Dimethoxyl-2-phenylvinylquinoline with the yield of 59% was synthesized under the basic condition by Friedlnder condensation reaction of benzylacetone with 6-aminoveratraldehyde ~using EtONa as a catalyst.

A new compound 2,3,7,8-tetramethoxy-11H-inden[1,2-b]quinoline was synthesized by Friedlnder condensation reaction of 5,6-dimethoxy-1-indanone with 3,4-dimethoxy-6-aminobenzaldehyde which was obtained from veratraldehyde.

Veratryl alcohol was synthesized through the reduction of sodium borohydride from veratraldehyde with isopropanol as solvent, followed by solvent extraction and distillation under reduced pressure.

A microwave induced synthesis has been used as a teaching experiment for undergraduate students for four years.

Content Change of Polydatin and Resveratol in Processed Products and Crude Materials of Two Different Species of Veratrum

Objective To study the effect of Veratrum extract coadministration with Scrophularia extract on the enzyme activity of CYP3A1/2 in rat livers.

Determination of vetatramine in Veratrum nigrum by HPLC-ELSD;

Effects of Veratrum nigrum alkaloids on central catecholaminer-gic neurons of renal hypertensive rats;

To study the content variation of ginsenosides and alkaloids during combination of ginseng with veratrum nigrum,the ginsenosides and alkaloids in the decoction of ginseng with veratrum nigrum were analyzed and compared by high performance liquid chromatography-electrospray ionization-mass spec-trometry (HPLC-ESI-MS) and electrospray ionization-mass spectrometry (ESI-MS).
