Optimization Study of Simultaneous Distillation Extraction Technology of Concrete in Cestrum Nocturanum Flower
摘要
Abstract
In order to enhance extraction efficiency and quality of spice in Cestrum nocturanum flower,the extraction optimization of Cestrum nocturanum flower concrete is studied by using simultaneous distillation extraction which is based on uniform experimental design,and gas chromatography-mass spectrometry(GC-MS) is used to analyze volatile compounds of Cestrum nocturanum flower concrete.The results show that the best extraction conditions are as follows:solid-liquid ratio is 1:15 g/g,extraction time 4.5 h,extraction solvent consump-tion 61 g,salting-out 20 g,and the predicted yield in the optimal conditions is 1.54%,close to the observed yield 1.52%.The results of GC-MS analysis show that 23 kinds of chemical composition are tested out in Cestrum nocturanum flower concrete,mainly consisting of alkenes,acids and alcohols,and the content of dipentene is the highest,up to 41.94%.Given above,it is advisable to employ this opti-mized process of simultaneous distillation extraction to extract spice in Cestrum nocturanum flower.Its extraction rate is higher in the optimal extraction conditions,and the concrete sample has intense flavor of Cestrum nocturanum flower.关键词
