Abstract
The utility model provides a rapid extraction instrument of trace volatile oil, which integrates the functions of extraction, separation and determination. The rapid extraction instrument consists of an extraction bottle, a separation and determination tube, a spherical condenser tube and a receiving bottle, wherein a water vapor generator is integrated with a distillation extractor to form the extraction bottle; a porous glass clapboard is arranged between the water vapor generator and the distillation extractor; and the spherical condenser tube and the receiving bottle are respectively vertically connected to the upper end and the lower end of the separation and determination tube. Changes of volatile oil components, which are caused by long time contact of a plant sample with liquid water, are avoided, and meanwhile, rapid extraction of high boiling point volatile oil and the separation of volatile oil at different proportions are facilitated. The instrument has the advantages of simple structure, low cost, safe operation, rapidity, convenience, small sample use amount and high extraction rate, and is very suitable for rapidly extracting the trace volatile oil in plant research; and the components have low probability of deterioration.
Description
Technical field
The utility model relates to a kind of ground trace volatile oil rapid extraction device that integrates extraction, separates and measure, and is mainly used in the extraction of odor component in the plant sample.
Background technology
At present, employed volatile oil extractor roughly has three kinds: a kind of is that steam generator and distillation extraction device are isolating, and when water vapor imported in the extractor, temperature reduced, and is unfavorable for that high boiling volatile oil extracts apace.Second kind is that steam generator and distillation extraction device are integrated, but sample is immersed in the boiling water, causes some the composition generation chemical transformation in the sample, thereby can not reflect the chemical feature of volatile oil exactly.The third is prolong and susceptor horizontal positioned, is unfavorable for that the volatile oil of different specific weight separates preferably.
Summary of the invention
In order to overcome the deficiency of above-mentioned volatile oil extractor; The task of the utility model is: design a kind of high boiling point composition that not only can extract effectively in the plant sample; And can accurately reflect the micro-volatile oil extractor of volatile oil chemical feature again, be applied to the rapid extraction of volatile oil in the plant sample.
The utility model solves the technical scheme that task adopted: (1) is combined as a whole steam generator and distillation extraction device; One porous glass partition is arranged therebetween; Plant sample and liquid water are isolated; Liquid water uses NaCl saturated in advance simultaneously, can prevent that so on the one hand the temperature of water vapor from reducing, and is unfavorable for that high boiling volatile oil extracts apace; Also can avoid plant sample and high-temperature water Long contact time on the other hand and cause the variation of some composition; In addition, also can reduce the dissolving of volatile oil in water, improve extraction yield.(2) prolong and receiving flask are connected in the upper and lower end that separates with the mensuration pipe respectively, and vertical the placement, help different specific weight volatilization oil separating.
The utility model is simple in structure, cheap, and operational safety is quick and convenient; Amount of samples is few; Extraction yield is high, and composition is not perishable, can be used for the volatile oil of different specific weight in the rapid extraction plant; Be specially adapted to the research of field sampling, phytovolatilization oil component, also can be used for the extraction experiment of student's plant chemical ingredient.
Description of drawings
Fig. 1 is the structural representation of the described ground trace of the utility model volatile oil rapid extraction appearance.
1. extraction flasks (2000mL) among the figure, 2. the sintered glass dividing plate 3. separates and mensuration pipe (the range of readings 0～10mL of graduated tube, minimum division value 0.1mL), 4. spherical condensation tube (useful length 400mm), 5. stopcock, 6. receiving flask (1000mL).Each glass component junction is ground.
Embodiment
In Fig. 1, a certain amount of zero(ppm) water (use in advance NaCl saturated) is joined in the extraction flask (1), the plant sample of weighing is put on the porous barrier (2) with fat-free filter paper or bind up with gauze again; Give spherical condensation tube (4) the logical water of condensation of going up, heating and extracting bottle (1) is to boiling, and water vapor rises and fully contacts with plant sample, and rising together with volatile oil gets into spherical condensation tube (4); Flow under the cooled oil-water mixture in the graduated tube (3), behind the standing demix, open stopcock (5), emit lower layer of water; Closure piston, the volume of record upper strata volatile oil is opened piston once more, and volatile oil is collected in the receiving flask (6); After the weighing, labelled, give over to analyze and use.
Make the extraction simultaneous test of volatile oil of short handle slender acanthopanax cauline leaf.The result shows that with the extraction yield mean height 25.8% of the utility model trace volatile oil rapid extraction appearance than other volatile oil extraction apparatus, the oxidisability component content is low in the oil, the quality better of oil.
Claims (3)
1. ground trace volatile oil rapid extraction appearance; Form by extraction flask (1), separation and mensuration pipe (3), spherical condensation tube (4) and receiving bottle (6) four parts; It is characterized in that: steam generator and distillation extraction device are combined as a whole; Be porous barrier (2) therebetween, plant sample and liquid water are separated.
2. ground trace volatile oil rapid extraction appearance according to claim 1, it is characterized in that: spherical condensation tube (4) is connected in respectively with receiving bottle (6) and separates and the upper and lower end of measuring pipe (3), and vertical the placement.
3. ground according to claim 1 trace volatile oil rapid extraction appearance is characterized in that: spherical condensation tube (4) directly is connected in the upper end of extraction flask (1), can replaces apparatus,Soxhlet's, be used for the extraction of solid matter composition.
