Objective To establish a quantitative analysis method for the determination of multi-components in Draconis Resina, and to provide a evidence for the scientific evaluation and effective quality control of Draconis Resina. Methods Phenomenex Kinetex C18 column (100 mm × 4.6 mm, 2.6 μm) was used with a mobile phase of acetonitrile-water gradient elution. The flow rate was 1.7 mL/min, the column temperature was 40 ℃, and the detection wavelengths were 280 and 325 nm. Results The linear ranges of resveratrol, 7,4′-dihydroxy flavone, loureirin A, loureirin B, and pterostilbene were 7.76—248.4 μg/mL (r = 0.999 9), 6.84—219 μg/mL (r = 1.000 0), 5.75—184 μg/mL (r = 1.000 0), 0.08—322.6 μg/mL (r = 1.000 0), and 23.71—758.6 μg/mL (r = 0.999 8), respectively. The average recoveries of the five components were 97.61%, 99.24%, 102.72%, 101.75%, and 102.65% with RSD values of 1.16%, 0.87%, 0.86%, 0.49%, and 1.10%. Conclusion The method is rapid, simple, and accurate, and could be used for the quality control of Draconis Resina.
