本調查以逢機取樣方式蒐購台北市地區中藥店市售之蒲公英檢體計25件,由性狀特徵及組職鑑別其基原,並採集台灣蒲公英、西洋蒲公英、兔兒菜、刀傷草、紫背草、蕒苣菜、黃鵪菜等藥材對照鑑定。市售蒲公英檢體中,經確認14件為兔兒菜(Lactuca chinensis Makino),8件為刀傷草(Ixeris laevigata (BI.) Sch.-Bip. ex Max.),1件為台灣蒲公英(Taraxacum formosanum Kitamura)摻有兔兒菜,1件為兔兒菜摻有紫背草(Emilia sonchifolia (L.) DC.),1件為半枝蓮(Scutellaria rivularis Benth.)。目前台灣藥材市場上以兔兒菜充當蒲公英使用佔較大部分,此外並有以刀傷草充用之。
