Abstract
Description
[Technical Field]
[0001] The present invention relates to a micelle composition containing a sugar-based surfactant, which can stably encapsulate a glycoside active ingredient and increase its cutaneous absorption, and a method for producing the same. [Background technology]
[0002] Conventional methods that simply use surfactants to improve the solubility of poorly soluble substances fail to enhance the pharmacological efficacy of the active ingredient, and even if micelles are formed, there is a risk of the encapsulated active ingredient leaking out. Therefore, polymer block copolymer micelles are widely used as active ingredient carriers. First, polymer block copolymer micelles have a much lower critical micelle concentration than low-molecular-weight surfactants, making them highly stable. Furthermore, the polymer chains provide a slow dissociation rate, allowing for continuous action. Furthermore, the method of encapsulating poorly soluble substances in micelles is simple, and they easily redisperse upon reconstitution, eliminating the need for additional additives during administration.
[0003] However, because polymeric micelles are made using synthetic polymers, they are not suitable for environmental social governance (ESG). Active glycoside ingredients are widely distributed in the plant kingdom, so they require a suitable, environmentally friendly, and safe carrier. Furthermore, while glycoside active ingredients are poorly soluble in water, they contain structurally hydrophilic sugars, which means that their particle size increases when encapsulated in polymeric micelles, making them unsuitable for encapsulation in polymeric micelles.
[0004] Therefore, there is a need to develop a carrier for encapsulating poorly water-soluble glycoside components, along with safe and sustainable raw materials and methods. [Prior art documents] [Patent documents]

[0112] The present invention will be described in more detail below with reference to examples. These examples are merely for the purpose of illustrating the present invention, and it will be obvious to those skilled in the art that the present invention is not limited to these examples.
[0113] [Example] 1. Preparation of naturally derived purified saponin Ginseng was prepared from roots of Panax Ginseng CA Meyer that were over 4 years old. Green tea was prepared from roots of the Yabukita variety of tea plant that were over 30 years old (purchased from Osulloc Farm).
[0114] 2 kg of ginseng or green tea was added to 4 L of water, water-in-methanol, or methanol, and reflux extraction was performed three times. The extract was then allowed to settle at 15°C for six days. The residue and filtrate were separated by cloth filtration and centrifugation. The filtrate was concentrated under reduced pressure to obtain an extract, which was suspended in water and then extracted five times with 1 L of ether to remove pigments. The aqueous layer was then extracted three times with 50 mL of 1-butanol. The entire 1-butanol layer was treated with 5% KOH, washed with distilled water, and then concentrated under reduced pressure to obtain the 1-butanol extract. This extract was dissolved in a small amount of methanol, added to a large amount of ethyl acetate, and the resulting precipitate was dried to yield 40–80 g of purified natural saponin extract.
[0115] 2. Preparation and evaluation of micellar compositions containing glycoside active ingredients First, the glycosides, purified ginseng saponin and purified green tea saponin (Figures 1 and 2), were prepared by dissolving them in ethanol or an aqueous ethanol solution, and each sugar-based surfactant was thoroughly hydrated in water. Here, purified ginseng saponin contains compound K as its main substance (Non-Patent Document 1), and purified green tea saponin contains Rogchaponin R12 as its main substance (Non-Patent Document 2).
[0116] The components are shown in Tables 1 and 2. The ethanol part was mixed with the water part, and the ethanol was completely evaporated using an evaporator (Hei-VAP Advantage ML / G3; Heidolph, Germany) to produce micelles, which were then visually evaluated for encapsulation.
[0117] Whether or not the substance was encapsulated in a micelle was evaluated based on whether or not transparency was maintained by visual inspection after production.
[0118] [Table 1]
[0119] [Table 2]
[0120] As a result of the experiment, it was confirmed that the active ingredient was stably encapsulated in the micelles in the Examples, as it was solubilized transparently. In contrast, in the Comparative Examples, it was confirmed that the active ingredient was not stably encapsulated in the micelles, as precipitation occurred (Figures 3 and 4).
[0121] 3. Preparation and evaluation of micellar compositions containing non-glycoside active ingredients First, the non-glycoside active ingredient, methylenedioxycinnamate (ACT Co., Ltd., South Korea), was thoroughly dissolved in THF or a THF aqueous solution, and each sugar-based surfactant was thoroughly hydrated in water. The components are listed in Table 3. The THF part was mixed with the water part, and the THF was completely evaporated using an evaporator to produce micelles, which were then visually evaluated for encapsulation.
[0122] Kojyl methylenedioxycinnamate has the chemical formula shown in Figure 5.
[0123] Whether or not the substance was encapsulated in a micelle was evaluated based on whether or not transparency was maintained by visual inspection after production.
[0124] [Table 3]
[0125] As a result of the experiment, it was confirmed that in the examples containing glycoside active ingredients, the active ingredients were solubilized transparently (Figure 3), but in the active ingredients that were not glycosides (Comparative Examples 6 to 8), precipitation occurred after production (Figure 6).
[0126] 4. Confirmation of the effect of adding citric acid or tannic acid on improving the stability of micellar compositions To confirm the effect of adding citric acid (Sigma-Aldrich, USA), tannic acid (Sigma-Aldrich, USA), and tocopherol (TAMA BIOCHEMICAL CO., LTD., Japan) to improve the strength of the micelle composition, the composition was prepared as shown in Table 4.
[0127] The ethanol portion was mixed with the water portion, and the ethanol was completely evaporated using an evaporator to produce micelles. The micelle composition was placed in a dialysis bag (Spectra / Por, Spectrum Laboratories, Inc., USA), and the release profile of compound K from distilled water (DW) was monitored over time. Compound K was quantified by high-performance liquid chromatography (HPLC; Waters, USA).
[0128] [Table 4]
[0129] The experimental results are shown in Figure 7. It was confirmed that the release of compound K was reduced in Examples 6 and 7 compared to Example 5. This indicates that the stability of the micelle composition was further improved when citric acid or tannic acid was added.
[0130] It was also confirmed that the stability of the micelle composition was further improved when tocopherol was added as in Example 8.
[0131] 5. Confirmation of the skin absorption improvement effect of micellar composition To confirm the improvement of skin permeation by the micelle composition, the composition was prepared as shown in Table 5. The micelle composition was also loaded into the donor chamber of a Franz diffusion cell system (Hanson Research, USA), and absorption was monitored over time.
[0132] The receptor chamber was filled with a PBS:ethanol mixture (9:1, v / v), and human skin (Biohead, South Korea) was fixed between the donor and receptor chambers.
[0133] [Table 5]
[0134] The experimental results are shown in Figure 8. Compared with Comparative Examples 1 and 2, it was confirmed that the absorption of compound K increased when the micelle compositions of the present invention (Examples 5 and 6) were used. Furthermore, it was confirmed that the absorption of compound K in Example 6 tended to be lower than that in Example 5, but there was no significant difference.
[0135] 6. Preparation of micelle composition and confirmation of encapsulation effect at various masses To confirm the preparation of micellar compositions and the encapsulation effect at each mass, the compositions were prepared as shown in Table 6. The ethanol part was mixed with the water part, and the ethanol was completely evaporated using an evaporator to prepare micelles, which were then visually inspected to determine whether or not they were encapsulated.
[0136] [Table 6]
[0137] When the mass ratio approached 1:1 as in Example 11, complete precipitation did not occur, but fine precipitates were observed during storage after production.
[0138] The micellar composition of the present invention was realized through experiments based on combinations selected through structure-based simulations. Because it has a mixed micelle morphology, it maintains stability despite having a higher loading than other micelles.
[0139] 7. Particle size measurement and morphology observation of micelle compositions For particle size measurement and morphology observation of the micelle composition, the composition of Example 8 was used to confirm the preparation and encapsulation effect at each mass.
[0140] The particle size was measured by DLS (Zetasizer, Malvern Instruments Ltd., UK), and the results are shown in Figure 9. The particle morphology was also measured by CryoTEM (Tecnai G2 Spirit TWIN FEI microscope, USA), and the approximate micelle size is shown in Figure 10.
