Rapid Determination of Total Thujone in Absinthe Using ¹H NMR Spectroscopy

Table 1

Results of method validation for thujone.

Parameter		Result
Linear range (mg/L)		1–100
LOD (mg/L)		0.3a
LOQ (mg/L)		0.9a
Precision (%)b	Intraday	4.0^c; 5.8^d
	Interday	4.9^c; 6.7d

aLimit of detection (LOD) and quantification (LOQ) were determined as signals for which the signal-to-noise ratio (SNR) were 3 and 10 correspondingly.
bPrecisions are expressed as relative standard deviation (RSD; %): intraday (𝑛=5), interday (𝑛=8).
cStandard solution.
dAuthentic sample.
