    Description: 21,23-Dihydro-23-hydroxy-21-oxozapoterin is a natural product from Clausena excavata Burm. f.
    21,23-Dihydro-23-hydroxy-21-oxozapoterin Description
    Source: The aerial parts of Clausena excavata Burm. f.
    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).

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.

    Tetranortriterpenoids from Clausena excavata.[Reference: WebLink]

    Five new tetranortriterpenoids, (11β)-21,23-dihydro-11,21-dihydroxy-23-oxoobacunone (=21,23-dihydro-21-hydroxy-23-oxozapoterin; 2), (11β)-21,23-dihydro-11,23-dihydroxy-21-oxoobacunone (=21,23-Dihydro-23-hydroxy-21-oxozapoterin; 3), (1α,11β)-1,2,21,23-tetrahydro-1,11,23-trihydroxy-21-oxoobacunone (=21,23-dihydro-23-hydroxy-21-oxoclausenarin; 4), (1α,11β)-23-ethoxy-1,2,21,23-tetrahydro-1,11-dihydroxy-21-oxoobacunone (=23-ethoxy-21,23-dihydro-21-oxoclausenarin; 5); (11β)-1,2,21,23-tetrahydro-11,23-dihydroxy-21-oxoobacunoic acid; 6), were isolated from the aerial part of Clausena excavataBurm. f. (Rutaceae).
    All compounds possessed 3,4-seco skeletons. Their structures were established by spectroscopic studies. Tetranortriterpenoids with a 4-hydroxybut-2-eno-4-lactone moiety are rarely found in the genus Clausena.
