-
摘要: 结合水提法和大孔树脂层析法对金银花进行提取分离,通过单因素试验,确定了最佳水提工艺,即料液比1:9,提取温度90℃,提取次数2次;并采用气相色谱/质谱仪联用对此金银致香组分进行分析,共鉴定出38种成分,主要含有芳樟醇、棕榈酸甲酯、棕榈酸乙酯、十八酸乙酯、8,11-十八碳二烯酸甲酯、亚油酸乙酯、亚麻酸甲酯、亚麻酸乙酯、棕榈酸、油酸、亚油酸、(Z,Z,Z)-9,12,15-十八碳三烯-1-醇等.将此致香组分0.05%添加于卷烟中,具有丰富烟香、增加清香香韵、掩盖卷烟杂气、柔和烟气等作用.Abstract: The aromatic components of honeysuckle was prepared by using water extraction method and macroporous resin column chromatography,and the optimal conditions of water extraction process were obtained by single factor experiment:ratio of solid to liquid 1:9,extraction temperature 90℃,extraction 2 times.There were 38 components were identified by GC/MS,the main components were linalool,methyl hexadecanoate,hexadecanoic acid ethyl ester,octadecanoic acid ethyl ester,8,11-octadecadienoic acid methyl ester,linoleic acid ethyl ester,methyl linolenate,linolenic acid ethyl ester,hexadecanoic acid,oleic acid,(Z,Z)-9,12-octadecadienoic acid,(Z,Z,Z)-9,12,15-octadecatrien-1-ol,etc.The 0.05% aromatic components was added into cigerettes as a flavor.The results showed that it could enrich the smokey,enhance the notes of fresh aroma,reduce offensive odor and make the cigarette smoke soft.
