Description

Technology Field

[0001] The present invention relates to a composition for extending the lifespan of cut flowers comprising an antimicrobial plant extract, a combustion product of organic matter, and propolis. Background Technology

[0002] Cut flowers are flowers or flower buds cut from plants along with their stems and leaves, and various flowers such as roses, chrysanthemums, carnations, lilies, hydrangeas, and peonies are used as cut flowers.

[0003] However, when the flower is removed from the plant, it is separated from the roots that absorb water and nutrients, so it wilts quickly after a few days and consequently loses its function as an ornamental plant.

[0004] There are various methods to extend the lifespan of cut flowers, such as disinfecting with bleach to eliminate bacteria in storage containers like vases, frequently cutting the lower part of the stems at an angle so that they can absorb water, adding plant nutrients containing sugar or sodium hypochlorite to the water to lower acidity, or physical methods such as keeping them away from fans and air conditioners that generate artificial wind.

[0005] The most effective method among the above methods is to eliminate bacteria inside the vase, but it has the disadvantage of requiring the vase to be disinfected continuously and potentially being harmful to the human body if chemical components such as bleach are handled without safety precautions.

[0006] Therefore, there is a need to invent a composition for extending the lifespan of cut flowers that is eco-friendly and provides convenience. Prior art literature

[0072] [Preparation Example 1] Preparation of contaminating microorganisms

[0073] Contaminating microorganisms for measuring antimicrobial activity are prepared as follows.

[0074] i) Staphylococcus aureus ( Staphylococcus aureus )

[0075] ii) Gray mold ( Botryis conerea )

[0076] i) Staphylococcus aureus is prepared by inoculating the strain into Luria-Bertani broth medium and culturing it at 30–37°C for 24 hours, and ii) gray mold is prepared by inoculating it onto Potato dextrose agar (MBcell) agar plates and culturing it at 25°C for 3 days.

[0078] [Experimental Example]

[0079] [Experimental Example 1] Evaluation of antibacterial activity against Staphylococcus aureus

[0080] To evaluate the antimicrobial activity against contaminating microorganisms, test substances are prepared as follows. The natural antimicrobial composition used in this experiment was prepared by mixing ginkgo extract and propolis in a 1:1 ratio.

[0082] Lacquer (lacquer tree extract) (ml) Ginkgo extract (ml) Propolis (ml) Charcoal powder (g) Composition 1 10 1.0 1.0 1.5 Composition 2 10 1.25 1.25 1.5 Composition 3 10 1.5 1.5 2.0 Composition 4 10 2.0 2.0 1.0

[0084] After inoculating 200 µl (microliter) of each test substance into the Staphylococcus aureus culture solution prepared in Preparation Example 1 and culturing for 24 hours, the antibacterial activity was confirmed by verifying the growth inhibitory effect. Mannitol Salt Agar (MSA, Difco) was used as the agar plate to verify the growth inhibitory effect, and the results are shown in Table 2 below.

[0086] Charcoal powder (g) Ginkgo extract (ml) Propolis (ml) Lacquer (lacquer tree extract) (ml) 0H viable cell count (CFU / ml) Viable cell count (CFU / ml) after 24 hours Experimental Example 1a 1.5 1.0 1.0 10 2.9 x 10^6 9.0 x 10 3 Experimental Example 1b 1.5 1.25 1.25 10 3.0 x 10^6 1.5x10 4 Experimental Example 1c 2.0 1.5 1.5 10 3.3 x 10^6 1.9x10 7 Experimental Example 1d 1.0 2.0 2.0 10 9.4 x 10^6 4.2x10 3

[0088] In the case of Experimental Example 1a, the number of viable cells in the culture medium after treatment with the test substance was 2.9 x 10 6 9.0 x 10⁶ at CFU / ml 3 It can be confirmed that the antibacterial activity is excellent, as it is reduced to about 1 / 1000 in CFU / ml.

[0089] In the case of Experimental Example 1b, the number of viable cells in the culture medium after treatment with the test substance was 3.0 x 10 6 1.5 x 10⁶ at CFU / ml 4It can be confirmed that the antibacterial activity is somewhat superior, as it is reduced to about 1 / 100 in CFU / ml.

[0090] In the case of Experimental Example 1c, the number of viable cells in the culture medium after treatment with the test substance was 3.3 x 10 6 1.9 x 10⁶ at CFU / ml 7 It can be confirmed that there is no antibacterial activity as it increases by about 10 times to CFU / ml.

[0091] In the case of Experimental Example 1d, the number of viable cells in the culture medium after treatment with the test substance was 9.4 x 10 6 4.2 x 10⁶ at CFU / ml 3 It can be confirmed that the antibacterial activity is excellent, as it is reduced to about 1 / 1000 in CFU / ml.

[0092] Through the results of Table 2, it was confirmed that the antibacterial activity against Staphylococcus aureus is excellent when the content of charcoal powder is less than 20% of the content of lacquer, and the content of the natural antibacterial composition is higher than that of charcoal powder.

[0094] [Experimental Example 2] Evaluation of Antimicrobial Activity Against Gray Mold

[0095] Using the dual culture assay method, 8 mm sections extracted from the gray mold culture solution prepared in Example 2 were inoculated onto PDA plates in triplicate, and 200 µl (microliter) of each test substance from Table 1 was inoculated. The plates were then cultured for 5 days, and the inhibition rate was confirmed by measuring the length of mycelial growth. The results are shown in Table 3 below.

[0097] Charcoal (g) Ginkgo extract (ml) Propolis (ml) Lacquer (lacquer tree extract) (ml) Mycelial growth inhibitory ability (%) Experimental Example 2a 1.5 1.0 1.0 10 42.3 Experimental Example 2b 1.5 1.25 1.25 10 32.1 Experimental Example 2c 2.0 1.5 1.5 10 41.0 Experimental Example 2d 1.0 2.0 2.0 10 41.0

[0098] In Experimental Example 2b, the mycelial growth inhibition ability was confirmed to be approximately 32.1%, and in Experimental Examples 2a, 2c, and 2d, results exceeding 41% were confirmed, confirming that the composition of the present invention effectively inhibits the growth of gray mold and has excellent antibacterial activity.
