Abstract
The present invention belongs to the field of plant pesticide, and is especially the microwave extraction process of barbasco compounds. Plant power containing barbasco compounds is mixed with solvent and extracted in microwave instrument for several times, the extraction liquid is filtered and the filtrate is concentrated to obtain the product. The method of the present invention is simple, high in extraction rate, low in cost and less loss of plant material.
Description
Technical field
The invention belongs to the botanical pesticide field, particularly, relate to the extraction of rotenoid.
Technical background
Chemical pesticide has been brought into play enormous function in agriculture production, be the assurance that good harvest is captured in agriculture production.But a large amount of uses along with chemical pesticide have brought multiple detrimentally affects such as pesticide residue, environmental pollution, person poultry poisoning.Botanical pesticide meets the requirement of environment reasonableness agricultural chemicals fully, and it derives from plant, has degradation pathway smoothly at nature, and no negative impact meets the trend and the trend of agricultural chemicals.
Trifoliate jewelvine is a kind of ancient pesticide plant, has brought into play enormous function in agriculture production, its activeconstituents---rotenoid, and active high, pollution-free, to the person poultry safety, there is wide development and utilization prospects in noresidue.But because traditional extracting method such as methods such as Soxhlet extractions, cold soaking extraction need expend a large amount of organic solvents, cause poisoning and environmental pollution easily, and extraction yield is low, makes production cost higher, causes the waste of plant resources.Therefore, how improving existing extracting method, improve the extraction yield of rotenoid, reduce cost, is a problem that presses for solution.
Purpose of the present invention provides that a kind of technology is simple, extraction yield is high, cost is low, the microwave extract method of pollution-free, rotenoid that quality product is high.
Microwave heating has homogeneous heating, speed is fast, and heat is imitated advantages of higher, and the key distinction of microwave heating and other heating is the inside that its heat results from heated material, therefore it has been eliminated in the heat-processed because hot plate, the calorific loss that the thermal conduction of air, wall of container and thermal radiation etc. cause.The microwave extraction method is exactly to utilize the advantage of microwave heating, microwave can be strengthened solvent-extracted efficient, with traditional Soxhlet extracting, cold soaking extract phase ratio, microwave extraction has fast, saves solvent, pollute little, practicable many parts of samples advantage such as handles simultaneously, it helps extracting heat-labile material, and the decomposed sample that can avoid the long high temperature of additive method to cause helps to be extracted material desorb on the sample matrices.
Technology contents
Technical scheme of the present invention: will contain plant oven dry, the pulverizing of rotenoid, and must contain the plant drymeal of rotenoid.Add solvent in the container that fills the plant drymeal that contains rotenoid, dry powder quality and solvent volume are 1: 1～10, then container are put into the microwave instrument, and the range of frequency of microwave is 300MHZ-300GHZ.In 0～60 ℃ temperature range, extract, extracted 1～60 minute at every turn, extract repeatedly, extracting liquid filtering, filtrate merging concentrates, and can obtain product.The plant that contains rotenoid has plants such as Derris plant, Baptisia plant, false indigo platymiscium, Yunnan Caulis Spatholobi platymiscium, shuttle fruit Macroptilium.
Above-mentioned said solvent is: one or more in sherwood oil (I, II), benzene, dimethylbenzene, toluene, naphthalane, butanone, petroleum distillate, camphor oil, essential oil, kerosene, acetone, ethyl acetate, tetracol phenixin, trichloromethane, trieline, ether, methylene dichloride, methyl alcohol, ethanol, dimethyl formamide, propyl carbinol, the normal hexane solvent.
The present invention has the following advantages:
1, because the present invention has adopted advanced microwave extraction technology, extraction ratio of effective constituents is improved greatly, reduced the waste of plant resources.
2, the usage quantity of organic solvent significantly reduces in leaching process, cost is reduced, and pollute and reduce, and concentration process also shortens greatly.
3, traditional extracting method is wanted 24 hours as Soxhlet is extracted, cold-maceration needed 48 hours even the longer time, and the time of microwave extraction obviously reduces, and extraction rate is accelerated.
