Simultaneous Quantitative Analysis of Mixtures of Ixeridium dentatum (Thunb.) Tzvelev, Plantago asiatica L. and Rumex crispus L. Ethanol Extracts

 Recently, consume for functional cosmetics containing natural products has been greatly increased. In order to develop it as a natural cosmetic material, we selected Ixeridium dentatum (Thunb.) Tzvelev, Plantago asiatica L. and Rumex crispus L. that have antioxidant and anti-inflammatory effects. In this study, simultaneous quantitative analysis of the isolated compounds and natural product complexes (Mix.) were validated using high performance liquid chromatography (HPLC). The isolated six compounds were shown in a large linearity with a correlation coefficient (R 2 ) of 0.99. The limit of detection (LOD) of chlorogenic acid, plantamajoside, acteoside, emodin chrysophanol and physcion were 0.36 μg/mL, 0.36 μg/mL, 0.37 μg/mL, 0.30 μg/mL, 0.22 μg/mL and 0.12 μg/mL, respectively. The limit of quantification (LOQ) of chlorogenic acid, plantamajoside, acteoside, emodin chrysophanol and physcion were 1.10 μg/mL, 1.08 μg/mL, 1.12 μg/mL, 0.99 μg/mL, 0.66 μg/mL and 0.35 μg/mL, respectively. Content analysis showed chlorogenic acid (0.19 ± 0.02%), plantamajoside (0.48 ± 0.01%), acteoside (0.65 ± 0.01%), emodin (1.15 ± 0.11%), chrysophanol (0.73 ± 0.01%) and physcion (0.69 ± 0.09%). Therefore, the results of this study may provide for basic data of standardization research natural cosmetic material development on the I. dentatum, P. asiatica and R. cripus.
