GC-MS/SIM chromatograms: (a) rat blank plasma sample; (b) standard solutions of methyl eugenol (0.2 μg/mL), -asarone (0.2 μg/mL), -asarone (0.2 μg/mL), and IS (0.1 μg/mL); (c) rat blood sample after a single oral administration of volatile oil of Acorus tatarinowii Schott. Peak 1: methyl eugenol; Peak 2: IS; Peak 3: -asarone; Peak 4: -asarone.
