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、HePTP 4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、HePTP 4个靶标均有很好的抑制效果,其抑制率均>92.0%,IC50均<5.5 mg/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 respectively. Based on these conclusions, tea soup of Pu-erh tea’s raw material sun-dried tea possessed different functional effects.
