摘 要:首次建议以抗病毒有效成分4(3H)-喹唑酮[4(3H-quinazolinone]作为大青叶、板蓝根类药材及制剂的质量控制指标。药理实验结果证明此成分有抗病毒活性及增强机体免疫力的活性,为此类药材和制剂的质量控制提供了更科学和可靠的依据。本文用高效液相色谱法对药材和制剂中的4(3H)-喹唑酮作了含量分析,取得满意结果。This paper suggests that the antiviral active constituent 4(3H)-quinazolinone maybe used as a quality control standard for the Chinese herbal drugs Daqingye(Folium strobilanthes)and Banlangen(Radix strobilanthes) as well as its preparations.4(3H)- quinazolinone was found for thefirst time from the above mentioned Chinese herbal drugs. Pharmacoiogical tests demonstrated that ithas antiviral and immuno regulating activities.This provides a reliable basis for the quality control ofDaqingye,Balangen and its preparations.Its con tentis determined by HPLC. The method showedgood linearity(r=0.9998,n= 5 ) in the range of 0.25~50μg/ml of 4(3H)-quinazolinone.Theaverage recovery was about 96~98%with RSD<1.69%(n=3).HPLC conditions:column : LiChrosorb RP 1 8(10μm);mobile phase:methanol一water(40:60);detection wavelength;230 nm。
