Isolation of RNA from plants rich in secondary metabolites using commercial kits often results in contaminated preparations which are not suitable for downstream applications. Although many specific protocols appropriate for plants with a high content of phenolics, anthocyanins and polysaccharides have been developed, these are often expensive, time consuming and not applicable to different types...
Studies on new antibacterial therapeutics and strategies are currently being conducted in many microbiological, pharmaceutical and biochemical laboratories. The antibacterial activity of plant-derived compounds as well as silver and gold nanoparticles is the subject of this minireview. The application of photodynamic therapy is also discussed.
Extensive studies have been carried out to identify plant phenolics with insecticidal properties towards insects. The subject of the study were comparison of control and infested by Acyrthosiphon pisum (Harris) vegetative parts of pea plants. In the pea plants six flavonol aglycones were identified: quercetin, kaempferol+RCO-, kaempferol, tricin, apigenin+RCO-, and apigenin. In infested plants relatively...
Phenylpropanoids are a numerous group of the secondary metabolites. The pathway of phenolic biosynthesis is induced in plants under the treatment of various unfavorable factors. Phenylpropanoid compounds act twofold: they can be toxic for plant, inhibiting their growth and development, and, on the other side, they protect plants from stress effect. In the paper the most important phenolics, their...
Changes in total phenols and o-dihydroxyphenols concentration in seedlings of waxy and wax-less winter triticale hybrids under the grain aphid, Sitobion avenae F. and the bird cherry-oat aphid, Rhopalosiphum padi L. infestation were studied. Results revealed an inverse correlation between the concentration of the phenolics in aphid-infested triticale plants and the growth and development of the aphid...
