Research On Chemistry Of Rhodiola Crenulata (Hook.f.et.Thoms).S.H.Fu

Objective : To investigate chemical constituent of butanol exaction of Rhodiola crenulata (Hook. f. et. Thoms). S. H. Fu from Yunnan ,meanwhile to explore the exaction method and Determination of the major effectiveness ingredients—Salidroside and Tyrosol in Rhodiola crenulata (Hook, f. et. Thoms). S. H. Fu.Details of the study: 1. chemical constituent of butanol exaction of Rhodiola crenulata (Hook. f. et. Thoms). S. H. Fu; 2. Extraction method of Salidroside and Tyrosol; 3. Study on the Determination of Salidroside and Tyrosol by high performance liquid chromatography. Methods : To exact and Separate major ingredients of butanol part in Rhodiola crenulata (Hook. f. et. Thoms) by some methods .which includes column chromatography, gel chromatography and so on, then to gain molecular structure of compound by Spectrum , chromatography, mass spectrometry (MS) and nuclear magnetic resonance (NMR), and study extraction and separation methods of Salidroside and Tyrosol with Orthogonal and Uniform Pilot design and Compared with different traditional exaction methods ;To determinate the content of Salidroside and Tyrosol by RP-HPLC, at that time, to build the Determination of Salidroside and Tyrosol by rapid high performance liquid chromatography .Results:5 compouds were gained from butanol exaction of Rhodiola crenulata (Hook, f. et. Thoms). S. H. Fu, which were respectively Renulatin ,...
