“…Our findings agreed with previous investigations on the essential oil compositions from this species. For example, Talebi et al (2017) examined essential oil compositions of two populations (Polor and Dizin) of this species. In Polor samples, the main constituents of oil were: phytol (20.0%), caryophyllene oxide (8.3%) and β-caryophyllene (7.8%).…”

“…In this study, we examined the effect of altitude on the variations in essential oil compositions of three Nepeta species: N. sessilifolia, N. heliotropifolia, and N. fissa. Almost all previous studies on the essential oils of these species (Baser et al, 2000;Sajjadi & Khatamsaz, 2001: Jamzad et al, 2008Batooli & Safaei-Ghomi, 2012;Yarmohammadi et al, 2017;Talebi et al, 2017) were based on one mixed collective plant sample from one or two populations. By this way, we obtain a general picture of essential oil composition of these plants, and we lack the information about the chemical variability of its populations along the altitude gradient.…”

In the current study, the trichome density and the chemical variation of the hydrodistillated essential oils were determined along the altitudinal gradient in Nepeta sessilifolia, N. heliotropifolia, and N. fissa. The capitate glandular trichomes were predominant in all populations studied. Denser leaves indumentum was observed in high altitude populations of N. heliotropifolia, and in low altitude populations of N. sessilifolia and N. fissa. Moreover, the inter-population chemical polymorphism was detected. In the lower population of N. sessilifolia, spathulenol (14.2%) was the major compound of essential oils. This oil had great amount of oxygenated sesquiterpene (35.3%), while the oil of high altitude population had great amount of diterpenes, namely phytol (32.8%). In N. fissa, the main compound in lower population was β-caryophyllene (33.1%), whereas in the higher population it was caryophyllene oxide (21.5%). In N. heliotropifolia, 1,8-cineole (20.1%) was as the principal oil compound in low altitude population and β-caryophyllene (18.8%) in the high altitude population. We suggested that the amount of different types of monoterpenes decreases along the altitudinal gradient and the amount of oxygenated compounds increases with the elevation.

Phenolic content and antioxidant activity of Nepeta nuda subsp. albiflora Boiss. were reported in this study. The ethanol and water extracts of Nepeta nuda subsp. albiflora were prepared and used for biochemical analyses. Antioxidant capacities of the extracts were evaluated by three different in vitro bioanalytical methods including a reducing antioxidant method and two radical scavenging antioxidant methods. The water and ethanol extracts of the plant sample were found to have effective antioxidant potentials. Phenolic content of Nepeta nuda subsp. albiflora was determined by high performance liquid chromatography (HPLC). Rosmarinic acid (182.0±4.5 µg/g), apigenin (84.5±57.6 µg/g), and quercetin (44.5±62.9 µg/g) were identified as major compounds in the ethanol extract of the plant sample. This study has a potential scientific base for further studies about Nepeta nuda subsp. albiflora related to plant biochemistry and plant based pharmacological industry.

“…Some studies (Poverene et al 2002;Talebi et al 2017) have revealed that different populations of the same species show variations in life cycles, height, leaf shape and phytochemical characteristics under different ecological conditions. These conditions could be led to creation of ecotypes and chemotypes in response to ecological and environmental constraints of different habitats (Richards et al 2006).…”

Flax (Linum usitassimum L.) of family Linaceae is one of the most important crops, which has been widely used from ancient times. The aim of the study was to examine seed morphological characteristics and fatty acids differences among 13 populations of flax (11 from Iran, one from Turkey and one from USA). We studied six morphological variables of seeds in 50 replications. The methyl esters of seeds fatty acids were analyzed using GC. We detected that the flax seeds shape and color were stable among the populations, whereas ANOVA proved significant variations for all the quantitative seed morphological features. Moreover, we found the main fatty acids of the seed oil remained consistent over the ecological and geographical ranges of the populations, except for Khorasan and Turkey populations differed from the rest by their second main fatty acid. We registered that the amounts of main fatty acids differed among the populations and ANOVA test proved significant differences for most of the identified fatty acids. In addition, significant relationships were registered between some fatty acids. The populations were clustered in UPGMA tree and PCO plot into three distinct groups. CA joined plot and PCA biplot demonstrated that each group had specific type and amount of fatty acid. Therefore, we defined three chemotypes: petroselinic acid, linoleic and linolenic acids, and oleic acid. Although, studied ecological factors influenced some fatty acids amounts, populations from different phytogeographical regions clustered closely as chemotypes. This revealed that populations of each chemotype have been originated from the same diversity center, and some secondary diversity centers exist for flax in the world.
