cytellin and liquiritigenin

To study the chemical constituents of the red heartwood of the stems and roots of Caragana changduensis.. The chemical constituents were isolated and purified by means of several column chromatographic techniques,and their structures were determined by spectroscopic methods.. Ten compounds were isolated and identified as kushenin( 1),( 6aR,11aR)-3-hydroxy-4,9-dimethoxy-pterocarpan( 2),(-)-4-methoxymaackiain( 3),(-)-homopterocarpin( 4),2,4-dimethoxybenzoic acid( 5),2-methoxy-4-ethoxybenzoic acid( 6),3-acetyl-oleanolic acid( 7),7-hydroxy-2,3-dimethylchromone( 8),liquiritigenin( 9),and β-sitosterol( 10).. Compounds 1,3,5,7,and 8 are obtained from this genus for the first time. All the compounds are obtained from this plant for the first time.

To study the chemical constituents of Heterosmilax yunianensis.. The compounds were isolated and repeatedly purified with chromatograph and the structures were elucidated by physico-chemical properties and spectral analysis.. Eight compounds were obtained and elucidated as beta-sitosterol (I), glycerol monopalmitate (II), daucosterol (IIl), hexacosanoic acid (IV), 5-hydroxymethyl furaldehyde (V), hergapen (VI), ursolic acid (VII), liquiritigenin (VIII).. They have been isolated from this plant for the first time, and IV - VIII are obtained from the plants of Heterosmilax for the first time.
