            formic acid in a water-acetonitrile system was used. In   in this study, with results as shown in Figure 5. Salvinorin
            addition, six kinds of chromatographic columns were   A, salvinorin B, epicatechin, and orientin were used to
            examined, as shown in  Figure  4. The results showed   screen for the optimal spray voltage in the negative ion
            that Hypersil GOLD (Thermo) achieved the best peak   mode, while dihydrotanshinone I, cryptotanshinone
            separation and yielded the highest number of compounds–  (Cry), and tanshinone IIA were used for the positive ion
            totaling 1,436–as determined by SIEVE software extraction   mode. Based on the peak areas of these compounds, the
            in both positive and negative ion modes. Spray voltage,   optimal mass spectrometry parameters were determined
            capillary temperature, and auxiliary gas temperature   as follows: spray voltages of 1.5 kV (positive mode) and
            significantly affect the sensitivity and accuracy of mass   3 kV (negative mode), capillary temperature of 350°C, and
            spectrometry. Therefore, these parameters were optimized   auxiliary gas temperature of 400°C.
