The toxicity of ryanodine (1) and 9,21-didehydroryanodine (2) (the principal active ingredients of the botanical insecticide ryania) to adult female house Γies (Musca domestica L.) is attributable to binding to the ryanodine receptor (ryr) and thereby disrupting the Ca2`-release channel. These ryano
## Abstract A method for preparing tritiumβlabelled ryanodine is described. The alkaloid was first brominated, and the bromoryanodines were separated from the reaction mixture by thin layer chromatography; NMR analysis at this stage showed substitution of pyrrole protons by bromine. Bromoryanodine
The commercially available preparation of the naturally occurring diterpene ester ryanodine contains several compounds in addition to ryanodine. In the present study these compounds were separated and purified using high performance liquid chromatography. The two major components, ryanodine and dehy
