Phenolic Acids and Flavonoids in Hypericum Perforatum L. Hairy Roots
Investigations have been made to develop an efficient protocol for identification and quantification of phenolic acids and flavonoids in hairy roots (HR) of Hypericum perforatum L. HR were induced from root segments of in vitro grown seedlings from H. perforatum, after co-cultivation with Agrobacterium rhizogenes A4. Transgenic status of HR was confirmed by PCR analysis using rolB specific prim...

متن کاملEffects of drought stress on total phenolics, phenolic acids, polyamines and some organic acids in two important Iranian grapevine cultivars
This study was conducted to assess the induced-changes in the content of total phenolics and individual phenolic acids, total and individual polyamines and some organic acids in the leaves of two important Iranian grapevine cultivars under different durations of drought stress, and to determine their involvement in grapevine drought tolerance. For this purpose, ‘Yaghuti’ as a drought-toler...
متن کاملAntioxidant activities, total phenols and total Flavonoids assay of Origanurm vulgare, Teucrium polium and Thymus daensis
Introduction: Medicinal plants are important sources of antioxidants. Natural antioxidants increase the antioxidant capacity of the plasma and reduce the risk of certain diseases such as cancer, heart diseases and stroke. Synthetic antioxidants commonly used in processed foods have side effects and are toxic. Therefore, there is a need for more effective, less toxic and cost effective ant...
