OBJECTIVE
To establish a RRLC-UV method for simultaneous determination of oxypeucedanin hydrate, bergapten, oxypeucedanin, imperatorin, cnidilin and oxypeucedanin in Angelica dahurica var. formosana.
METHODS
The analysis was carried out on a Agilent Zorbax SB-C, (4.6 mm x 100 mm, 1.8 microm) column
Different extracts of Angelica dahuricae were available for whitening or treating vitiligo clinically. They showed inhibitory or activating effects on tyrosinase, a rate-limiting enzyme of melanogenesis. This study aimed to identify active compounds on tyrosinase in water extract of Angelica
