摘　　要：目的对蜂斗菜Petasites japonicus（Sieb.Et Zucc.）Maxim.进行显微鉴别和总黄酮含量测定。方法显微鉴别采用形态学和组织学鉴别方法,总黄酮含量测定采用分光光度法。结果蜂斗菜根茎中维管束为双韧型,根茎和根中具有分泌道;粉末中可见不定式气孔和非腺毛。蜂斗菜总黄酮含量为1.5-2.2%。结论上述显微特征及总黄酮含量测定可用于蜂斗菜药材的质量鉴定。Objective To establish a method of microscope identification and to determine total flavonoids content of Petasites japonicus（Sieb. Et Zucc.） Maxim.. Methods Morphological and histological methods be used for microscope identification, Spectrophotometry be used for determination of total flavonoids content. Result The bicollateral bundles exist in rhizome, the secretory canals exist in rhizome and stem of P. japonicus. Anomocytic type stomas and non-glandular hairs are visible in powder. The content of total flavonoids was 1.5 - 2.2%. Conclusion The microscopic character and the determination method of total flavonoids content can be used for the quality determination of P. japonicus.
