In a search for minor ryanoids from the plant Ryania Speciosa Vahl, we recently characterized 11 new members of that family of natural compounds. Most of them represent ryanodine (1) and dehydroryanodine (2) with a modified stage of oxidation in ring C. A second member of the new 4-deoxy series has been identified.Key words: minor natural ryanoids, ryanodine, dehydroryanodine, deoxyryanoids.
