Description
Technical field
The present invention relates to a kind of plant insecticide, and in particular to a kind of plant insecticide and preparation method thereof and use
On the way.
Background technology
Insecticide is the medicine for preventing and treating agricultural pests and urban health insect, development and mankind's number due to agricultural
Amount increases to be doubled and redoubled to the demand of grain, and the use of insecticide is very universal, still, and nearly all insecticide all can be seriously
Change the ecosystem, most of harmful, others can be concentrated in food chain.
In fact, the whole world, which there are about 1000 various plants, has more or less virulence to insect.It is wide variety of to remove
Worm chrysanthemum, trifoliate jewelvine and tobacco etc..In addition similar juvenile hormone, precocene, moulting hormone active material are also contained in some plants.Such as
The camptothecine separated from the root skin of camplotheca acuminata, bark or fruit has very strong infertility effect to dendrolimus punctatus.Develop plant source
Insecticide not only plays wide material sources, while also having to more environment-friendly, adapts to agricultural sustainable development.
But plant insecticide generally has as a drawback that：
1. most natural products compound structures are complicated, it is too high not to be easily-synthesized or synthesize cost, is difficult large-scale production；
2. active component is easily decomposed, formulation ingredients are complicated, are difficult standardization；
3. most plants insecticide plays drug effect slowly, some friends peasant are caused to think that used insecticide does not have
Effect；
4. spray is often, the longevity of residure is short, is difficult to receive for peasant；
5. because the distribution of plant has region, more than the limiting factor being subject in the selection in processing place and plant
Collection has seasonality etc..
Isolarisiresinol ((+)-isolariciresinol), No. CAS：548-29-8, its physicochemical property is as follows：
Mp158~160 DEG C；114~115 DEG C (water-methanol), 20/D+64.6 ° of [α] (c=1.5, acetone).UVλmax(lgε)nm：222
(4.56), 285 (4.23), 290 (4.16).IRγmaxcm-1：3400,3300 (OH), 1600,1580.EI-MS m/z：360(M
+, 100).Molecular formula：C20H24O6, molecular weight：360.41.The existing researcher of effect of the isolarisiresinol in medicine enters
In row research, such as patent CN1704066A " medicinal usage of isolarisiresinol ", isolarisiresinol is used to treat
There is no in dead medicine caused by the MOFE that therefore endotoxemia and reduction induce, but in existing literature it is different fall
Application report of the leaf pine tree lipidol in plant insecticide is prepared.
