โฆ Synopsis
A new amino acid betaine clithioneine was isolated from Clitocybe acromelalga.
The structure was determined as 1 by spectral CI analyses and chemical degradations.

A minute amount of the new kainic acid-like amino acids, acromelic acid A (ca. 110 ug) and B (ca. 40 ug), was isolated from the poisonous mushroom Clitocybe acromelalga and their structures were inferred to be 1 and 2\_ respectively by spectral analyses. The poisonous mushroom Clitocybe acromelalga
As a part of studies on physiologically actfve substances produced by mushrooms, we examined constituents of.Clitocybe acromelalga (Japanese name Dokusasako).
