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

    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.
    Compounds 1 and 7 exhibited moderate cytotoxicity against five human tumor cell lines with IC50 values in the range 4.6-9.3 μM.
    Humantenine Description
    Source: The roots of Gelsemium elegans
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Chemical constituents of aerial parts of Gelsemium elegans.[Pubmed: 21837971]
    To study the chemical constituents from the aerial parts of Gelsemium elegans.
    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).
    Compounds 10-16 were isolated from the genus Gelsemium for the first time.
