Pine needles are comprisde of many chemical components .vunctions of these components were introduced briefly .methods of extraction and analysis ,which had been used by the researehers ,were reviewed. TCL was sdopted to analyze where availably components are,in ethanol extraction or inwater exation,studying the effects of factors like solvent dosage, extraction time, extraction times and extraction temperature on the production extraction of flavonoids from pine needle,. and A better method of extraction of flavonoids from pine needle found through orthogonal test by UV - spectrophotometry, they can provide a reference for the further development and utilization of pine needles ,Theoretical foundation of the reasonable procedure can be provided for the flavonoid production from pine needle in the factory and it is significant for the production. Keywords:Pine needles; TCL, Flavonoids; Extraction; UV - spectrophotometry 目 录 2.5.1 配制芦丁标准溶液和供试品溶液………………………………………8
