Method for preparing natural plant deodorant

Abstract

The invention discloses a method for preparing a natural plant deodorant. The method comprises the following steps: irradiating picked plant leaves by using microwaves with power of between 20 and 60 W / g and drying the irradiated leaves in the shade, wherein the laying thickness of the leaves is between 5 and 30 millimeters; microwave frequency is 2,450 MHz; and irradiation time is between 1 and 3 minutes; smashing the dried leaves, extracting the smashed leaves by using 20 to 80 mass percent aqueous solution of ethanol and combining filtrate extracted every time to obtain extracting solution, wherein the mass ratio of the leaves to the aqueous solution of ethanol is 1:6-10; the extraction temperature is between 50 and 80 DEG C; extraction time is about 10 to 60 minutes; and the raw materials are extracted for 2 to 3 times; performing concentration on the extracting solution under reduced pressure until ethanol cannot be detected, filtering the extracting solution and removing impurities in the filtrate by macroporous adsorption resin column chromatography, wherein the macroporous adsorption resin column chromatography process of the filtrate comprises the following steps: elutingthe filtrate with water until effluent liquid becomes pale yellow, eluting the filtrate with 40 to 80 mass percent ethanol, detecting eluent by a hydrochloric acid-magnesium powder method, and collecting the eluent when flavone is detected until no flavone is detected; and performing concentration on the collected eluent under reduced pressure to recycle the ethanol and preparing into dry power to obtain dry powder of the natural plant deodorant. The method has the advantages of low production cost, simple process, no pollution, good effect and convenient and flexible use.

Description

A kind of preparation method of natural plant deodorant technical field The invention belongs to a method for preparing a plant deodorant, in particular to a method for extracting a deodorant from natural plant leaves such as paulownia leaves, poplar leaves, willow leaves, pagoda tree leaves and creeper leaves. Background technique Odor pollution has been widely paid attention to by countries all over the world, and is considered by many countries as one of the six major public hazards next to noise. Malodorous substances refer to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment. The chemical substances emitting foul smell mainly include hydrogen sulfide, mercaptans, sulfides, ammonia, amines, noise-inducing compounds, nitro compounds, hydrocarbons, aldehydes, fatty acids, alcohols, phenols, ketones, Vinegars and organic halogen derivatives, etc. Among the odorous substances that are more harmfu...

Problems solved by technology

This method is more suitable for places with a centralized supply and exhaust system. For places without such conditions, centralized exhaust equipment needs to be added, which requires a large investment, increases noise, and the adsorption material needs to be replaced frequently.

(3) Ozone oxidation method: Intensify the air by various methods (such as light-contact coal) to generate O3, oxidize the odorous pollutants in the place, and also have a bactericidal effect, but the biggest defect of this method is that the ozone concentration is not easy to control. obvious harm to human health

But there is no report to the utilization of these plant leaves, especially there is no report of utilizing it to prepare natural plant deodorant
