| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Epimeric (20R,20S)-Verazine Isolated from Veratrum maackii: Two-Dimensional NMR Studies and Total Assignment of 1H- and 13C-Resonances.[Pubmed:17226501]
Planta Med. 1992 Oct;58(5):449-53.
(13)C-NMR evidence shows that verazine [(25 S)-iminocholesta-5,22( N)-diene-3beta-ol] isolated from the Chinese plant VERATRUM MAACKII (Melanthiaceae) consists of a 20 R/20 S mixture of epimers. The determination of the configurations at the chiral epimeric center and of the conformation of the 17beta-side chain is based on the total assignment of the (13)C- and (1)H-NMR resonances. This goal was achieved by the extensive use of homo- and heteronuclear shift correlation and two-dimensional NOE spectroscopy methods at high magnetic field.
