中文摘要：

对一株红树林来源的产油脂真菌PJx-29发酵产物中的抗氧化成分进行分离和鉴定。利用溶剂萃取、硅胶柱色谱及制备HPLC等分离手段从发酵产物中分离得到2个甘油酯类化合物和其他5个化合物，通过理化性质分析及渡谱学方法鉴定其化学结构分别为：十五碳单甘油酯，9”，12”一十七碳二烯酸，十六烷基甘油酯，6-戊基-仪-吡喃酮，4，6-二羟基-9，10-二甲基苯乙酮，双（8—8’-7羟基-4-甲氧基-5-甲基香豆素），对羟基苯甲酸，6-氨基苯甲醛，并以DPPH法评价了化合物的抗氧化活性，结果表明化合物1，化合物2和化合物6具有较强的抗氧化活性，其Ic50分别为：（11．38±0．61）、（9．33±0．80）和（11．12±1．01）μg／mL。

英文摘要：

The antioxidant components duction fungus PJX -29 derived from Ocean were isolated and identified from the fermentation product of the Oil pro- Mangroves. Two glyceride compounds and other five compounds were iso- lated with solvent extraction, silica gel column chromatography and preparative HPLC and their structures were identi- fied as monoglycerides ,9＂, 12＂ - Heptadecadienoic acid, 1 - （hydroxymethyl） - 2 - [ （ 1 - oxohexadecyl） oxy ] ethyl ester,6 - Pentyl - ct - pyrone ,4,6 - dihydroxy - 9,10 - dimethylacetophenone, bis [ 8 - 8＇ - （7 - hydroxy - 4 - me- thoxy -5 -methylcoumarin） ] , Hydroxybenzoic acid ,6 -Aminobenzaldehyde by physicochemical properties and spec- tral analyses, respectively. The antioxidant activity of the compounds were evaluated by DPPH method, the result showed that compounds 1,2 and 6 have potential antioxidant activity, and their ICs0 are （ 11.38 ± 0.61 ）, （9.33 ± 0.80） and （ 11.12 ± 1.01 ） μg/mL,respectively.
