摘要
Abstract
[Objective] The ethanol extract of Lithospermum erythrorhizon was obtained to study its UV Vis spectra property.[Method] The etha-nol extract was obtained by extraction with 95%ethanol and rotary evaporation.And the chemical compositions of extract were analyzed by using thin layer chromatography.The effect of concentration, acid and alkali, oxidizing agent, free radical, UV light, solvent, temperature and time etc.on the UV Vis spectra of the extract was qualitatively studied.[Result] Five main components were obtained by thin layer chromatography analysis and four characteristic absorption peaks were found by the UV Vis Spectrum analysis.The characteristic absorption peak of the extract had not been changed by concentration, temperature, time, UV irradiation, free radical, oxidizing agent and acid, but changed by alkali and metal ions.[ Conclusion] The study can provide a certain theoretical basis for application of L.erythrorhizon.关键词
