Abstract: Ethanol as solvent,triterpenoids is extracted in combination with ultrasound and determined by UV spectrum. The influence of extracting time ,liquid to solid ratio,ethanol concentration on the yield of triterpenoids,is evaluated by single factor test and orthogonal test. The results suggest that,the most optimum conditions for this extraction,are extracting time 30min,liquid to solid ratio 8:1,and anhydrous alcohol as solvent. On this optimum conditions,the content of triterpenoids is 5.61%(W/W).

Key words: Fructus ligustri lucidi, triterpenoids, ultrasonic extraction, orthogonal test, UV spectrum
