Methods The UPLC-PDA chromatogram of Xiaoyaosan was compared with that of Angelica Sinensis Radix. The relative retention time of each peak and the Uhraviolet spectra providing by PDA were used in the analyses. Constituents were isola- ted from Angelica Sinensis Radix under the guidance of UPLC-PDA investigation. Structures of the isolates were elu- cidated by NMR techniques. Anti-depression effect was evaluated on glutamate-induced neurons. Results Five marker peaks of Xiaoyaosan fingerprint were belong to Angelica Sinensis Radix, and they were determined as conife- ryl ferulate（ I）, E-butylidenephthalide （ II）, ligustilide （III）, Z-butylidenephthalide （ IV ）, 14-Acetoxy-12-sene- cioyloxytetradeca-2E,8E,10E-trien-4,6-diyn-l-ol（V）. Compound V was isolated from the plants of Umbelliferae for the first time. Treatment with compound I, III, IV can protect PC12 and SH-SY5Y cell from glutamate-induced cytotoxicity. Antidepression bioactivity of compound I was first investigated. Conclusion UPLC-PDA guided iso-lation technique was confirmed to be a rapid and accurate method to identify the main active constituents from An- gelica Sinensis Radix contrubuting to Xiaoyaosan.展开更多
