Simultaneous Determination of Volatile Constituents from Acorus tatarinowii Schott in Rat Plasma by Gas Chromatography-Mass Spectrometry with Selective Ion Monitoring and Application in Pharmacokinetic Study

Table 1

Analytical parameters for GC-MS of plasma analytes assayed by the present method.

Analytes	Calibration curve^a	Correlation coefficient	LOD (ng/mL)	LOQ (ng/mL)
Methyl eugenol	𝑦=5.874𝑥+0.014	0.999	1.553	4.236
𝛽-Asarone	𝑦=6.469𝑥−0.027	0.997	1.802	4.872
𝛼-Asarone	𝑦=6.326𝑥−0.020	0.999	1.685	4.719

aIn the linear regression equation, 𝑥 is expressed as analytes concentration (𝜇g/mL) and 𝑦 is expressed as peak area of analytes/IS.
