【摘要】:采用鹽析輔助水蒸氣蒸餾法(salt out-assisted steam distillation,SOSD)制備紅松殼揮發(fā)油,探討無機(jī)鹽對蒸餾方式的影響,通過單因素試驗(yàn)研究了蒸餾時間、固液比、無機(jī)鹽、磷酸氫二鈉的質(zhì)量濃度、萃取劑等因素對紅松殼揮發(fā)油提取率的影響,并采用氣相色譜-質(zhì)譜聯(lián)用技術(shù)對紅松殼揮發(fā)油成分進(jìn)行分析。結(jié)果表明:SOSD法最佳制備工藝條件為蒸餾時間3 h,固液比1∶9(g/m L),鹽析效果最好的無機(jī)鹽為4×10-3g/m L磷酸氫二鈉,在此條件下紅松殼揮發(fā)油提取率為0.9%,是水蒸氣蒸餾法(steam distillation,SD)制備紅松殼揮發(fā)油提取率(0.64%)的1.4倍。紅松殼揮發(fā)油成分分析表明:SOSD法提取紅松殼揮發(fā)油共分析出17種可能成分,而SD提取紅松殼揮發(fā)油共分析出16種可能成分,兩種方法提取結(jié)果有9種相同可能成分,如反-α反-α,α-5-三甲基-5-乙烯基四氫化-2-呋喃甲醇、苯甲醛、左旋樟腦、2-茨醇、(1R)-(+)-諾蒎酮、2,6,6-三甲基雙環(huán)[3.1.1]庚-2-烯、2-(4-甲基苯基)丙-2-醇、4,6,6-三甲基二環(huán)[3.1.1]庚-3-烯-2-酮、3-甲基-6-(1-甲基亞乙基)-2-環(huán)己烯-1-酮等,其相對百分含量差別不大。
[Abstract]:The essential oil of Pinus koraiensis hulls was prepared by salting-out assisted steam distillation (out-assisted steam distilling). The influence of inorganic salt on distillation mode was studied by single factor experiment. The effects of distillation time, solid-liquid ratio, inorganic salt, sodium hydrogen phosphate and extractant on the extraction rate of volatile oil from Pinus koraiensis hulls were studied. The components of volatile oil from Pinus koraiensis shell were analyzed by gas chromatography-mass spectrometry. The results showed that the optimum preparation conditions were as follows: distillation time 3 h, solid-liquid ratio 1: 9 g / mL). The best salt for salting-out was 4 脳 10 ~ (-3) g / m ~ (-1) sodium hydrogen phosphate. Under this condition, the extraction rate of volatile oil from Korean pine shell was 0.9%. Steam distillation. The extraction rate of volatile oil from Korean pine shell was 1.4 times higher than that from Korean pine shell by SD.The analysis of volatile oil composition of Korean pine shell showed that 17 possible components were obtained by extracting volatile oil from Pinus koraiensis hulls by the method of 1: SOSD. SD extraction of Korean pine shell volatile oil analysis of a total of 16 possible components, two methods of extraction results of the same 9 possible components, such as trans-偽-偽-偽. 偽 -5-trimethyl-5-vinyltetrahydro-2-furan methanol, benzaldehyde, levocamphor 2-zinol, 1R ~ (-)-. [3.1.1] heptyl-2-olefin 2-butadiene 4-methylphenyl) propyl-2-propanol 6-trimethyl dicyclo. [3.1.1 the relative content of heptyl-3-ene-2-keto-3-methyl-6-butadiene-1-methyl-1-methylene-2-cyclohexene-1-one has little difference in relative percentage.
