Plant extract composition with bactericidal effect and use of the same

Abstract

A plant extract compound with antibacterial effect and its uses are described. It is mainly made from the ethanol ultrasonic extracts of ginger, wild ginger flower, mountain pepper, galangal, tea and coffee beans. The compound has been tested and found to have a good inhibitory effect on Propionibacterium acnes.

Claims

1. A plant extract compound with bactericidal effect is prepared by the following steps: The following raw materials are used: ginger rhizome, wild ginger flower with stem, mountain pepper fruit, galangal rhizome, Jin Xuan tea leaves, and Arabica coffee beans. The ginger, mountain pepper, galangal, and tea leaves are sliced ​​and individually mixed with 50-70% ethanol (by volume). The wild ginger flower is dried, pulverized, and also mixed with 50-70% ethanol. The 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. The ultrasonic frequency is set to 28000Hz±8000Hz during extraction. 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 0.5%.

2. A plant-based compound composition with bactericidal effect as described in claim 1, wherein, The ultrasonic extraction time is 90 minutes each time, and each raw material is extracted 3 times.

3. A plant-based compound composition with bactericidal effect as described in claim 1, wherein, The volume percentage concentration of all six raw material diluents in the finished product was adjusted to 0.25%.

4. Use of a plant extract compound composition with bactericidal effect as described in claim 1 or 3, for the purpose of inhibiting Propionibacterium acnes.
