목적：우선상협황동류성분제취적최가공예。방법：채용자외분광광도법측정총황동적량，이상협총황동함량작위평개지표，사용색씨회류제취，채용 U（94）균균설계표설계시험，고찰제취용제농도、제취시간、료액비、과립도4충인소대총황동제취적영향。결과：상협중황동류성분적최가제취조건위：을순농도위60%，제취시간위8 h，료액비위1＇50，과립도위60목。결론：해제취공예조작간편합리，결과은정준학，중복성량호，구유가행성。
Objectiye:To optimize the extractive condition of flavonoids from Morus alba. Methods:UV were established to determine total flavonoids,U(94 )Uniform design form was selected as the experimentsˊschedule,the total flavonoids was used as evaluation indicator to and the extraction solvent concentration,extraction time,solid-liquid ratio and particle size was used as the 4 influencing factors. Results:The uniform design experiment show that ethanol concentration of 90% , the extration time of 8 hours,the solid-liquid ratio of 1' 50,and particle degree of 65 orders were the optimum extraction process. Conclusion:The method can quickly,accurately determine the optimum extraction technology of flavonoids from Morus alba.
