Studies on the Constituents of the Herb of Panax ginseng C. A. MEYER. II. : On the Flavonoid Constituents

The flavonoid constituents of Panax ginseng C.A.MEYER were studied. A new natural flavonoid, named panasenoside (III), C27H30O16·H2O, mp 225-228° (decomp.), was isolated from this plant, together with kaempferol (I) and trifolin (II) (kaempferol-3-O-galactoside). The hydrolysis of III with diluted a...

Summary:The flavonoid constituents of Panax ginseng C.A.MEYER were studied. A new natural flavonoid, named panasenoside (III), C27H30O16·H2O, mp 225-228° (decomp.), was isolated from this plant, together with kaempferol (I) and trifolin (II) (kaempferol-3-O-galactoside). The hydrolysis of III with diluted acid produced one mo1e each of kaempferol, glucose and galactose. The position of the sugar binding was proved to be on 3, since complete methylation of III with diazomethane and subsequent hydrolysis afforded 4', 5, 7-tri-O-methylkaempferol. III was also partially hydrolysed with a glycosidase of Aspergillus oryzae var. microsporus TRR-18 ("Vernase"), and trifolin was obtained. The panasenoside formula is therefore kaempferol-3-O-glucogalactoside.
