| TITLE： | Identification Study on Cryptotympana pustulata Ecdysis Based on 3D Depth of Field Synthesis Technology |
| 摘要： | 目的：建立蝉蜕药材的现场快速鉴别方法。方法：采用3D景深合成技术，从样品喙的长短、上唇的大小及明显程度、下唇突出的程度及其上横沟的颜色、足部主刺和侧刺的数量以及形态、腹部气门的明显程度、腹板数目、侧板的数目及形态、背板环数、尾器等方面对50批蝉蜕及其混淆品样品进行鉴别。结果：50批样品中，S1～S5、S26～S30、S36～S50为真品蝉蜕；S21～S25为真品蝉蜕增重后的混淆品；S31～S35为真品蝉蜕提取后的混淆品；S6～S20分别为焰螓蝉、山蝉、北京僚蝉蜕皮，均为混淆品。蝉蜕与其混淆品的主要鉴别特征为真品蝉蜕腹部腹面呈三角形，其余品种腹部腹面近平行；山蝉蜕皮气门明显，其余品种气门不明显；山蝉蜕皮尾器侧面观较其余品种尖锐；焰螓蝉蜕皮前足副刺和端刺呈锐角，北京僚蝉蜕皮前足副刺和端刺呈钝角。结论：该方法简便、可靠，可用于现场快速鉴别蝉蜕及其混淆品种。 |
| ABSTRACT： | OBJECTIVE：To establish the rapid field identification method of Cryptotympana pustulata ecdysis. METHODS ： 3D depth of field synthesis technology was used to identify 50 batches of C. pustulata ecdysis and its adulterants from the length of beak ，size and protrusion degree of upper labial base ，the protrusion degree of the lower labial base ecdysis and the color of its upper transverse groove ，the number and shape of main and lateral spines on the foot ，significance of abdominal valves ，the number of webs ，the number and shape of side plates ，the number of tergum rings ，terminaliae，etc. RESULTS ：Among 50 batches of samples ，S1-S5，S26-S30，S36-S50 were C. pustulata ecdysis；S21-S25 was adulterants of C. pustulata ecdysis after weight gain ；S31-S35 was adulterants of C. pustulata ecdysis after extraction ；S6-S20 were ecdysis from Tibicen flammatus ，C. flammatta，Lyristes pekinensis ，all of which were adulterants. The main distinguishing feature of C. pustulata ecdysis and its adulterants was that abdomen and ventral surface of C. pustulata ecdysis were triangular ，and the abdomen and ventral surface of other species was nearly parallel ；the valve of C. flammatta ecdysis was obvious ，but those of other varieties were not obvious ；the lateral appearance of terminaliae of C. flammatta ecdysis was sharper than those of other species ；there was an acute angle between the front foot accessory thorns and the end thorns of the T. flammatus ecdysis，and an obtuse angle between the front foot accessory thorns and the end thorns of the L. pekinensis ecdysis. CONCLUSIONS ：The method is simple ，reliable and suitable for rapid field identification of C. pustulata ecdysis and its adulterants. |
