO. majoranahydroponic medium offered higher essential oil yield than that from the greenhouse. The latter increased significantly in yield (by 50 %) under saline constraint while it did not change in the culture chamber. Under greenhouse conditions and in the absence of salt treatment, the major constituents were terpinen-4-ol andtrans-sabinene hydrate. However, in the culture chamber, the major volatile components werecis-sabinene hydrate and terpinen-4-ol. In the presence of NaCl, new compounds appeared, such as eicosane, spathulenol, eugenol, and phenol. In addition, in the greenhouse, with or without salt, a very important change oftrans-sabinene hydrate concentration in EO occurred, whereas in the culture chamber change appeared incis-sabinene hydrate content.

“…Currently, it perfoms the important productions of the MAP and their derivatives, which gives it a significant place in the international market. Among these we distinguish the plant of oregano which is widely used in cosmetic, pharmaceutical and food industries thanks to the flavoring, antimicrobial and antioxidant properties [1][2][3].…”

Abstract. This study focuses on the valorization of extraction residues of medicinal plants which represent approximately 80% of the gross weight of the plant. In this context we proceeded to the transformation of "marc oregano" to a material adsorbent type activated carbon. The oregano marc, obtained after extraction of essential oils and organic compounds, has undergone a chemical activation using the phosphoric acid 85% (H 3 PO 4 ). It is well known as precursors of lignocellulosic activating agent, allows the development of a large porosity in the activated material. The activated product has subsequently underwent heat treatment in the temperature range from 200 to 350 • C. The optimum temperature for development was set at 300 • C. The results obtained showed that the adsorbent material O 300 has developed the interesting textural properties. It is an adsorbent material like activated carbon, which presents, according to the BET method, a specific surface of 1200 m 2 · g −1 (specific surface area of commercial activated carbon is of about 905 m 2 · g −1 ). The application of adsorbent material developed O 300 in microbial decontamination of urban waste water, has revealed its effectiveness and its important adsorptive properties against pathogens pollutants from wastewater.
