preparation example Construction

[0048] The preparation method of the ginseng extract may include: grinding any one selected from ginseng leaves, ginseng whiskers, ginseng taproots, and combinations thereof to prepare ground ginseng (grinding); mixing the ground ginseng with distilled water and adding the The resulting mixture is sterilized (sterilization); air-cooling the sterilized mixture; and drying the mixture and extracting the dried mixture with a solvent (extraction); and the preparation of the green tea extract may include: grinding Green tea to prepare ground green tea (grinding); mixing the ground green tea with distilled water and sterilizing the resulting mixture (sterilization); air cooling the sterilized mixture; and drying the mixture and extracting it with a solvent Dry mixture (extraction).

[0049] Any grinding device may be used as long as it is capable of grinding ginseng leaves, ginseng silk, ginseng taproot or green tea, and the device is, for example, a homogenizer. The size of the gr...

Embodiment

[0084] Hereinafter, the present invention will be described in detail with reference to specific embodiments so that the present invention can be easily implemented by those skilled in the art. However, the present invention can be implemented in various forms and is not limited to the embodiments described herein.

[0085]

[0086] (1) Preparation of the active ingredient extract of ginseng

[0087] Ginseng silk and ginseng leaves were ground using a homogenizer to prepare a ground ginseng product (grinding). 30 g of ground ginseng was mixed with 600 ml of distilled water to prepare a mixture, and the mixture was sterilized at 121° C. for 15 minutes using an autoclave (sterilization). The sterilized mixture was cooled in air. The air-cooled mixture was dried, and 600 g of the ground powder was incorporated into 6 L of methanol and stirred, and extracted 3 times in a bowl for 3 hours, followed by filtration, to prepare a ginseng extract (extraction). The ginseng extract ...

[0127] * "-" in Table 4 means that the antimicrobial effect was not determined.

[0128] It can be seen from the above table 3 that after 24 hours of reaction, when ginseng extract was used alone, 100% of Escherichia coli was removed, and when ginseng extract and green tea extract were mixed at 90:10, 80:20 and 66:34 99.99%, 99.99%, and 99.97% of E. coli were removed, respectively. In the case of all mixing ratios, 100% of Staphylococcus aureus was removed after 3 hours ...

Abstract

Discloses an synergistic antimicrobial composition containing a ginseng extract and a green tea extract in a weight ratio from 6:4 to 7:3 and an antimicrobial filter containing said composition and a method for manufacturing them. Said single filter exhibits higher antimicrobial and antiviral efficiency, has little pressure loss and could be produced at lower cost as compared with two systems containing two filters with single antimicrobial agent.

Description

technical field [0001] The present invention relates to an antimicrobial composition comprising ginseng extract and green tea extract, an antimicrobial filter and a manufacturing method thereof. Background technique [0002] In response to the recent increase in environmental concerns and thus the increased demand for indoor air purification, various air conditioning devices for removing foreign substances and microorganisms from the air have been developed. [0003] Filters are used in such air conditioning devices. Depending on the type, size and characteristics of the objects to be removed, these filters require a variety of forms and capabilities. Therefore, various filters suitable for these requirements have been developed. [0004] When such a filter is endowed with antimicrobial activity, the filter can sufficiently remove or destroy microorganisms such as bacteria, viruses, and fungi in the air, thereby obtaining a satisfactory air conditioning effect and an excel...
