“…The total lipid fraction yield of D. palmatum grown under NT was 1.24% (of dry plant weight; DW) and the fatty acid composition was characterized by high amounts of palmitic acid (27.9%), linolenic acids (14.6%), linoleic acid (14.1%) and oleic acid (11.3%) ( Table 2 ). Concerning the amount of fatty acids in other species of the Dracocephalum genus, the fatty acid composition of D. kotschyi oil is composed of a high amount of polyunsaturated fatty acids and contains linolenic acid (61.2%) as the predominant fatty acid followed by oleic (18.1%) and linoleic (13.5%) acids [ 22 ]. The amount of linolenic acid in D. moldavica oil was 59.4% [ 23 ].…”

The influence of climatic factors, e.g., low temperature, on the phytochemical composition and bioactivity of the arctic plant Dracocephalum palmatum Steph. ax Willd. (palmate dragonhead), a traditional food and medical herb of Northern Siberia, was investigated. D. palmatum seedlings were grown in a greenhouse experiment at normal (20 °C, NT) and low (1 °C, LT) temperature levels and five groups of components that were lipophilic and hydrophilic in nature were characterized. The analyses indicated that D. palmatum under NT demonstrates high content of photosynthetic pigments, specific fatty acid (FA) profile with domination of saturated FA (53.3%) and the essential oil with trans-pinocamphone as a main component (37.9%). Phenolic compounds were identified using a combination of high performance liquid chromatography with diode array detection and electrospray ionization mass-spectrometric detection (HPLC-DAD-ESI-MS) techniques, as well as free carbohydrates and water soluble polysaccharides. For the first time, it was established that the cold acclimation of D. palmatum seedlings resulted in various changes in physiological and biochemical parameters such as membrane permeability, photosynthetic potential, membrane fluidity, leaf surface secretory function, reactive oxygen species–antioxidant balance, osmoregulator content and cell wall polymers. In brief, results showed that the adaptive strategy of D. palmatum under LT was realized on the accumulation of membrane or surface components with more fluid properties (unsaturated FA and essential oils), antioxidants (phenolic compounds and enzymes), osmoprotectants (free sugars) and cell wall components (polysaccharides). In addition, the occurrence of unusual flavonoids including two new isomeric malonyl esters of eriodictyol-7-O-glucoside was found in LT samples. Data thus obtained allow improving our understanding of ecophysiological mechanisms of cold adaptation of arctic plants.

“…Its leaf extract has been reported to have antihyperlipidemic (Ebrahim Sajjadi et al 1998), immunomodulatory (Amirghofran et al 2000), antinociceptive (Golshani et al 2004) and cytotoxic (Jahaniani et al 2005) effects. Aerial parts of D. kotschyi plants are sources of valuable flavonoids and essential oils (Ebrahim Sajjadi et al 1998;Gohari et al 2003;Monsef-Esfahani et al 2007;Saeidnia et al 2007) and its seeds are rich in linolenic, oleic and linoleic acids (Goli et al 2013).…”

“…The assessment of conjugated dienes and trienes is a good method for determining the oxidative state of oils. K 270 and K 232 indices are referred to the presence of primary oxidation products such as hydroperoxides and secondary ones such as α‐diketones and α‐unsaturated ketones, respectively, in oil sample . Formation of conjugated dienes is also related to the presence of higher amount of polyunsaturated fatty acids while conjugated trienes may be pertained to dehydration of conjugated diene hydroperoxides .…”

“…The most effect was also observed by rosemary essential oil at 3000 ppm as TPC in both glass and PET was the highest compared to control at day 80. The quantity of free fatty acids (FFA), measured as acidity (%oleic acid), is a very important qualitative factor as high levels of free acidity would be associated with a decrease in the oil quality . The free fatty acid content in fresh pistachio oil was 0.35%.…”

In this study, the antioxidant capacity of rosemary (REO) and peppermint (PEO) essential oils along with butylated hydroxytoluene (BHT) is investigated on oxidative stability of pistachio oil packaged in glass and polyethylene terephthalate (PET). The essential oils (EOs) and their mixture are added at 1500 and 3000 ppm concentrations into the oil stored for 80 days at 60 °C under darkness. In order to evaluate the efficacy of antioxidants, peroxide value (PV), thiobarbituric acid, total phenolic compounds, oxidative stability index (OSI), conjugated dienes and trienes, free fatty acids (FFAs), and iodine value is measured at intervals of 20 days. The results show that natural antioxidants can reduce PV and FFA levels about five‐ and threefolds compared to control, respectively. The OSI in raw pistachio oil (16 h) reduces to 5 h, while in treated sample by REO the reduction is only to 13 h after storage. Generally, the results reveal that in all measured parameters, following order can be observed for antioxidant activity: 3000 ppm REO>3000 ppm PEO>100 ppm BHT >1500 ppm REO >1500 ppm mixed >1500 ppm PEO > control. Moreover, the findings show that glass container is better than PET to retard oxidation process. Practical Application: Pistachio oil is known as a functional and commercial oil that is susceptible to oxidation due to its high level of unsaturated fatty acids. In this work, rosemary and mint essential oils as natural antioxidant are applied for improving oxidation stability of pistachio oil. Antioxidant capacity of rosemary (REO) and peppermint (PEO) essential oils is investigated on oxidative stability of pistachio oil packaged in glass and polyethylene terephthalate (PET). The essential oils are added at 1500 and 3000 ppm concentrations into the oil stored for 80 days at 60 ºC under darkness. The results reveal that in all measured parameters, following order can be observed for antioxidant activity: 3000 ppm REO >3000 ppm PEO >100 ppm BHT >1500 ppm REO >1500 ppm mixed >1500 ppm PEO > control. The findings show that glass container is better than PET to retard oxidation process.
