摘　　要：以抑制率和IC50为指标,分析测定了云南省不同地区晒青茶茶汤对PTP1B、SHP-1、SHP-2、HePTP4个PTPs靶标的抑制效果,以此来比较探讨普洱茶原料的保健功能性差异。结果表明,不同的晒青茶茶汤对PTPs靶标的抑制效果差异较大;73-11晒青茶茶汤对PTP1B、SHP-1、SHP-2、HePTP4个靶标均有很好的抑制效果,其抑制率均>92.0%,IC50均<5.5mg/mL。由此得出,不同普洱茶原料晒青茶茶汤的保健功效有所差异。Using inhibitory rate and IC50 as indexes,the inhibitory effects of sun-dried green tea soup from different areas of Yunnan on 4 targets of PTP1B,SHP-1,SHP-2,HePTP were investigated to compare the functional differences of Pu erh tea raw materals.Results indicated that the inhibitory effects of different sun-dried green tea were different significantly.Besides,tea cultivar 73-11 sample showed very good inhibitory effect on these four targets,its inhibitory rate and IC50 is >92.0% and <5.5 mg/mL respec...
