OBJECTIVE
To study the secondary metabolites of mangrove endophytic fungus SK5.
METHODS
The compounds were isolated by chromatographic technique. Their structures were identified by comprehensive physico-chemical properties and spectroscopic methods.
RESULTS
Five compounds were isolated and identified as 2,8-dihydroxy-3,4-dihydronaphthalen-1(2H)-one(1), Sclerotinin A (2), dihydrocitrinone(3), 4-hydroxybenzaldehyde (4) and 3-hydroxy-2-methylbenzoic acid (5).
CONCLUSION
Compound 1 is isolated from nature for the first time.
目的
研究红树林内生真菌SK5的次生代谢产物。
方法
采用色谱技术分离化合物。通过综合物理化学性质和光谱方法鉴定其结构。
结果
分离并鉴定出5种化合物，分别为2,8-二羟基-3,4-二氢萘-1(2H)-酮(1)、核盘菌素A(2)、二氢柑橘酮(3)、4-羟基苯甲醛(4)和3-羟基-2-甲基苯甲酸(5)。
结论
化合物1首次从自然界中分离得到。
