The ethyl acetate soluble fraction obtained from the hot water extract of Picea mariana bark (BS-EAc(f)) has been demonstrated to have anti-inflammatory and antioxidant properties. Thus, in the current study, we isolated and characterised major compounds of this fraction by HPLC, NMR and MS analyses. On the whole, 28 compounds were identified, among which were five neolignans, seven lignans, trans-resveratrol, three phenolic acids and four flavonoids. To the best of our knowledge, 2,3-dihydro-3-(4-hydroxy-3-methoxyphenyl)-2-(hydroxymethyl)-(2S,3S)-1,4-benzodioxin-6-propanol, threo and erythro 3-methoxy-8,4'-oxyneolignan-3',4,7,9,9'-pentol, pallasiin, (±) epi-taxifolin, homovanillyl alcohol, orcinol and 2-[4-(3-hydroxypropyl)-2-methoxyphenoxy]-1,3-propanediol are reported for the first time in the Picea genus. P. mariana dry bark contains at least 104μgg(-1)dw of trans-resveratrol and it could be therefore considered as a new accessible source of this molecule. This study provides novel information about the identity of major compounds present in BS-EAc(f), which is essential for the understanding of the anti-inflammatory and nutraceutical potential of this extract.
从黑云杉树皮热水提取物中获得的乙酸乙酯可溶部分（BS-EAc(f)）已被证明具有抗炎和抗氧化特性。因此，在本研究中，我们通过 HPLC、NMR 和 MS 分析分离并表征了该部分的主要化合物。总的来说，鉴定出了 28 种化合物，其中包括 5 种新木脂素、7 种木脂素、反式白藜芦醇、3 种酚酸和 4 种类黄酮。据我们所知，2,3-二氢-3-(4-羟基-3-甲氧基苯基）-2-（羟甲基）-(2S,3S)-1,4-苯并二恶烷-6-丙醇、苏式和赤式 3-甲氧基-8,4'-氧新木脂素-3',4,7,9,9'-戊醇、pallasiin、(±）表儿茶素、香草醇、没食子酸和 2-[4-(3-羟丙基）-2-甲氧基苯氧基]-1,3-丙二醇均首次在黑云杉属中报道。云杉干皮至少含有 104μg·g(-1)dw 的反式白藜芦醇，因此可以被认为是这种分子的新的可利用来源。本研究提供了 BS-EAc(f)中主要化合物的身份的新信息，这对于理解该提取物的抗炎和营养潜力至关重要。
