| 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. |

Rearranged clerodane diterpenoid from Tinospora crispa.[Pubmed:31242768]
Nat Prod Res. 2021 Feb;35(3):369-376.
A new rearranged clerodane diterpenoid, tinocrispide was isolated from the stems of Tinospora crispa along with thirteen known compounds including eight clerodane diterpenoids. Among the known compounds baenzigeride A, (6S, 9 R)-vomifoliol and Steponine are being reported for the first time from T. crispa. Their structures were elucidated by 1 D and 2 D NMR and confirmed by HRESIMS. The (13)C NMR data of borapetol A has been revised.
Quaternary isoquinoline alkaloids from Stephania cepharantha.[Pubmed:10726860]
Chem Pharm Bull (Tokyo). 2000 Mar;48(3):370-3.
From the quaternary alkaloidal fraction of the dried tubers of Stephania cepharantha, two new isoquinoline alkaloids, stecepharine and tetradehydroreticuline have been isolated along with the known compounds, magnoflorine, menisperine, Steponine, cyclanoline, oblongine, cis-N-methylcapaurine and 2'-N-methylisotetrandrine. cis-N-Methylcapaurine (=9-O-methylstecepharine) was isolated as a natural product for the first time. Their structures were determined on the basis of spectroscopic evidence.
