摘要: 从野生真菌蓝黄红菇Russula cyanoxantha Schaeff. Fr.子实体中分得6个化合物,经光谱法分别鉴定为4个麦角甾醇:5α,8α-epidioxy-(22E,24R)-ergosta-6,22-dien-3β-ol 1,5α,8α-epidioxy-(24S)-ergosta-6-en-3β-ol 2,(24S)-ergosta-7-ene-3β,5α,6β-triol 3,(22E,24R)-ergosta-7,22-dien-3β,5α,6β-triol 4 (cerevisterol)以及D -阿洛醇 (D-allitol)和硬脂酸 (stearic acid )。其中化合物1 、2为麦角甾醇过氧化物。3和D-阿洛醇为首次发现存在于高等真菌中。

Abstract: Four know ergosterols,5α,8α-epidioxy-(22E,24R)-ergosta-6,22-dien-3β-ol 1,5α,8α-epidioxy-(24S)-ergosta-6-en-3β-ol 2,and (24S)-ergosta-7-ene-3β,5α,6α-tirol 3,(22E,24R)-ergosta-7,22-dien-3β,5α,6α-riol and D-allitol and stearic acid have isolated from the fruiting bodies of Russula cyanoxantha,their structures were determined by means of spectral methods. It is the first to eport the report the isolation of compound 3 and D-allitol from higher fungi.
