| 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. |

Studies on the indole alkaloids of gelsem1um elegans (thailand): structure elucidation and proposal of biogenetic route
Tetrahedron, 1988 , 44 (16) :5075-5094.
Chemical investigation of the roots of collected in Thailand resulted in the isolation of the new indole alkaloids, 16-epi-voacarpine, 19-hydroxydihydrogelsevirine, and 19-(Z)-taberpsychine, along with eight known bases. Among them, the structure of “akuammidine” and koumidine were revised to have 19-(Z) ethylidene configuration. From the seeds of 14-hydroxygelsedine was obtained. Furthermore, three new alkaloids, Koumine N-oxide, gelsemine N-oxide, and 19-oxo-gelsenicine, were found from the leaves of . A new and plausible biogenetic route of gelsemium alkaloids is proposed.
