摘　　要：本文采用硅胶柱层析、重结晶等操作,从烟叶粗提物中制得精品茄尼醇;利用1HNMR鉴定了结构;研究了茄尼醇精品及粗品的稳定性;考察了提取方法、提取溶剂、提取时间、溶剂液固比等对烟叶中茄尼醇粗品提取率的影响。结果表明:茄尼醇精品储存稳定性较差;水洗有利于提高粗品茄尼醇粗品的提取率和质量;正己烷-乙酸乙酯溶剂系统在浸泡时间为21h左右,液固比为20mL/g左右的工艺条件较佳。Solanesol was isolated from tobacco extracts via column chromatography, followed by crystallization, and identified by Nuclear Magnetic Resonance Spectroscopy. we studied the stahility of pure solanesol and coarse solanesol, the influence of extraction method, extraction solvent, the proportion of liquid-solid and extration time. The resuhs showed that the stability of pure solanesol is not very. good, washing of the tobacco leaves is good to improving the quality and extraction yieht of the tobacco extraction, the extraction yield is higher under hexane-acetic ether sovent systerm, and the corresponding extration condition is about 21 h, proportion of liquid-solid is about 20 mL/g.
