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...

Dimethyl 2,6,8-trimethyl-1,2-dihydroquinoline-2,4-dicarboxylate

The title compound, C(16)H(19)NO(4), the hydrogenated ring adopts a twisted conformation. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular N-H⋯O hydrogen bonds, forming infinite double chains along [001].
