Figure 2

Multiple reaction monitoring chromatograms of rutin and the internal standard. The retention times were 2.25 and 2.85 min for rutin and IS (emodin), respectively, using reverse-phase HPLC with a mobile phase consisting of 0.1% acetic acid/acetonitrile (20 : 80, v/v). (a) Chromatogram for rutin; (b) chromatogram for emodin; (c) chromatogram for both rutin and emodin.
