摘要

采用气相色谱-质谱联用技术对大西洋杉焦油进行了分析,测定了其总多酚和缩合单宁的含量、还原铁的抗氧化能力和总抗氧化能力。化学性质鉴定出88种化学成分,其中喜马马烯和α-大西洋酮异构体(14.51% ~ 4.07%)、钙硅烯(3.52%)和ar-Turmerone(3.35%)为主要成分;总多酚含量为57.15±0.15毫克当量没食子酸/g焦油,缩合单宁含量为4.41±0.05毫克当量儿茶素/g焦油,有效浓度为50±0.075毫克/mL±0 00028,总抗氧化能力为262.75毫克当量抗坏血酸/g焦油±14,43。实验结果表明,我们的焦油具有促进抗氧化活性。

Chemical Characterization and Antioxidant Activity of Cedrus atlantica Manetti Tar (Atlas Cedar Tar)
Cedrus atlantica Manetti Tar was analyzed by gas chromatography coupled to mass spectrometry, it was subjected to analyzes to know their total polyphenolic and condensed tannins contents, also their Ferric-reducing antioxidant power and Total antioxidant capacity. Chemical characterization identified 88 constituents where Himachalene and α-atlantone isomers (14.51 % - 4.07 %), Calacorene (3.52 %) and ar-Turmerone 3.35 %, were the major components, the total polyphenolic content and condensed tannins contents were 57.15 ± 0.15 milligrams equivalent of gallic acid /g tar and 4.41 ± 0.05 milligrams equivalent of catechin /g tar respectively .This extract showed remarkable Ferric-reducing antioxidant power with effective concentration equal to 50 ± 0.075 mg /mL ± 0,00028 and total antioxidant capacity equal to 262.75 mg equivalents of ascorbic acid /g tar ± 14,43. The experimental results indicated that our tar has promotive antioxidant activity.
