Its structure was determined as 3-methoxy-4-hydroxy-5-[ (8 S ) -3-methoxy-4- hydroxyphenylpropyl alcohol]-E-cinnamic alcohol-4-O-b-D-glucopyranoside by means of NMR and MS analysis, acid hydrolysis and optical data.展开更多
A new isoflavonoside, 7-hydroxy-4'-methoxy-isoflavonone-7-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside was isolated from roots of Bupleurum scorzonerifolium Willd., and named as saikoisoflavonoside A....A new isoflavonoside, 7-hydroxy-4'-methoxy-isoflavonone-7-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside was isolated from roots of Bupleurum scorzonerifolium Willd., and named as saikoisoflavonoside A.

The protoplasts of Red Thorowax ( Bupleurum scorzonerifolium) irradiated by ultraviolet light (UV) at an intensity of 260μW/cm2 for 0, 1,2 and 3 min respectively were fused with that of grapevine ( Vitia vinifera).

The regenerated 19 clones, every one derived from a single fused cell, were identified as hybrids by phenotype, isozyme, chromosome and 5S rDNA spacer region analysis. The results reveal that all of them are somatic hybrids. 11 hybrid calli includ-展开更多
