Abstract
The present invention relates to a pyrethrin product with light stability and oxidative stability, which is characterized in that rosemary extract of which the content is 0.2 to 10% of that of pyrethrin is added in the original drug, the emulsion and the powder of the pyrethrum to be fully and uniformly mixed, and the pyrethrin product with light stability and oxidative stability (comprising the original drugs and preparations) are prepared. The rosemary extract used by the present invention is extracted from natural plant rosemary without toxic or side effect on a human body, and is extensively used for the fields of foodstuffs, medicinal health-care products, cosmetics, etc. The present invention avoids various kinds of damage caused by using a stabilizing agent of artificial synthesis to the human body, and effectively solves the difficult problems of the photolysis and the oxidative decomposition of natural pyrethrum.
Description
Technical field
Stable and the oxidation-stabilized pyrethrin product of light that the rosemary extract (rosemary extracts) that the present invention relates to a kind of pure natural is made as photostabilizer and antioxidant.
Background technology
The light stability of natural pyrethrum and oxidative stability are a difficult problem in the world.The past people adopt always is BHA, BHT, TBHQ of synthetic etc., the chemicals mass-energy of these synthetic plays certain effect, but also brought certain side effect simultaneously, the human liver kidney there is irreversible injury, for example: the experiment of Japan finds that BHA has carcinogenesis to the rat glandular stomach, France's scholar's research finds that the long-term edible food that contains BHT can cause the liver enlargement, so limited the quantity of or ban use of harmful synthetic stablizer in developed countries such as Japan, the U.S..Therefore seek a kind of safer, more effective pure natural stablizer and just become a emphasis in the present pyrethrum development field.
Summary of the invention
The purpose of this invention is to provide a kind of stable and oxidation-stabilized pyrethrin product (comprising former medicine and preparation) of light that is prepared into pure natural rosemary plant extract.
Technical scheme of the present invention is: adopt rosemary extract as photostabilizer in the pyrethrin product and antioxidant.The main component of rosemary extract is Salvin (claiming rosmarinic acid CarnosicAcid again) and carnosol (Carnosol), efficiently solves the light stability of natural pyrethrum and the difficult problem of oxidative stability.
Concrete application method is:
In natural pyrethrosin primary medicine or various preparation (as natural pyrethrin missible oil preparation, natural pyrethrum wettable powder etc.), 0.2～10% the rosemary extract that adds the pyrethrosin primary medicine effective component content, fully mix, make the pyrethrosin primary medicine and the various pyrethrin preparation of anti-photolysis and anti-oxidant decomposition.
What the present invention had overcome natural pyrethrum sees problems such as photolysis and oxygenolysis, add rosemary extract after, the pyrethrin antioxidant effect is BHA and BHT 2～4 times, is BHA and BHT 2 times to the effect of the anti-photolysis of pyrethrin.Rosemary extract is a pure natural substance, is widely used in food, makeup and Medicines and Health Product field, thereby has more improved the environment protecting of product.Generally speaking, adopt rosemary extract to make the stability problem that photostabilizer and oxidation stabilizer can solve pyrethrin, make pyrethrin extensively use with land for growing field crops and Organic food production process in the anti-smelting of insect pest.
Embodiment
Embodiment 1
Add 0.2% rosemary extract (currently available products) of pyrethrin active constituent content in natural pyrethrosin primary medicine, thorough mixing is even, makes anti-oxidant decomposition and the anti-pyrethrosin primary medicine of seeing photolysis.
Embodiment 2
When the preparing natural pyrethrin emulsion preparation, 5% rosemary extract that adds the pyrethrin active constituent content, add pyrethrin active constituent content 1 5% tangerine oil (Tangerine Oil) (main component is a limonene) again, evenly make anti-oxidant decomposition and the anti-natural pyrethrin missible oil preparation of seeing photolysis that contains pyrethrin effective constituent 0.5～5% with the turps diluted mixture again.
Embodiment 3
When preparing natural pyrethrin wettable powder, 10% rosemary extract that adds the pyrethrin active constituent content, mix, add pyrethrin active constituent content 10% dispersion agent (name of product is an emulsifying agent 5202) and 10% wetting agent (alkyl benzene sulphonate (ABS) ammonium) again, the tangerine oil that adds pyrethrin active constituent content 3% again, (diatomite: lime carbonate=8: 2) making the pyrethrin active constituent content is 0.5～1.5% anti-oxidant decomposition and the anti-natural pyrethrum wettable powder of seeing photolysis to add at last an amount of filler again.
