The method comprises the following steps: pretreating peony shells, and then extracting peony oil from the peony shells by a supercritical carbon dioxide extraction method, or extracting black pigment and lignan from the peony shells, or preparing the peony shells into activated carbon. The method provided by the invention has the beneficial effects that by adopting the supercritical carbon dioxide extraction method to extract the peony oil from the peony shells, the original discarded peony shells are converted into the peony oil of nutritional value or black pigment and lignan, or prepared into activated carbon, so that the waste is changed into valuable, the economic value is created, and the comprehensive utilization of the peony shells is realized.
Description
Technical field
What the invention belongs to the tree peony shell utilizes the method field, is specifically related to a kind of method of comprehensive utilization of tree peony shell.
Background technology
Tree peony (Paeonia suffruticosa) belongs to Paeoniaceae, Paeonia, is traditional famous flower of China, also is world-renowned flowers, is respectfully called " king in spending ".China is original center and the distribution center of world's tree peony wild species, also is the cultivation center of world's tree peony garden-variety.
Since the reform and opening-up, under government supported joint efforts with vast tree peony scientific and technical personnel energetically, China's tree peony industry had obtained further developing.But for a long time, China tree peony only externally exchanges, sells with Fresh Cutting flower with seedling, small part flower forcing, except as view and admire be used as medicine with root, the development and use of other side are less, deep level development is almost blank especially, the tree peony purposes is restricted, and ample resources is in idle or wastes.The tree peony shell is exactly wherein important recycling resource.
The tree peony shell is the accessory substance after the shelling before the peony seeds oil expression, and to set seeds in tree peony year about 600,000 kilograms, the tree peony shell can reach several ten thousand kilograms, and these tree peony shells are taken as discarded object and abandon, and it are not further developed, and have caused the waste of resource.At present domestic research to the tree peony shell also is blank out.And fact proved that the tree peony shell also has potential development and application values.Research is found, contains the tree peony oil of a great deal of in the tree peony shell, contains abundant oleic acid, linoleic acid plus linolenic acid.Tree peony shell color is pitch-black shinny, can extract the black pigment of the inside.Lignan is contained in tree peony shell the inside, can extract lignan.Can also utilize in addition the tree peony shell to make active carbon.Therefore, be badly in need of these waste resources are redeveloped, excavate its potential value, promote China's tree peony industry deeply to develop.Under this background, the present invention proposes a kind of method of comprehensive utilization of tree peony shell just.
Supercritical fluid refers to that temperature and pressure is in critical-temperature and the above fluid of critical pressure, the high density that had both had similar liquids, also have the low viscosity of similar gas, high diffusion coefficient and good permeability, utilize the physicochemical properties of this uniqueness, dissolving power to Cucumber improves greatly, abundant extraction that can the realize target material.And have at low temperatures extract, do not have dissolvent residual and can Selective Separation etc. characteristics.Therefore, utilize CO
2The super critical point technology is proposed oil processing to the tree peony shell, have extraction fully, quality is pure, and easy and simple to handle, particular advantages such as efficient is high, zero pollution.Tree peony oil is new resource food, the utilization of tree peony shell or blank.Tree peony oil industry has risen to the national strategy project, and tree peony shell development and use research should make progress in advance.Therefore for above situation, need to process the tree peony shell, realize the comprehensive utilization of tree peony shell, the grease in the tree peony shell is extracted, or extract black pigment, lignan in the tree peony shell, also the tree peony shell can be made active carbon.Turn waste into wealth, realize its economic worth.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of method of comprehensive utilization of tree peony shell.Adopt supercritical carbon dioxide to the extraction of tree peony shell, from the tree peony shell, extracted the higher tree peony oil of purity, or extract black pigment, lignan in the tree peony shell, also the tree peony shell can be made active carbon.The tree peony shell is turned waste into wealth, realized the comprehensive utilization of tree peony shell, also created economic benefit.
