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. |
||
About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Pyrrolizidine alkaloids from crotalaria lachnosema and crotalaria naragutensis
Phytochemistry (oxford): 1988:3289-3292
Crotalaria lachnosema, from Nigeria, was found to contain two pyrrolizidine alkaloids, dicrotaline and its acetyl derivative, the natural occurrence of which is reported for the first time. The major alkaloid in C. naragutensis was Nilgirine, together with integerrimine, usaramine and a new alkaloid, acetyl integerrimine.
