In the past few years, much more attention has been paid to the analysis of alkaloids in RST, including matrine, oxymatrine, and sophocarpine, due to their various pharmacological activities, which include ameliorating throat inflammation (Li et al, 2012;Yoo et al, 2014;Lee et al, 2015) and suppressing in vitro cancer cell proliferation (Chui et al, 2005;Liu et al, 2006) as well as hepatoprotective effects (Cho et al, 1986;Long et al, 2004;Chai et al, 2012).
