摘要
目的:对厚朴的有效成分进行提取分离与结构鉴定。方法:用超声法提取厚朴中的厚朴酚、和厚朴酚,用聚酰胺柱层析分离提取物,用反相-高效液相色谱法对其进行含量测定与结构鉴定。结果:用中等强度超声波、95%乙醇、8倍量溶酶提取3次,每次30min即可很好地提取厚朴药材中厚朴酚及和厚朴酚。总酚、厚朴酚及和厚朴酚的提取率(按原药材质量计算)分别为1.92%、1.26%、0.66%。用聚酰胺柱层析可分离得到和厚朴酚单体。结论:本方法操作简便、稳定性高,可为厚朴有效成分的提取分离及结构鉴定提供理论依据。
OBJECTIVE: To extract effective constituent of Magnolia offcinalis and to identify its structure.METHODS: Ultrasound extraction was used to extract magnolol and honokiol from M.officinalis and the extracts were isolated using polyamide column chromatography.The content of magnolol and honokiol were determined using RP-HPLC.RESULTS: The optimal extractive condition was moderate ultrasonic,95% alcohol,8-fold solvent,extracting for three times,each time for 30 min.The extraction rates of phenols,magnolol and honokiol were 1.92%,1.26% and 0.66%,respectively.Honokiol was obtained by polyamide column chromatography.CONCLUSION: The method is simple,stable and supply reference for the extraction and identification of M.officinalis.
