Question: There have been several queries about apple seeds and that they 
contain cyanide. I have heard that peach pits and bitter almonds also contain 
cyanide. Has anyone conducted analysis of a whole apple or a measured quantity 
of apple seeds and determined the amount of cyanide present (ppm, ppb)?

Abstract
Laetrile preparations obtained from a cyanide intoxicated patient were analyzed for their 
cyanide content by a microdiffusion colorimetric procedure. Cyanide was also determined in 
apricot, peach and apple seeds. The results were compared to those reported in the 
literature for cyanogenic glycoside containing seeds.
