According to a study published by "Journal of separation science", Juglandis Mandshuricae Cortex is the bark of Juglans mandshurica Maxim. which is used as a folk medicine plant in China and India. A total of 113 compounds were characterized using an ultra-high performance liquid chromatography-quadrupole/orbitrap high-resolution mass spectrometry method. Seven flavonoids were simultaneously quantified in 15 min, including myricetin, myricetrin, taxifolin, kaempferol, quercetin, quercitrin, and naringenin. All calibration curves showed a good linear relationship with r > 0.9990 within test ranges. Intra- and inter-day relative standard deviations were less than 2.16%, while accuracy validation showed recovery between 95.6 and 101.3% with relative standard deviation values below 2.85%. The validated method was applied to determine the contents of seven flavones in Juglandis Mandshuricae Cortex from seven sources.
