Summary:【目的】分析红贝俄氏孔菌精油化学成分及其抗氧化活性,为红贝俄氏孔菌的综合利用提供科学依据。【方法】联合运用乙醚提取法和水蒸气蒸馏法从红贝俄氏孔菌子实体中提取精油,采用气相色谱—质谱联用技术(GC-MS)分析其化学成分,通过峰面积归一法计算各成分的相对含量,并用羟自由基清除试验评价其抗氧化活性。【结果】从红贝俄氏孔菌精油中鉴定出35种化合物,占精油总量的88.33%,包括脂肪烃7种、芳香烃4种、醇2种、醛3种、酮3种、羧酸及其衍生物10种、含硫化合物2种和萜类化合物4种。精油中相对含量较高的化学成分有(R)-(-)-3-甲基-2-丁醇(49.70%)、4-甲基-4-羟基-2-戊酮(10.57%)、甘菊蓝(8.01%)、甲苯(4.36%)、棕榈酸(4.01%)和(Z,Z)-9,12-十八碳二烯酸(4.01%)。红贝俄氏孔菌精油具有一定的抗氧化活性,对羟自由基的清除能力随精油质量浓度的增加而增强,半数清除浓度(EC50)为2.73 mg/mL。【结论】红贝俄氏孔菌精油化学成分丰富,以羧酸及其衍生物和脂肪烃为主,且具有一定的抗氧化活性,可作为天然抗氧化剂资源进行开发应用。

Objective】The chemical components of essential oil from Earliella scairosa(Pers.) Gilb. Ryvarden were analyzed and its antioxidant activity was evaluated in order to provide theoretical references for its development and utilization.【Method】The essential oil was extracted from fruiting bodies of E.seabrosa(Pers.) Gilb. Ryvarden using ether extraction method and steam distillation method.The chemical components of the essential oil were analyzed by gas chromatography-mass spectrometry(GS-MS) technology,and their relative percentage contents were calculated with peak area normalization method.The antioxidant activity was evaluated by hydroxyl radicals-scavenging
