C7H,4N203, Mr 174.20, mp. 217-218 C (decomp.), [a]Q 4-8.7° (H2O). A component of leaves of the tea plant (Camellia sinensis), also occurring in the finit bodies of the fungus Xerocomus badius. Biosynthesis From Glu, ethylamine, and ATP. Ethyl-amine in tea shoots probably originates from L-Ala by the action of alanine decarboxylase In green tea T. 

The pigments responsible for the chocolate brown colour of the cap of the bay bolete (Xerocomus badius) and other boletes have been investigated (594). Extraction of the cap skins with a mixture of acidified methanol and acetone yielded a reddish-brown solution from which the pigments could be separated and purified by chromatography on Sephadex LH-20. 

The biosynthesis of badione-A seems to occur via oxidative dimer-isation of xerocomic acid (72). The feasibility of this hypothesis has been demonstrated in vivo by applying an aqueous solution of xerocomic acid to the cap of Xerocomus badius from which part of the...
