蝉蜕为蝉科昆虫黑蚱Cryptotympana pustulataFabr.羽化时的蜕壳。性味甘寒,归肺、肝经,功效疏散风热、透疹止痒、明目透翳、祛风止痉。作为临床常用药,近年来其化学成分、炮制、制剂、药理作用、临床等方面的研究都取得了较深入的进展。本文综述如下。1 化学研究 蝉蜕主要含氨基酸类,其中游离氨基酸12种,包括天冬氨酸、苏氨酸、谷氨酸、丙氨酸、甘氨酸、胱氨酸、缬氨酸、异亮氨酸、亮氨酸、苯丙氨酸、赖氨酸、精氨酸; This is the clam shell of the insect Cicada Cryptotympana pustulata Fabr. The taste of cold, the lungs, the liver, the effect of evacuation wind and heat, rash itching itch, eyesight through phlegm, wind phlegm only phlegm. As a commonly used clinical drug, in recent years its chemical composition, processing, preparation, pharmacological effects, clinical and other aspects of research have made more in-depth progress. This article is summarized as follows. 1 Chemical research quinones mainly contain amino acids, including 12 free amino acids, including aspartic acid, threonine, glutamic acid, alanine, glycine, cystine, valine, isoleucine, and bright ammonia. Acid, phenylalanine, lysine, arginine;
