A reversed phase high-performance liquid chromatographic method was developed for quantifying E-ligustilide (1) and Z-ligustilide (3) in the roots of Angelica sinensis (Oliv.) Diels with confirmation using UV, atmospheric pressure chemical ionisation (APCI) MS and APCI-MS-MS techniques. Based on the
