分别讨论了连翘和车前子的化学鉴别方法。在连翘上，由于苯乙醇苷，即连翘苷和毛蕊花苷，与4-氨基安替比林发生显色反应，其特点是呈红色。此外，木脂素（arctigenin）与羟胺和氯化铁发生的显色反应的特点是呈现红紫色，木脂素（phillyrin）与硫酸发生的显色反应的特点是呈现红色。《日本药典十一》记载的连翘属的三个产地，由于木脂素的作用，其颜色反应不同，因而可以区分。在车前草中，车前草苷与4-氨基安替比林发生显色反应，也适用于薄层色谱法鉴别。
The methods for the chemical identification of Forsythiae Fructus and Plantaginis Herba are respectively discussed. On Forsythia Fructus, a color reaction with 4-aminoantipyrine due to phenylethanoid glycosides, namely, forsythiaside and acteoside, is distinctive by showing red. Moreover, a color reaction with hydroxyamine and ferric chloride due to lignan, arctigenin, is distinctive by showing reddish purple, and a color reaction with sulfuric acid due to lignan, phillyrin, is distinctive by showing red. The three origins of Forsythiae Fructus recorded in the Japanese Pharmacopeia XI, are distinguishable from each other by difference of color reactions due to lignans. On Plantaginis Herba, a color reaction with 4-aminoantipyrine due to plantamajoside is remarkable and its identification is also applicable by thin-layer chromatography.
