苦参根从外形看来很像一般树根,若無經驗者就很难确定,也难与其外形类似的中药区分。现在介紹一种簡便而迅速可靠的鑑別試驗方法,以供参考: 用1—2%的氫氧化鈉或氫氧化鉀水溶液滴于药材表面(新陈或碎片),若是苦参根就立即呈現橙紅色,漸变为血紅色,久置顏色不消失;但如把苦参根的皮除去后再用上法試驗則無此反应,这一特点可与大黄根,或其它含有类似大黄成份的中药材相区別。 The root of Sophora flavescens looks very much like an ordinary tree root. If it is inexperienced, it is difficult to determine, and it is difficult to distinguish traditional Chinese medicine with its appearance. A simple, rapid, and reliable identification test method is now introduced for reference: A 1-2% aqueous solution of sodium hydroxide or potassium hydroxide is dropped on the surface of the medicinal material (fresh or fragmented), and if it is a root, it immediately appears orange. Red, gradient to blood red, long stay color does not disappear; but if the skin of Sophora flavescens root removed after the test method without this reaction, this feature can be with rhubarb, or other rhubarb ingredients containing traditional Chinese medicine Material difference.
