采用GC-MS分析金丝梅药渣在高温甲醇条件下的解聚液化产物.金丝梅药渣高温甲醇解聚产物所含成分复杂,GC-MS分析共鉴定出116种化合物.化合物的类型主要有酯类、酮类、酚类、苯类、含氮类及其它类化合物,酯类化合物相对质量分数最高,为43.35%,共47种,大部分是甲酯类化合物,其中棕榈酸甲酯(No.95)的相对质量分数最高,达4.48%.甲醇参与了金丝梅药渣高温甲醇解聚反应,同时存在酯化反应和高温萃取作用,金丝梅药渣的高温解聚反应的机理有待更深入的研究.该研究结果为金丝梅化学成分研究及药渣的进一步利用提供了科学依据.
GC-MS was used to analyze the disaggregated liquefaction products of Jinmei dregs under high-temperature methanol conditions.The complex components contained in the high-temperature methanol disintegration products of Jinmei dregs were identified by GC-MS and 116 compounds were identified Mainly esters, ketones, phenols, benzene, nitrogenous and other compounds, the highest relative mass fraction of esters, 43.35%, a total of 47 species, mostly methyl esters, of which palmitic acid Ester (No.95) had the highest relative mass fraction of 4.48% .Methanol was involved in the methanol depolymerization of Metamax by its high temperature, esterification reaction and high temperature extraction at the same time. The high temperature depolymerization reaction The mechanism needs to be further studied.The results of this study provide a scientific basis for the study of the chemical constituents and the further utilization of dregs.
