Abstract

A new amino acid (I) was isolated from a toxic mushroom, Russula subnigricans HONGO, and characterized as (2S, 3R) - (-) -3-hydroxybaikiain [(2S, 3R) - (-) -1, 2, 3, 6-tetrahydro-3-hydroxypyridine-2-carboxylic acid]. (S) - (-) -Baikiain (II), (S) - (-) -pipecolic acid (III), ergosterol (IV), ergosteryl peroxide (V) and cerevisterol (VI) were also isolated and identified.
