| 中文摘要: |
| 为进一步研究和利用具有杂草生防潜力的狗尾草平脐蠕孢Bipolaris setariae菌株NY1，对其次级代谢产物进行了分离与结构鉴定。从菌株NY1的大米发酵的乙酸乙酯提取物中分离到7个化合物，通过波谱分析将其分别鉴定为：邻苯二甲酸二异壬酯，麦角甾-5,7,22-三烯-3β-醇，5α,8α-过氧化麦角甾-6,22-二烯-3β-醇，6-甲基苯-1,2,4-三酚，3-脱羟基蛇孢菌素A，邻羟基苯甲醛，蛇孢菌素I。其中3-脱羟基蛇孢菌素A是一种植物毒素，而具有抗癌、抗菌作用的蛇孢菌素I的产量较高，具有工业化生产的潜力。 |

| Secondary metabolites of Bipolaris setariae NY1 strain with herbicidal potential were isolated and identified. Seven compounds were obtained from the ethyl acetate extract of rice-fermented B. setariae and they were determined as diisononyl phthalate, ergosta-5,7,22-trien-3β-ol, 5α,8α-epidioxyergosta-6,22-diene-3β-ol, 6-methylbenzene-1,2,4-triol, 3-anhydroophiobolin A, 2-hydroxybenzaldehyde, and ophiobolin I by extensive spectroscopic analysis. Among them, 3-anhydroophiobolin A was the primary phytotoxin. Ophiobolin I with antitumor and antifungal effects, is highly yielding, displaying potentiality for industrial production. |
