大多数中药材来源于自然界的动植物。每种中药材都有其各自的颜色及色泽。颜色及色泽越鲜明纯正,往往说明其有效成分含量越高,质量和疗效越佳。如黄柏以颜色鲜黄者为优,白药以洁白者为上品,天冬以色黄白半透明为好,丹皮以断面粉白色、亮银星多者为佳,等等。药材的颜色及色泽不仅可作为鉴别药材品质的重要标志之一,也直接反映药材的保管、加工质量的优劣。鉴此,笔者拟对药材异常变色的原因作一归纳,冀以引起同道的注意。
Most Chinese herbal medicines originate from animals and plants in the natural world. Each Chinese herbal medicine has its own color and color. The brighter and purer the color and color, it often indicates that the higher the content of active ingredients, the better the quality and efficacy. For example, Phellodendron is preferred for those with bright yellow color, Whitener with white ones is the top grade, and Asparagus with yellow and white translucency is better, and Danpi is better with cross-section white and bright silver stars, and so on. The color and color of medicinal materials can not only be used as one of the important symbols to identify the quality of medicinal materials, but also directly reflect the quality of storage and processing of medicinal materials. In view of this, the author intends to sum up the reasons for the abnormal color change of medicinal herbs, in order to attract the same attention.
