黄芩内生真菌N.SBA10固体发酵培养物的乙酸乙酯提取物有较好的抗氧化活性。从乙酸乙酯提取物中分离得到3个化合物,根据波谱数据,化合物1-3的结构分别被鉴定为:邻苯二甲酸二正丁酯(DBP),altemariol methyl ether(AME)和altemariol(AOH)。
Ethyl acetate extract (EAE) of the culture ofAlternaria sp. N.SBA10 isolated from Scutellaria baicalensis in solid state fermentation showed good antioxidant activity. Three compounds isolated from EAE were identified as dibutyl phthalate (DBP) (1), altemariol methyl ether (AME) (2) and altemariol (AOH) (3) by nuclear magnetic resonance (NMR) spectral analysis.
