Embodiment 1

[0025] A kind of cornus fruit pit wood vinegar with antibacterial effect, it is prepared by following method:

[0026] (1) Take the natural air-dried dogwood fruit core, crush it through a 40-mesh sieve, put it into the retort, use a vacuum pump to pump out the air in the retort, and then inject nitrogen until the air pressure is balanced; the heating program is set as follows: the heating rate is 20°C / min, the target temperature is 500°C, and the holding time is 30min. Cooling water is introduced into the condensing device, the wood gas outlet pipe is opened, and the initial temperature is recorded when the liquid begins to distill out. The fraction is collected every 100°C (300~ 500°C), to obtain stock solutions of wood vinegar with different distillation temperatures.

[0027] (2) Take the stock solution of wood vinegar obtained in step (1) and put it into a brown glass bottle, and let it stand at 4°C for 30 days; when the stock solution of wood vinegar is divided into upp...

Abstract

The invention discloses dogwood kernel wood vinegar and application thereof. According to the method, waste cornus officinalis kernels in the cornus officinalis medicinal material harvesting and processing process are used as raw materials, and the cornus officinalis kernel wood vinegar is prepared by adopting a pyrolysis carbonization technology. Results of inhibition zone and minimum inhibitory concentration experiments show that the wood vinegar can significantly inhibit the growth of escherichia coli, shigella dysenteriae and staphylococcus aureus, and has a good bacteriostatic effect. The invention relates to an optimal preparation process of dogwood kernel wood vinegar based on antibacterial activity screening. Therefore, the dogwood kernel wood vinegar is expected to be developed into natural antibacterial lotion or disinfectant, meanwhile, a way can be provided for waste utilization in the dogwood medicinal material processing process, waste is turned into wealth, and the economic chain of the dogwood industry is extended.
