Abstract
The present invention relates to a method for preparing a natural fungicidal agent. The present invention has the preparing process of extracting essence from the fresh leaves of plants by a steam distillation method and making use of specific plant resources in China and adding ethanol, propanediol or glycerol. The natural fungicidal agent has the advantages of high fungicidal efficiency, strong bacteriostasis and sterilization capability, low dosage, long fungicidal period, high safety and no toxicity. The natural fungicidal agent is especially suitable for the fields of tobacco, pharmaceuticals, foods, fruits, vegetables, storehouses for rice and cotton, daily chemicals, books, files, etc.
Description
The present invention relates to a kind of preservation mould inhibitor.It is applicable to the mildew-resistant of aspects such as tobacco, pharmaceuticals, food, beverage, fruit and vegetable, grain and cotton warehouse, daily chemicals and book and file, also can be used as family's mildew-resistant and air cleaning agent.
Before not having this invention, mold-proof method commonly used has two kinds: a kind of is physical method, and promptly freezing, low-temperature preservation, airtight package, air ionization and anion generator have bigger limitation.Another kind is a chemical method, and chemical anti mildew agent is toxic, and is harmful to health, and it is poor that mildew-resistant is renderd a service.Through inventor's retrieval, do not see a kind of process for preparing natural fungicidal agent and be disclosed.
The present invention utilizes Chinese distinctive plant resources in order to address the aforementioned drawbacks, and by the compounding method of biological fine chemistry industry, anti-mold effect is good, the preservation time long, avirulent mildew-resistant problem thereby solved.
Content of the present invention (in conjunction with the embodiments) realizes by following technical proposals:
Utilize the bright leaf of silver-colored wood or broad-leaved camphor tree as raw material.Place the ground of shady and cool ventilation to divide on silver-colored wood or the bright leaf of broad-leaved camphor tree plucked, thickness is below the 40cm, deposited 12-48 hour, stirred once in every interval 2-4 hour, become leather hard after, silver-colored wood or the bright leaf of the broad-leaved camphor tree steam gas of packing into is carried that (still is high 1.2 meters in the distillation still of equipment, thick 80 centimetres of footpath), add cold water to the sieve plate (metal) 4-6 centimetre at the bottom of the still in the pot, a pot flame enrichment down heats up, and fuel is coal or firewood.When water temperature rises to 100 ℃ in the still, from the curved tube outlet on kettle cover top, begin to have steam to discharge, after cooling, the plants essential oil liquefy of steam and steam state, distillate oozes (control enters the cold water flow in the condenser, regulates distillate and temperature and is lower than below 30 ℃) from the end of condenser pipe.Every still was ceased fire after heating 4-6 hour, promptly finished gas and carried, and obtained silver-colored wood or broad-leaved camphor leaf oil, through after leaving standstill 12-14 hour, formed oil-water interfaces, was water white water layer on the interface, and the interface is flaxen plants essential oil (proportion is greater than water) down.With oil water separator plants essential oil and moisture are left, obtain the raw material that plants essential oil is made natural fungicidal agent.Test by analysis, the oil yield of cinnamomum septentrionale hand. mazz. leaf essential oil is 1.1%, contain 30 compositions altogether, its Main Ingredients and Appearance has 14 kinds: trans-methylisoeugenol 85.71%, methyl eugenol 6.36%, linalool 1.12%, β-cloves alkene 0.89%, cis-methylisoeugenol 0.74%, β-cadinene 0.60%, yellow camphor tree, oil element 0.58%, ledol 0.51%, 1.68-cineole 0.4%, australene 0.04%, sabinene 0.04%, nopinene 0.04%, citrene 0.03%, amphene 0.02% account for 97.08% of essential oil total amount altogether; The oil yield of broad-leaved camphor leaf essential oil is 0.57%, contain 30 kinds of compositions altogether, its Main Ingredients and Appearance has 11 kinds: trans-methylisoeugenol 94.04%, methyl eugenol 1.35%, 1,8-cineole 0.65%, α-caryophyllene 0.17%, α-terpineol 0.16%, linalool 0.14%, citrene 0.11%, sabinene 0.03%, nopinene 0.02%, lauric acid 0.02%, pine tar-4-alcohol 0.04% account for 96.73% of essential oil total amount altogether.Then the cinnamomum septentrionale hand. mazz. leaf essential oil is sent into fractionating column, heat up with electric energy formula or steam boiler, adopt the vacuum fractionation method, remove atmospheric boiling point and be 230～238 ℃ safrole (safrole) and part low boiling composition, remainder is the active ingredient of natural fungicidal agent.The broad-leaved camphor leaf essential oil can be carried without the fractionating column essence directly as the natural fungicidal agent effective ingredient.Become natural fungicidal agent by following formulated then: 40 kilograms of the mildew-resistant effective ingredients of silver-colored wood or broad-leaved camphor leaf essential oil, be dissolved in 50～55 kilograms 95% concentration ethanol, mix miscible.Used container is stainless steel or pottery or glassware, operates in the environment of normal temperature (10-30 ℃) normal pressure (1 atmospheric pressure) and sanitation and hygiene.And then adding 5～10 kilograms propane diols or glycerine, the pH value of solution value 6-7 that mixes makes 100 kilograms of natural fungicidal agent products altogether.
Through the natural fungicidal agent that the present invention preparation obtains, technology is simple, and cost is low, safety non-toxic, and it is strong that antibacterial and sterilization are renderd a service, and consumption is few, and anti-mold effect is good, and the mildew-resistant holding time is long, and applied range obviously is better than the various chemical anti mildew agents of existing use.
Claims (2)
1, a kind of compound method of natural fungicidal agent, it is characterized in that the bright leaf of silver-colored wood or broad-leaved camphor tree places shady and cool ventilation ground and divide, after becoming leather hard, the bright leaf of silver-colored wood or the broad-leaved camphor tree steam gas of packing into is carried in the distillation still of equipment and being distilled, when water temperature rises to 100 ℃ in the still, discharge in the curved tube mouth on steam kettle cover top, after the cooling, the plants essential oil liquefy of steam and steam state also oozes from the end of condenser pipe, leave standstill 12-24 hour after, form oil-water interfaces, with oil water separator plants essential oil and moisture are left, plants essential oil is dissolved in 95% concentration ethanol then, adds propane diols or glycerine again, the pH value of solution value after mixing is 6-7.
