Abstract: Flavonoids from Sinaraundinaria nitida leaves werepreparedaccordingtoaL 9 (3 4 )orthogonaltestplan.The relationship between extractin g conditions and yield of flavonoids extracted from Sinaraundinaria nitida leaves was investigated.The result s showedthatthe processing conditions affectedthe yield,andthatthe e ffectof each condition decreased in the foll owing order:in proportion of extracting solvents and extracting time,with temperatureofextraction,andwith timeofpre -extractingimmersion.Boththesolvents proportionandextr acting time hada significanteffectonthe y ield(p<0.05),butthe other conditions didnotaffectthe yieldto a significant degree(p>0.05).
