A Study On Chemical Composition Of Flavonids In Tamarix Leptostachys Bge.

This paper, based on fresh branches and leaves of Tamarix leptostachys Bge. of Xinjiang, explores the isolation and identification methods of flavone. By integrating the theories and methods of botany, plant chemistry.Studies the flavonoid chemistry composition, analyzes the construction. Withdraw and isolate flavone by ethyl acetate and silica gel chromatography. Analyzes the construction with the spectrum data by the silica gel chromatography and UV,MS,HPLC,NMR…etc. The results show: 90% of three times the volume of ethanol in solvent 60 degrees conditions extraction, filtration, with Tamarix leptostachys Bge. rough mention liquid compounds category; After mentioning the steaming liquid rough water, oil ethers, ethyl acetate to the complex after cleansing pillar, chloroform-methanol 30:1 gradient itself after crystallization from Tamarix leptostachys Bge. separate sample from one category of flavone compounds, identification equipment for the use of spectrum : Quercetin...
