| 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. |

[Hasubanan type alkaloids in Stephania hernandifolia].[Pubmed:20931849]
Zhongguo Zhong Yao Za Zhi. 2010 Aug;35(15):1973-7.
OBJECTIVE: To study the hasubanan type alkaloids in Stephania hernandifolia. METHOD: The dried herbs of S. hernandifolia. were extracted with 95% ethanol. After removal of the solvent, the residue was first partitioned between acid water and petroleum ether, then the aqueous layer was basified and extracted with chloroform to obtain crude alkaloids. Column chromatograghic methods with on silica gel, Rp-18, MCI CHP 20P, Sephadex LH-20 were applied for the isolation and purification of the crude alkaloid fraction. The structures were elucidated by their physicochemical properties and spectral data. RESULT: Nine hasubanan type alkaloids were obtained and identified as aknadinine(1), longanone(2), stephasunoline (3), N-methylstephuline(4), Epistephamiersine(5), prostephabyssine(6), aknadilactam(7), dihydroEpistephamiersine(8), hasubanonine(9). CONCLUSION: Compounds 2-8 were isolated from this plant for the first time.
