对东北两种泥炭(桦甸草本泥炭、伊春藓类泥炭)超临界萃取物进行了元素分析、平均分子量测定、红外分析和~1HNMR分析,并对桦甸泥炭萃取物中正己烷可溶物进行了GC-MS分析。结果表明,萃取物中含有脂肪族结构、芳香结构、大量含氧基团,并含有脂环化合物。桦甸泥炭萃取物平均分子量为325,芳碳率为0.34,芳香结构以单环为主;伊春泥炭萃取物平均分子量为315,芳碳率为0.52。 The elemental analysis, average molecular weight, infrared analysis and ~ 1HNMR analysis of the supercritical fluid extracts from two peat species (Huadian meadow peat and Yichun moss peat) in Northeast China were carried out. The effects of n-hexane solubles GC-MS analysis was performed. The results show that the extract contains aliphatic structure, aromatic structure, a large number of oxygen-containing groups, and contain alicyclic compounds. The average molecular weight of Huadian peat extract was 325, the aromatic carbon rate was 0.34, and the aromatic structure was mainly single ring. The average molecular weight of Yichun peat extract was 315 and the aromatic carbon rate was 0.52.
