    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.

    General strategy for synthesis of C-19 methyl-substituted sarpagine/macroline/ajmaline indole alkaloids including total synthesis of 19(S),20(R)-dihydroperaksine, 19(S),20(R)-dihydroperaksine-17-al, and peraksine.[Pubmed: 25247616]

    METHODS AND RESULTS:
    A detailed account of the development of a general strategy for synthesis of the C-19 methyl-substituted alkaloids including total synthesis of 19(S),20(R)-dihydroPeraksine-17-al (1), 19(S),20(R)-dihydroPeraksine (2), and Peraksine (6) is presented. Efforts directed toward the total synthesis of macrosalhine chloride (5) are also reported. Important to success is the sequence of chemical reactions which include a critical haloboration reaction, regioselective hydroboration, and controlled oxidation (to provide sensitive enolizable aldehydes at C-20). In addition, the all-important Pd-catalyzed α-vinylation reaction has been extended to a chiral C-19 alkyl-substituted substrate for the first time.
    CONCLUSIONS:
    Synthesis of the advanced intermediate 64 completes an improved formal total synthesis of talcarpine (26) and provides a starting point for synthesis of macroline-related alkaloids 27-31. Similarly, extension of this synthetic strategy in the ring A oxygenated series should provide easy access to the northern hemisphere 32b of the bisindoles angustricraline, alstocraline, and foliacraline (Figure 4 ).

    Stem bark alkaloids of Rauvolfia caffra.[Pubmed: 6471882]

    METHODS AND RESULTS:
    Thirty two alkaloids were isolated from the stem bark of Rauvolfia caffra and 28 were identified. The alkaloids represented corynane (3), strictamine (1), sarpagan (4), akuammicine (2), pleiocarpamine (1), indolenine (1), dihydroindole (6), Peraksine (3), heteroyohimbine (2), hydroxyheteroyohimbine (2), oxindole (1), 2-acyl-indole (1), suaveoline (3) and yohimbine (2) types. The anhydronium base serpentine was detected but not isolated.
    CONCLUSIONS:
    The principal alkaloids were ajmaline and norajmaline (dihydroindoles), ajmalicinine and ajmalicine (heteroyohimbines), geissoschizol (E-seco indole) and pleiocarpamine and the heteroyohimbine derived alkaloids were predominantly normal configuration compounds. The biosynthetic and ethnopharmacological significance of the alkaloids is discussed.
