The compounds were isolated and purified by HP20 macroporous adsorption resin, ODS, silica gel, and Sephadex LH-20 column chromatography, as well as semi-preparative HPLC chromatography from the 80% ethanol extract of the root of Angelica decursiva, and their structures were identified based on
OBJECTIVE
To investigate the chemical constituents from Angelica keiskei.
METHODS
The constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography, and preparative TLC. Their structures were identified on the basis of spectral data and physiochemical
In this study, an in vitro tyrosinase inhibition assay in combination with ultra performance liquid chromatography-orbitrap mass spectrometry (UPLC-orbitrap-MS) was developed for the rapid screening and identification of tyrosinase modulators from roots of Angelica keiskei. Of the 15
