Figure 1: HPLC trace of the PC-SPESII extract. The major representative peaks of herbs in the formula are marked by their retention times. Baicalin represents one of markers listed in the PC-SPESII formula. The following HPLC conditions using a Discovery C18 analytical column (  cm) were used: 100% methanol mobile phase at a flow rate of 1.0 mL/min and UV absorbance detected at 280 nm. Retention times of purified PC-SPESII are shown directly on this tracing.
