Structure Elucidation of a New Bufadienolide Toxin From the Flowers of Bryophyllum-Tubiflorum Harv (Crassulacea)
Bryotoxins-B and Bryotoxins-C, Toxic Bufadienolide Orthoacetates From the Flowers of Bryophyllum-Tubiflorum (Crassulaceae)
A mixture of bryotoxins B and C, two new toxins from the flowers of Bryophyllum tubiflorum, was resolved after acetylation and semipreparative silica h.p.l.c. Spectroscopic analysis of the isolated acetates resulted in identification of the toxins as the bufadienolide orthoacetates (3) and (4)
