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.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Koumine, Humantenine, and Yohimbane Alkaloids from Gelsemium elegans.[Pubmed: 26103517]

J Nat Prod. 2015 Jul 24;78(7):1511-7.


METHODS AND RESULTS:
Nine new alkaloids of the koumine (1-4), Humantenine (5-7), and yohimbane (8, 9) types as well as 12 known analogues were isolated from the leaves and vine stems of Gelsemium elegans. Compound 1 is the first N-4-demethyl alkaloid of the koumine type, compound 7 is the first nor-Humantenine alkaloid, and compounds 8 and 9 are the first N-1-oxide and the first seco-E-ring alkaloids, respectively, of the yohimbane type.
CONCLUSIONS:
Compounds 1 and 7 exhibited moderate cytotoxicity against five human tumor cell lines with IC50 values in the range 4.6-9.3 μM.

Chemical constituents of aerial parts of Gelsemium elegans.[Pubmed: 21837971]

To study the chemical constituents from the aerial parts of Gelsemium elegans.
METHODS AND RESULTS:
Compounds were isolated and purified by repeated column chromatography, as well as semiprep arative HPLC, and their structures were identified by physicochemical properties and spectroscopic methods, such as NMR and MS. Sixteen compounds were obtained and identified from G. elegans, including nine alkaloids: koumine (1), gelsenicine (2), 19-(Z)-akuammidine (3), gelsemoxonine(4), gelsemin (5), gelsevirine (6), Humantenine (7), 11-methoxygelsemamide (8) and gelegamine D (9). Three megastigmane glycosides: (3R, 5S, 6S, 7E, 9R)-megastigman-7-ene-3, 5, 6, 9-tetrol-9-O-beta-D-glucopyranoside (10), (6R, 7E, 9R)-9-hydroxy-4, 7-megastigmadien-3-one-9-O-[alpha-L-arabinopyranosyl-(1 --> 6)-beta-D-glucopyranoside] (11) and (6S, 7E, 9R) -6, 9-dihydroxy-4, 7-megastigmadien-3-one-9-O-[alpha-L-arabinopyranosyl-(1 --> 6) -beta-D-glucopyranoside] (12). Two flavone C-glycosides: orientin (13) and isorientin (14); one iridoid glycoside, sweroside (15) and one fructoside, n-butyl-alpha-D-fructofuranoside (16).
CONCLUSIONS:
Compounds 10-16 were isolated from the genus Gelsemium for the first time.
