    Thymol (2-isopropyl-5-methylphenol), and carvacrol (5-isopropyl-2-methylphenol) are the main components of the essential oils of some Laminaceae,Verbenaceae and Ranunculaceae members such as oregano, thyme, savory, etc. The formation of thymol and carvacrol is thought to involve hydroxylation of γ-terpinene and p-cymene precursors. They are produced by the plant species as a chemical defense mechanism upon exposure to pathogens, pests, herbivores, or environmental stresses. Accordingly, the potent antimicrobial and fungi toxic properties of these compounds against various plant pathogens have been demonstrated. They have antibacterial, antifungal, insecticidal, and anti-oxidative properties which are the basis for the wide use of these compounds in the cosmetic, food, and pharmaceutical industries.

    Background
    Pergularia tomentosa L. has several traditional uses and biological activities which need to be more investigated.
    Objective
    In this study, some ecological and phytochemical properties of Pergularia tomentosa were assessed. The flavonoids and cardenolides in the aqueous extract of leaves were identified with LCMS techniques.
    Methods
    Some quantity characteristics of P. tomentosa were measured. Extraction was performed according to the traditional method (aqueous extract at room temperature). Metabolite profiling was conducted using untargeted liquid chromatography coupled to high resolution mass spectrometry (LCeESI-OrbitrapeMS). Data were analyzed by Xcalibur version 2.1.
    Results
    Results showed that length of roots, leaves and fruits and the height of aerial parts were 23-30 cm, 2.5-3.2 cm, 4.9- 5.4 cm and 40-58.00 cm, respectively. Physiography and canopy cover were two important variables on these properties. We also identified 19 natural products in aqueous extract, 15 phenolics and flavonoids and 4 cardenolides. Three flavonoids (8, 11 and 14) and one cardenolide (17) had been previously isolated in P. tomentosa and 3 cardenolides (5, 18 and 19) has been reported for the first time in this plant.
    Conclusion
    Results indicated that the leaves of P. tomentosa are a rich source of flavonoids and cardenolides. These findings suggest that leaves of this plant can be a good source of natural antioxidant and antitumor compounds. However, this plant needs special conservational efforts. Therefore, planting this plant under the canopy or along the borders of waterways can help in an appropriate habitat for its conservation and reclamation.

    Background
    Fenugreek (Trigonella foenum-graecum L.) is an important medicinal plant that is a source of diosgenin, trigonelline and other valuable components. Fenugreek seeds is used for its pharmaceutical and nutraceutical properties.
    Objective
    The aim of present study was to investigate the genetic diversity within and between different populations of Trigonella foenum-graecum using DNA markers and phytochemical characteristics.
    Methods
    The total genomic DNA was isolated from 12 populations of Trigonella foenum-graecum collected from different regions in Iran. After optimizing PCR, 10 ISSR and 10 SCoT primers were used to amplify the genomic DNA of all genotypes. To investigate genetic distance, cluster analysis based on Jaccard similarity coefficients and UPGMA algorithm calculated for the 12 genotypes. Also, the trigonelline content was determined between 2 populations which had the highest genetic distance.
    Results
    Analysis of banding patterns of 10 SCoT primers revealed 92 polymorphic bands with an average of 9.2 fragments per prime. A total of 79 bands were generated from 10 ISSR primers, out of which 55 (68.21%) were polymorphic bands. The average values of dissimilarities based on the SCoT and ISSR data were 0.60 and 0.44, respectively. Also, shoot trigonelline content was significantly different between genotypes with the highest genetic distance.
    Conclusion
    Our results revealed a high level of genetic variation among fenugreek populations. The findings also indicated that SCoT technique is more informative than ISSR technique for evaluation of genetic diversity and relationships among fenugreek populations. The genotypes with the highest genetic distance based on SCoT data, were noticeably different in respect of trigonelline content.
