Study on Chemical Constituents of Codonopsis thalictrifolia Wall. var. mollis( Chipp) L.T. Shen

Objective To study chemical constituents of Codonopsis thalictrifolia Wall. var. mollis( Chipp) L. T. Shen. Methods 95% ethanol aqueous extracts were separated and purified by various chromatographic techniques. The structures were elucidated on the basis of spectral analysis and TLC. Results Twelve compounds were obtained and their structures were identified as α-spinasterol( 1),β-amyrin acetate( 2),1,3-linolein-2-olein( 3),dibutyl terephthalate( 4),linoleic acid( 5),luteolin( 6),luteolin-7-O-β-D-glucopyranoside( 7),caffeic acid( 8),3-O-caffeoylquinic acid( 9),luteolin-7-O-β-D-gentiobioside( 10),trans-syringin( 11),lobetyolin( 12). Conclusion Compounds 1,3,4,7,8,9,10,11,12 were isolated from this plant for the first time.
