Methods A phenomenon luna C18 column was used with the mobile phase consisted of methanol-0.1 % phosphoric acid solution (82:18) at a flow rate of 1.0 mL/min and the detection wavelength was set at 254 nm. The column temperature was maintained at 30 ℃. Results The linear ranges of aloe-emodin, rhein, emodin, chrysophanol, and physcion were 1.057-67.67 mg/L (r =0.9999), 1.117-71.49 mg/L (r=0.9999), 1.047-67.02 mg/L (r=0.9999), 1.089-69.71 mg/L (r=0.9999),
