Popis:	A high-performance liquid chromatography method for the quantification of flavonoids from Macrothelypteris viridifrons (Tagawa) Ching, Thelypteridaceae, was developed. The analysis was performed on a C18 column with a gradient elution of methanol and water at a flow rate of 1 ml/min and a wavelength of 262 nm. All standard calibration curves exhibited good linearity (r2 > 0.9955) within the test ranges. The precision (intra-day and inter-day tests) revealed relative standard deviation values within the ranges of 0.54–2.03% and 0.84–2.38%, respectively. The recoveries were in the range of 97.51–100.19%. The relative standard deviation values for stability and repeatability were
