1. UPLC-Q-TOF-MS/MS Analysis Chromatographic analysis was carried out with a Waters Acquity UPLC-PDA system equipped with an analytical reverse phase C-18 column (2.1�100 mm, 1.7 ?m, Acquity BEH, Waters) with an absorbance range of 200 to 400 nm. The column temperature was maintained at 40 �C. 0.1 % formic acid in water (A) and 0.1% formic acid in acetonitrile (B) were used as the mobile phase;The gradient conditions were as follows: 0-2 min, 35 % B; 2-17 min, 35-98% B; 17-19 min, 98% B; 19-19.1 min
