Abstract

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.

Key words: tea; PTPs; targets; inhibitory effect
