中草药品种繁多,通常只是采用植物(动物)的某一部位入药(如根或块茎等),传统的形态、性状、显微和理化等鉴定方法存在一定局限,对于切片或加工产品更难以实现准确鉴定。有效鉴定技术方法缺失导致中药材市场品种混乱,伪品、替代品增多,已成为影响中药安全和行业发展的主要问题之一,例如,市售红景天药材只有40%属于中国药典规定的物种[1],关木通和广防己分别与不含马兜铃酸的木通和粉防己混用造成马兜铃酸肾病事件[2]。2015年2月,美国纽约
Traditional Chinese herbal medicines are usually used only for medicine (such as roots or tubers) in a certain part of the plant (animal). Traditional methods of identification such as morphology, traits, microscopic and physicochemical methods have some limitations. It is more difficult to accurately measure sliced or processed products Identification. The lack of effective identification techniques leads to confusion in the market of Chinese herbal medicines and the proliferation of counterfeit and substitute products. It has become one of the major problems that affect the safety and development of traditional Chinese medicines. For example, only 40% of the commercially available Rhodiola rosea belongs to the Chinese Pharmacopoeia [1], Guanmutong and GF have been with no aristolochic acid mixture of wood and powder caused by aristolochic acid nephropathy [2].
