The invention discloses laurel essential oil with anti-aging activity and application of the laurel essential oil. According to the method, laurel essential oil is used for acting on caenorhabditis elegans to verify the aging delaying effect of the caenorhabditis elegans, after the caenorhabditis elegans are counted and subjected to synchronization treatment, a life determination test of the caenorhabditis elegans is carried out, a blank control group, a DMSO solvent group, a positive drug group and a laurel essential oil experimental group are set respectively, a survival curve is drawn, and statistical analysis is carried out. Results show that the lifetime of nematodes in a laurel essential oil treatment group is remarkably prolonged, and the anti-aging effect of the laurel essential oil treatment group is superior to that of a Meanwhile, target function analysis on the laurel essential oil shows that the essential oil regulates and controls senescence-related pathways. The further determination of the effect of monomer components in the laurel essential oil on delaying caenorhabditis elegans aging shows that p-cymene, methyleugenol, ocimene, linalool, sabinene, 4-terpene alcohol, terpinene and linalyl acetate show significant anti-aging activity.

The application provides application of pig's tooth saponin volatile oil in preparation of a medicine for treating cerebral ischemia-reperfusion injury, and a preparation method of the pig's tooth saponin volatile oil is as follows: pig's tooth saponin decoction pieces are taken, water and n-hexane are added, and volatile oil is obtained through steam distillation; the volatile oil is collected, anhydrous sulfuric acid is added, and water is removed; and the mixture is left overnight to obtain the pig's tooth saponin volatile oil. The prepared pig's tooth saponin volatile oil acts on key target points of VEGFA, SRC, MAPK8, PIK3CA and TNF through active ingredients of paeonol, linalool, methyl eugenol, anethole and eugenol, regulates multiple signal pathways of sphingolipids, TNF and VEGF, inhibits cell oxidative stress injury, inhibits release of inflammatory factors and regulates nerve function, so as to play a role in treating cerebral ischemia-reperfusion injury, and lay a foundation for further in-depth study on a treatment mechanism of pig's tooth saponin in treating 'opening the orifices and connecting the heart and the lung'.

The application discloses a kind of active substances for crop protection and its composition and preparation method and application, the substance general formula as follows: Wherein: R1 It is hydrogen atom, halogen, cyano, methyl, methoxy, nitro, trifluoromethyl or the disubstituted of arbitrary combination of above halogen;R2 It is hydrogen atom, halogen or nitro substitution.This application derivative shows better inhibitory effect to rice bacterial leaf spot, rice bacterial leaf blight, kiwi bacterial canker, citrus canker.The inhibitory activity of compound II-18 to kiwi bacterial canker bacteria is best.Plant pathogenic fungi (sclerotinia sclerotiorum, phomopsis viticola, botryosphaeria dothidea and fusarium graminearum) inhibitory activity test shows that compound II-10 shows better inhibitory activity to fusarium graminearum.In addition, part of the derivatives of the application has significant contact toxicity to bactrocera dorsalis (Hendel).The composition of compound II-5 and methyl eugenol shows synergistic trapping effect in the process of preventing and treating the main pest of kiwi, bactrocera dorsalis (Hendel).

The invention relates to a tobacco flavor with a sweet flower fragrance style, a flavor adsorption material and application of the flavor adsorption material in cigarettes. The tobacco flavor is prepared from cananga odorata essential oil, alpha-jinitol, eucalyptus alcohol, alpha-cananga odorata oleene, geraniol, methyleugenol, vanillin and anisyl acetate. The cananga odorata essential oil and seven specific spice components are creatively combined to form the mixed spice, compared with single cananga odorata essential oil, all the components in the mixed spice are matched and synergistic, sweet flower fragrance can be provided when cigarettes are smoked, the fruit fragrance and sweet fragrance of the cigarettes are obviously improved, the fragrance harmony is good, and the cigarette flavor is good. The smoke characteristic of the cigarette is improved; and after the perfume is used for slow release treatment, the stability of the sweet flower fragrance flavor can be maintained during cigarette smoking, and the flavor of the perfume cannot be changed due to the change of the original proportion of the components in the slow release process, so that the stability of sensory expression is realized, and the sensory quality of tobacco products is comprehensively improved.

The application provides a bethyla huidobrensis bisexual attractant, a preparation method and application thereof. The bethyla huidobrensis bisexual attractant comprises methyl eugenol and isoamyl acetate. The attractant significantly improves the attraction effect on male and female bethyla huidobrensis, reduces the use amount of methyl eugenol, has the advantages of low cost and simple preparation, and is suitable for industrialized production of the bethyla huidobrensis killing agent.

Provided is the use of olfactory receptor BdorOR94bl as a target in the control of Bactrocera dorsalis. By means of functional genomics, electrophysiology, behavioristics, and traditional chemical ecology, the role of methyl eugenol in the mating behavior of Bactrocera dorsalis and the key olfactory receptor for male flies to recognize methyl eugenol are comprehensively analyzed. For the first time, the key olfactory receptor BdorOR94bl of Bactrocera dorsalis for recognizing methyl eugenol is identified, and the genomic coding region sequence and transcribed amino acid sequence information of the key olfactory receptor BdorOR94bl is obtained, which not only lays an important foundation for the subsequent screening of more stable and efficient structural analogs by taking the gene as a target, but also provides a foundation for the development of nucleic acid pesticides.

The application relates to a method for preventing and treating termites in a poria cocos planting process. The method comprises the following steps: spreading a termite poison bait composition in a cellar in a poria cocos planting area after excavation and sunning; digging a trench around the periphery of the poria cocos planting area, covering the trench with soil after spreading the termite poison bait composition, wherein the termite poison bait composition comprises methyl eugenol, azadirachtin and carvone, and a termite prevention and treatment buffer isolation belt is established; and placing a pine wood section in the cellar, covering the pine wood section with soil after inoculating poria cocos spores on a top sawing opening of the pine wood section. The scheme provided by the application can effectively prevent and treat termites in the poria cocos planting process and has no pesticide residue.
