| 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. |

Cytotoxic steroids of Gelsemium sempervirens.[Pubmed:3655795]
J Nat Prod. 1987 Mar-Apr;50(2):195-8.
A new pregnane derivative, 12 beta-hydroxy-5 alpha-pregn-16-ene-3,20-dione, along with the known derivative 12 beta-hydroxy-pregna-4,16-diene-3,20-dione have been isolated from a MeOH extract of the stem of Gelsemium sempervirens and found to be the principal cytotoxic entities. The 13C-nmr spectra of both compounds were assigned by comparison with other pregnane analogs thereby allowing confirmation of the stereochemistry at C-5 in compound. Heteronuclear 2D correlation and selective INEPT experiments indicated the need to revise a number of 13C-nmr assignments of pregn-4,16-dien-3,20-dione. Nine indole alkaloids, gelsemine, gelsevirine, 21-oxogelsemine, gelsedine, 14 beta-hydroxygelsedine, gelsenicine, Humantenidine, humantenirine, and koumidine were found to be inactive in the KB and P-388 cytotoxicity test systems.
Ultrasound/microwave-assisted extraction and comparative analysis of bioactive/toxic indole alkaloids in different medicinal parts of Gelsemium elegans Benth by ultra-high performance liquid chromatography with MS/MS.[Pubmed:24375943]
J Sep Sci. 2014 Feb;37(3):308-13.
Indole alkaloids are the main bioactive/toxic components in Gelsemium elegans Benth. To determine the distribution and contents of indole alkaloids in its different medicinal parts, a novel and rapid method using ultra-high performance LC (UPLC) with MS/MS has been established and validated with an optimized ultrasound/microwave-assisted extraction method. Four constituents, namely, Humantenidine, humantenmine, gelsemine, and koumine, were simultaneously determined in 6 min. Chromatographic separation was achieved on an ultra-high performance LC BEH C18 column with a gradient mobile phase consisting of methanol and water (containing 0.1% formic acid both in methanol and water) at a flow rate of 0.3 mL/min. The detection was performed on a triple quadrupole electrospray MS/MS by positive ion multiple-reaction monitoring mode. All the analytes showed good linearity (r >/= 0.9934) within a concentration range from 0.1-25 mug/mL with a LOQ of 25-50 ng/mL. The overall intra- and intervariations of four components were <4.7% with an accuracy of 97.3-101.3%. The analysis results showed that there were remarkable differences in the distribution and contents of four chemical markers in the roots, stems, and leaves of G. elegans Benth. The findings can provide necessary and meaningful information for the rational utilization of its resources.
