The analysis
was performed using Agilent 7890 A GC with an HP-5MS capillary column
(0.25 mm × 30 m × 0.25 μm) and a quadrupole mass spectrometer
Agilent 5975 C (Agilent, Santa Clara, CA, USA) as the detector. The
temperature conditions of the column were referenced by Yang et al.34 (link) The MS detection proceeded in electron impact
mode, and the ionization energy was 70 eV. The mass-scan range was
29–350 m/z at 2.88 scans/s.
Helium was the carrier gas at 1 mL/min.
Volatile compound identifications
were carried out by matching standard compounds and mass spectral
libraries (Wiley6 and NIST 98). A total of 17 standard compounds,
including 1-hexanol, 1-octen-3-ol, 2-ethylhexanol, benzaldehyde, benzoic
acid, benzyl acetate, benzyl alcohol, ethyl benzoate, geraniol, hexyl
acetate, linalool, nonanal, phenethyl acetate, phenylethyl alcohol,
prenyl acetate, terpineol, and β-pinene, and the internal standard
3-octanol was purchased from Sigma-Aldrich (Shanghai) Trading Co.,
Ltd. (Shanghai, China). The retention index values were derived from
alkane series (C7–C30) (Sigma, St. Louis,
MO, USA). All volatile compounds were quantified as 3-octanol equivalents,
and the results were expressed in microgram standard equivalents per
kilogram fresh weight (μg/kg FW).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
