detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Molecular recognition on supramolecular systems (XXXV)

A novel β-cyclodextrin derivative 4 bearing a pyridinio group on the primary side was synthesized by the reaction of 2-aminopyridine with 6-β-cyclodextrin monoaldehyde 3, and its complexation stability constants with several aliphatic amino acids have been determined in phosphate buffer solution ( pH = 7.2, 0.1 mol L) at 25 by using spectrofluormetric titrations. The stoichiometry is 1 1 for th...

Study on Some Chemical Compounds on the Vase Life of Two Cultivars of Cut Roses

Rose (Rosa hybrida L.) is one of the mostly cultivated cut flowers in Iran and around the world. The study was carried out to increase the vase life and quality of cut rose ‘Grand Prix` and ‘Avallanche` by using various floral preservative solutions. Floral preservative solutions were AgNO3, 8-HQS, nano silver and distilled water. Treatments were compared with tap water as control. The experime...
