从白黄小脆柄菇(Psathyrellacandolleana)发酵液提取物的乙酸乙酯层中分离得到一个新的血苋烷型倍半萜(1)和一个已知的没药烷型倍半萜(2)。通过质谱、核磁等方法确定化合物1的结构为15-hydroxy-drimenol。通过文献对照核磁数据确定化合物2为1α-hydroxy-bisabola-2,10-dien-4-one。
A new amaranth-type sesquiterpene (1) and a known myrrh-type sesquiterpenoid (2) were isolated from the ethyl acetate layer of the extract of Psathyrella candolleana fermentation broth. . The structure of compound 1 was confirmed to be 15-hydroxy-drimenol by mass spectrometry, nuclear magnetic resonance and the like. Compound 2 was determined to be 1α-hydroxy-bisabola-2,10-dien-4-one by reference to the nuclear magnetic data.
