  A C,O-diglucosylated oxanthrone from Aloe littoralis

  摘要：

  A new C,O-diglucosylated oxanthrone, named littoraloside, has been isolated from the leaf exudate of Aloe littoralis, along with the previously reported compounds, littoraloin, deacetyllittoraloin and 10-hydroxyaloin B. The structure, including the stereochemistry of littoraloside was established on the basis of spectral analyses, as well as by conversion to deacetyllittoraloin and to 10-hydroxyaloin B by enzymatic and acid catalyzed hydrolysis, respectively.

  Analysis of the leaf exudate of Aloe claviflora resulted in the isolation of a new oxanthrone, 10-hydroxyaloin B 6'-O-acetate (1), whose structure was determined on the basis of spectral evidence as well as by conversion to the known compound 10-hydroxyaloin B (2).
