The invention discloses a bacillus megaterium Q7 for promoting the growth of leucaena leucocephala and improving the abundance of a probiotic microbial population. The bacillus megaterium Q7 is a bacillus megaterium for promoting the growth of leucaena leucocephala. Belongs to the technical field of microorganisms. The bacillus megatherium Q7 provided by the invention improves the conversion from total-effect nutrients to effective nutrients, and enhances the consumption of the leucaena leucocephala on soil nutrients, thereby achieving the effect of promoting the growth of the leucaena leucocephala. After the bacillus megatherium Q7 provided by the invention is applied, the enzyme activity of soil is remarkably improved, the conversion of available nutrients in the soil is remarkably enhanced, and the nutrient consumption capacity of leucaena leucocephala is enhanced. The bacillus megaterium Q7 is applied to promote the growth and development of the leucaena leucocephala, so that the contents of soil hydrolytic nitrogen and available phosphorus are remarkably increased, and the conversion to soil nutrients is enhanced. In the genus level, the average relative abundance of bacillus treated by the bacillus atrophaeus Q7 is increased to 9.97% from 1.33%, the bacillus pseudobecomes the leucaena leucocephala soil community dominant bacteria genus, and the relative abundance of Fictibacillus is increased by about 6 times, which indicates that the inoculation of the strain Q7 enables the leucaena leucocephala soil community structure to be changed, and the leucaena leucocephala soil community dominant bacteria genus is changed. And the increase of the relative abundance of dominant bacteria is promoted. Wherein the bacillus and the Fictibacillus belong to obvious increase of relative abundance and are possibly an important factor for promoting plant growth.

The invention discloses a leucaena leucocephala-sourced dihydrochalcone compound, a preparation method thereof and application of the dihydrochalcone compound as a tyrosinase inhibitor. According to the invention, the tyrosinase inhibitor dihydrochalcone compound (+ / -)-4, 4 '-Methoxy-3, 3', beta-trihydroxydihydroxychalcone is extracted and separated from the leucaena leucocephala plant, the structural formula of the compound is as shown in the formula (I), the plant material is rich in source and is a renewable tissue part, and not only is the economic benefit good, but also the environment-friendly effect is achieved. Pharmacological experiments show that the tyrosinase inhibitory activity of the compound (+ / -)-4, 4 '-Methoxy-3, 3', beta-trihydroxydihydroxycholone is stronger than that of kojic acid, and the compound (+ / -)-4, 4 '-Methoxy-3, 3', beta-trihydroxydihydroxycholone) is expected to be further developed into a new whitening cosmetic synergist, a drug for treating pigmentation dermatosis, an insect control agent or a food preservative and the like, and has a good prospect.

The invention discloses a preparation method of lactam alkaloid self-leucaena leucocephala and an application of the lactam alkaloid self-leucaena leucocephala in preparation of The antitumor active substance Cytochalasin J with high potential activity is extracted, separated and prepared from a leucaena leucocephala plant pod material, the leucaena leucocephala plant material is rich in source, extraction and preparation are easy to operate, and pharmacological experiments show that the compound Cytochalasin J has remarkable activity of inhibiting growth of central nervous system tumor cells SF-268 and breast cancer cells MCF-7 in vitro, and can be used for preparing antitumor drugs. Moreover, the monomeric compound is stable and easy to store, so that the compound has the potential of being developed and used for preparing corresponding anti-tumor drugs, or has the potential of application and development as a lead compound for developing effective low-toxicity anti-tumor drugs. Formula (1).
