The production of valuable bioactive compounds in the medicinal plant Glycyrrhiza glabra L. (G. glabra) would benefit from biotechnological approaches for cultivation and induction metabolite-producing hairy roots. Germination trials were tested to overcome seed dormancy, achieving high germination rates with sulfuric acid treatment. Hairy root cultures cotyledons using Rhizobium rhizogenes strain 1724 showed highest transformation efficiency. A fast-growing line, line S, was subsequently...
The variation of the essential-oil composition among ten wild populations Stachys lavandulifolia VAHL (Lamiaceae), collected from different geographical regions Iran, was assessed by GC-FID and GC/MS analyses, their intraspecific chemical variability determined. Altogether, 49 compounds were identified in oils, a relatively high contents found. major essential oils myrcene (0.0-26.2%), limonene (0.0-24.5%), germacrene D (4.2-19.3%), bicyclogermacrene (1.6-18.0%), δ-cadinene (6.5-16.0%),...
Essential oils of the air-dried aerial parts five populations Thymus migricus Klokov & Desj.-Shost. collected from northwest Iran were obtained by hydrodistillation with yield 1.1 - 3.3% (w/w). The essential analyzed a combination GC-FID and GC-MS techniques, to check for chemical variability. According populations, twenty-nine components, representing 97.3 99.3% total identified. Oxygenated monoterpenes main group constituents in all samples (65.2 78.5%). Thymol (46.6 72.5%),...
Abstract To ascertain whether there are chemical and genetic relationships among some Thymus species also to determine correlation between these two sets of data, the essential‐oil composition variability six populations including: T. daenensis Č elak. (two populations), fallax Fisch . & C.A. Mey ., fedtschenkoi Ronniger , migricus Klokov Des .‐ Shost vulgaris L. were analyzed by GC GC/MS, randomly amplified polymorphic DNA (RAPD). Thus, 27 individuals using 16 RAPD primers, which...
Pollen morphology of some species the genus Malus (Rosaceae) was investigated taxonomically. All are characteristic by tricolpate pollens. Exine sculpturing is variable but mostly striate. However, may differ in degree density ridges and their orientation. The exine patterns M. trilobata florentina very similar were characterized short branched ridges. These show clear differences from other species, which have pollen grains with long unbranched or slightly
In present work, the chemical composition of essential oils obtained from dried flowering aerial parts Teucrium hircanicum L. (Labiatae) originated ten wild populations in Iran was analyzed by a GC-FID and GC/MS system. The oil yields varied 0.04% to 0.1%. A total thirty-two compounds representing 67.6-97.7% were identified. found be rich sesquiterpene hydrocarpons (E)-α-bergamotene (17.5-86.9%) (E)-β-farnesene (0.5-21.4%). Of identified compounds, (36.1-89.7%) included greatest fraction all...
Linum album (Ky. ex Boiss.) is an important medicinal plant that produces compounds such as the well-known anticancer lignan podophyllotoxin and fatty acids. Despite its high value, it has not yet been studied in detail under agricultural conditions. This study was conducted to evaluate morphological, phenological, physiological responses of six L. accessions different levels water deficit treatments (100%, 75%, 50%, 25% available water) pot Based on results, some morphological...
Abstract Thymus migricus Klokov & Desj.-Shost. was collected at full flowering stage from Northwest of Iran. The essential oil the air-dried aerial parts obtained by hydrodistillation with a yield 1.8 % (w/w). analyzed combination GC and GC-MS. Twenty compounds were identified, representing about 99.2 total detected constituents. main constituents thymol (55.6 %), γ-terpinene (16.7 geraniol (4.6 p-cymene (4.0 limonene (2.6 %) E-Caryophyllene (1.9 α-Pinene (1.8 %).
