||The herbs of Dregea volubilis
||DMSO, Pyridine, Methanol, Ethanol, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day.

METHODS AND RESULTS:
The structures of dregeoside Ap1 (1), dregeoside Ao1 (2), Dregeoside Aa1 (3), dregeoside A11 (4), dregeoside C11 (5), dregeoside Ka1 (6), and dregeoside Ka1 (7) were deduced on the basis of chemical and spectral evidence as drevogenin A 3-O-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, drevogenin A 3-O-β-D-glucopyranosyl-(1→4)-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, drevogenin A 3-O-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, drevogenin A 3-O-β-D-glucopyranosyl-(1→4)-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, drevogenin C 3-O-β-D-glucopyranosyl-(1→4)-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, drebyssogenin K2 3-O-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, and drebyssogenin K2 3-O-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside, respectively.
Among them, 1 and 2 were active against Ehrlich carcinoma (solid type), and the latter was also active against melanoma B-16.
