STUDIES ON THE CONSTITUENTS OF RHIZOMES AND ROOTS OF PODOPHYLLUM VERSIPELLE HANCE

The resin (about 4.2% in yield) obtained from the dried rhizomes and roots of Podophyllum versipelle Hance had been subjected to chemical examination with the aid of liquid chromatography, and two crystalline compounds were isolated. One of them was identified as podophyllotoxin (yield about 15% of the resin), another one yielded only in small quantity (about 0.33% of the resin) was proved to be identical with dehydropodophyllotoxin. Keampferol, a flavonoid was also detected from the resin by means of the paper chromatography and the paper ionophoresis.
