Seven ergostane-type sterols and two mono-glucosides were isolated from the ethyl acetate soluble fraction of Lactarium rolemus. Three are previously unknown, i.e. 3-O-beta-D-glucopyranosyl-22E,24R-5alpha,8alpha-epidioxyergosta-6,22-diene, 3-O-beta-D-glucopyranosyl-22E,24R-5beta,8beta-epidioxyergosta-6,22-diene and 22E,24R-ergosta-7,22-diene-3beta,5alpha,6beta,9alpha-tetraol. The structural elucidation of these compounds was mainly achieved by spectroscopic methods.
从乳菇属真菌（Lactarium rolemus）的乙酸乙酯可溶部分中分离出七种麦角甾烷型甾醇和两种单糖苷。其中三种是此前未知的，即3 - O - β - D - 吡喃葡萄糖基 - 22E,24R - 5α,8α - 环氧麦角甾 - 6,22 - 二烯、3 - O - β - D - 吡喃葡萄糖基 - 22E,24R - 5β,8β - 环氧麦角甾 - 6,22 - 二烯和22E,24R - 麦角甾 - 7,22 - 二烯 - 3β,5α,6β,9α - 四醇。这些化合物的结构解析主要通过光谱方法完成。
