Nine known compounds, 5-hydroxy-7-methoxy-2-methyl-4-chromanone (1), 5, 7-dihydroxy-2-methyl-4-chromanone (2), 5-hydroxyl-2-methyl-4-chromanone (3), 1-(2, 6-dihydroxyphenyl)-3-hydroxybutanone(4), 5alpha, 8alpha-epidioxyergosta-6, 22-dien-3beta-ol (5), (22E,24R)-ergost-7, 22-dien-3beta, 5alpha, 6alpha-triol (6), euphorbol (7), beta-sitosterol (8) and 2-(4-hydroxyphenyl) -ethanol (9) were isolated and identified in Xylaria nigripes for the first time, and their structures were mainly determined by MS and NMR methods. Compounds 1 and 2 were isolated as the natural product for the first time.
首次从黑柄炭角菌中分离鉴定出9种已知化合物，分别为5-羟基-7-甲氧基-2-甲基-4-色满酮（1）、5,7-二羟基-2-甲基-4-色满酮（2）、5-羟基-2-甲基-4-色满酮（3）、1-(2,6-二羟基苯基)-3-羟基丁酮（4）、5α,8α-环氧麦角甾-6,22-二烯-3β-醇（5）、(22E,24R)-麦角甾-7,22-二烯-3β,5α,6α-三醇（6）、大戟醇（7）、β-谷甾醇（8）和2-(4-羟基苯基)-乙醇（9），其结构主要通过质谱和核磁共振方法确定。化合物1和2首次作为天然产物被分离得到。
