A chloro amino acid from Amanita solitaria

Phytochemistry
1972.0

Abstract

The mushroom Amanita solitaria contains in excess of 1000 ppm 2(S)-amino-4,5-hexadienoic acid (I), 300 ppm trans-2-amino-5-chloro-4-hexenoic acid (II), and a chloride ion concentration (2000 ppm) significantly greater than that found in other basidiomycetes. I can be converted into II in hydrochloric acid, but II is not an artifact of isolation.
