Preliminary Study On Chemical Composition Of Dracocephalum Heterophyllum Benth

Dracocephalum heterophyllum Benth. is the labiatae. With clearing heat and detoxication expectorant, alleviates shortness of breath, such as blood pressure-lowering effect, for the treatment of chronic bronchitis, bronchitis, hypertension and other diseases.The main thesis of this work are:1. Dracocephalum heterophyllum Benth. of flavonoids in the extraction process and research. Results: The content of total flavonoids 27.4110 mg/g; methanol concentration 70%,solid-liquid ratio1:40, extraction temperature70℃and extracting duration 2.5h.2.Using atomic absorption spectrometry Dracocephalum heterophyllum Benth. determination of inorganic elements in the content. The results showed that: The plant differences in the Ca, Fe, Mg, and other inorganic elements with higher levels.3. By steam distillation from Dracocephalum heterophyllum Benth. in the whole plant extract essential oil. Using gas chromatography - mass spectrometry to its volatile oil for chemical composition analysis. Identified a total of 30 components, mainly to alcohol, alkane and ketones.4.Its chemical composition of the extraction, isolation and identification of areas of the preliminary study, we isolated eight kinds of compounds from Dracocephalum heterophyllum Benth. they areⅠrutoside,Ⅱquercetin,Ⅲkaempferol,Ⅳapigenin,Ⅴluteolin,Ⅵluteolin-7-O-β-D-glucoside,Ⅶnaringin andⅧ:β-daucosterol. OnceⅣ,Ⅴ,Ⅵ,Ⅶ,Ⅷfor the first time from this plant isolated. More work for the future of Xinjiang Dracocephalum heterophyllum Benth.depth research and laid the foundation for the use of resources.
