<i>Z</i>‐2‐(β<i>‐</i><scp>d</scp>‐glucopyranosyloxy)‐3‐phenylpropenoic acid, an α‐hydroxy acid from rooibos (<i><scp>A</scp>spalathus linearis</i>) with hypoglycemic activity

Abstract

This study describes for the first time that PPAG increases in vitro glucose uptake and improves glucose tolerance in an obese insulin-resistant rat model, suggesting that it has potential as a new class of antidiabetic therapeutics that would contribute to the antidiabetic effect of rooibos.
