aRRF ofα-terpineol to vanillin；bA CP-SIL 8CB column（0.53mm×30m，DF=1.0μm）was used；c Internal standard

Following the addition of 50μL of internal standard solution（=5μg vanillin）to each serially-diluted standard（50，25，10，5，1and 0.5μg·mL-1），the mixtures were directly injected into the gas chromatograph equipped with a FID under the conditions described in the Materials and Methods section.The result showed that when the CV%forα-terpineol recovery was set at 15%[20-21]，the lowest quantitatively-determinable concentration ofα-terpineol was 5μg·mL-1（Table 2）.
