| Abstract: | A new screening and analysis method that combines in vitro metabolism with high-performance liquid chromatography-mass spectrometry
(HPLC-MS) was developed for the screening and analysis of an antineoplastic compound, coniferyl ferulate, which is present
in the rhizome of Rhizoma Chuanxiong. Infrared (IR), ultraviolet visible spectroscopy (UV-Vis), nuclear magnetic resonance (NMR) and element analysis were used
to identify the molecular structure of coniferyl ferulate. The quantitative analysis of coniferyl ferulate in different extracts
of Rhizoma Chuanxiong was carried out, and the metabolism of coniferyl ferulate was investigated by in vitro incubation with rat liver homogenate.
The metabolite of coniferyl ferulate, ferulic acid ethyl ester, was identified by HPLC-MS, UV-Vis and IR. In addition, antineoplastic
activities of coniferyl ferulate and ferulic acid ethyl ester were detected by the MTT assay. The observed inhibition rate
of coniferyl ferulate on the activity of HeLa cells was over 80% at 5.4 ng μl−1. However, its metabolite, ferulic acid ethyl ester, showed no antineoplastic activity in vitro.
