HPLC conditions: chromatographic column was SB-C18 column (4.6 × 250 mm, 5 μm) and the column temperature was maintained at 30℃. The wavelength of ultraviolet detector were 280 nm and 320 nm, and the gradient elution with a flow rate at 0.8 mL/min was performed by mobile phase A (2% acetic acid in deionized water) and solvent B (methanol; 0–10 min, 5–30%; 10–35 min, 30–50%; 35–40 min, 50–60%; 40–45 min, 60–70%; 45–50 min, 70–5%; 50–55 min, 5%).

with minor modification, using an Agilent 7890 gas chromatograph (Agilent Technologies, Santa Clara, CA), equipped with an Agilent 5975C series mass spectrometer. The volatile compounds were separated using a DBWax (30 m × 0.25 mm i.d. × 0.25 μm; Agilent Technologies) fused silica capillary column. Helium was used as the carrier gas and it was circulated at a rate of 1 mL/min in constant flow mode. The oven temperature was held at 35 ℃ for 2 min, ramped at a rate of 2 ℃/min up to 45 ℃, then ramped to 130 ℃ at the rate of 5 ℃/min, and finally ramped to 225 ℃ at a rate of 10 ℃/min for 5 min.
