    Sulfocostunolide A Description
    Source: The root of Saussurea lappa
    Biological Activity or Inhibitors: Reference standards.
    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).

    Sulfonated guaianolides from Saussurea lappa.[Pubmed: 18520098]
    Two new guaiane-type sesquiterpene lactones with an unusual sulfonic acid group, Sulfocostunolide A (1) and sulfocostunolide B (2), were isolated from the roots of Saussurea lappa. Their structures were elucidated on the basis of extensive spectroscopic analysis.
