“…Some studies reported that the tectoridin can be transformated to aglycone tectorigenin by human and rat intestinal flora [7,8], so it possess hepatoprotective [9]. Otherwise, tectoridin acts as a weak phytoestrogen and thyroid hormone-like agent by activating estrogen and thyroid hormone receptors [10]. Therefore, tectoridin has important and comprehensive development values and a sensitive analytical method for tectoridin is highly needed.…”
