Plant extract composition and use of the same

Abstract

A plant extract composition and its uses are disclosed. The composition is mainly made from the ethanol ultrasonic extracts of ginger, wild ginger flower, mountain pepper and galangal. The composition has been tested and found to have a bacterial reduction rate of over 90% against sclerotium thunbergii, thus having the effect of inhibiting pet symptoms related to this fungus.

Claims

1. The use of a plant extract composition for inhibiting sclerotium thunbergii, the composition being prepared by the following steps: Using ginger rhizomes, wild ginger flower with stems, Litsea cubeba fruit, and Alpinia galanga rhizomes as raw materials; ginger, Litsea cubeba, and Alpinia galanga are sliced ​​and individually mixed with 50-70% ethanol; wild ginger flower is dried, pulverized, and also mixed with 50-70% ethanol, with a weight ratio of each raw material to ethanol of 1:10; The ethanol mixtures of the four raw materials are individually extracted using an ultrasonic extractor, with the ultrasonic frequency set to 28000Hz±8000Hz; The extracted ethanol mixtures are individually concentrated under low-temperature vacuum at a temperature of 45 degrees Celsius and a vacuum pressure of less than 80 mbar until the ethanol is completely boiled; the concentrated solutions of each raw material are then individually diluted with pure water, with a weight ratio of each concentrated solution to pure water of 1:5 to 1:

10. After dilution, the four raw material diluents are mixed with pure water to form a composition, and the volume percentage concentration of the four raw material diluents in the finished composition is 5%.

2. Use of the plant extract composition as described in claim 1, wherein, The ultrasonic extraction time is 90 minutes each time, and each raw material is extracted 3 times.

3. The use of a plant extract composition for inhibiting sclerotium thallus, the composition being prepared by the following steps: Using ginger rhizomes, wild ginger flower with stems, mountain pepper fruit, galangal rhizomes, Jin Xuan tea leaves, and Arabica coffee beans as raw materials; ginger, mountain pepper, galangal, and tea leaves are sliced ​​and individually mixed with 50-70% ethanol (by volume); wild ginger flower is dried and pulverized and also mixed with 50-70% ethanol; coffee beans are also pulverized and mixed with 50-70% ethanol. The weight ratio of the six raw materials to ethanol is 1:

10. The ethanol mixtures of the six raw materials are individually placed in an ultrasonic extractor for extraction, with the ultrasonic frequency set to 28000Hz±8000Hz. The extracted ethanol mixtures were individually concentrated under low-temperature vacuum at a temperature of 45 degrees Celsius and a vacuum pressure of less than 80 mbar. After the ethanol was completely boiled, each concentrate was individually diluted with pure water at a weight ratio of 1:5 to 1:

10. After dilution, the six diluted concentrates were then mixed with pure water to form a composite, and the volume percentage concentration of each of the six diluted concentrates in the final composite was 5%.

4. Use of the plant extract composition as described in claim 3, wherein, The ultrasonic extraction time is 90 minutes each time, and each raw material is extracted 3 times.

5. Use of the plant extract composition as described in claim 3, wherein, The volume percentage concentration of the six raw material diluents in the finished product was adjusted to 0.5% or 0.25%.
