摘要/Abstract

摘要： 亚麻（Linum ustitatissimum Linaceae）籽富含木酚素。木酚素（Lignans）是一种植物雌激素,具有抗癌及预防心血管疾病等方面显著药效。对亚麻木酚素提取方法的研究,具有十分重要的意义。实验采用乙醇回流提取法、乙酸乙酯超声提取法,并对提取液进行硅胶柱净化结果检测。结果表明,乙醇回流提取法,出峰时间在2～6min,硅胶柱净化结果检测,回收率均值为83.3%;乙酸乙酯超声提取法,出峰时间在2～4min,提取样品不完全,需在超声波时间、水浴温度、浓缩温度控制范围等方面进行深入的研究。

Abstract: Linum ustitatissimum Linaceae, known as fax, is rich in lignan in its seeds. As a kind of phytoestrogens , lignan plays an important role in anticancer, antitumor and anti-cardiovascular disease. Therefore, it is significant in conducting the research of extraction. In this experiment, we studied the extraction of SDG from flaxseeds by using the ethanol refluxing extraction （ERE） and ultrasonic acetidin extraction （AE） methods. Extracts were purified by silica gel column. The results show that： the peaking time of SDG is between 2-6 minutes and the recovery rate is 83.3% by using ERE, the peaking time of SDG is between 2-4 minutes and the extraction is incomplete by using AE. Further research needs to be done on ultrasonic time, water bath time and enrichment temperature.
