检查
水分 不得过17.0%（通则0832第四法）。
炮制
用时打碎。
贮藏
置干燥处，防潮。
鉴别
（1）本品粉末棕褐色。可见针状结晶及黄棕色块状物。 （2）取火柴杆浸于本品水浸液中，使轻微着色，待干燥后，再浸入盐酸中立即取出，置火焰附近烘烤，杆上即显深红色。 （3）取本品粉末0.5g，加乙醚30ml，超声处理10分钟，滤过，滤液蒸干，残渣加甲醇5ml使溶解，作为供试品溶液。另取儿茶素对照品、表儿茶素对照品，加甲醇制成每1ml各含0.2mg的混合溶液，作为对照品溶液。照薄层色谱法（通则0502）试验，吸取供试品溶液5μl、对照品溶液2μl，分别点于同一纤维素预制板上，以正丁醇-醋酸-水（3∶2∶1）为展开剂，展开，取出，晾干，喷以10%硫酸乙醇溶液，加热至斑点显色清晰。供试品色谱中，在与对照品色谱相应的位置上，显相同的红色斑点。
含量测定
照高效液相色谱法（通则0512）测定。 色谱条件与系统适用性试验 以十八烷基硅烷键合硅胶为填充剂；以0.04mol/L枸橼酸溶液-N，N-二甲基甲酰胺-四氢呋喃（45∶8∶2）为流动相；检测波长为280nm；柱温为35℃。理论板数按儿茶素峰计算应不低于3000。 对照品溶液的制备 取儿茶素对照品、表儿茶素对照品，精密称定，加甲醇-水（1∶1）混合溶液分别制成每1ml含儿茶素0.15mg、表儿茶素0.1mg的溶液，即得。 供试品溶液的制备 取本品细粉约20mg，精密称定，置50ml量瓶中，加甲醇-水（1∶1）混合溶液40ml，超声处理20分钟，并加甲醇-水（1∶1）混合溶液至刻度，摇匀，滤过，取续滤液，即得。 测定法 分别精密吸取上述两种对照品溶液与供试品溶液各5μl，注入液相色谱仪，测定，即得。 本品含儿茶素（C15H14O6）和表儿茶素（C15H14O6）的总量不得少于21.0%。 饮片
