A C14-polyacetylenic glucoside with an α-pyrone moiety and four C10-polyacetylenic glucosides from Mediasia macrophylla
摘要:
Polyacetylenic glucosides (1-5) were isolated from the MeOH extract of Mediasia macrophylla, and their structures were established by spectroscopic analyses. Compounds 2-4 were the first examples of C-10-polyacetylenic glucosides found in the family Umbelliferae, while compound 1 was a unique polyacetylenic glucoside possessing an alpha-pyrone moiety.
