Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of spirostane-3-glycoside glycolipids, which are novel and effective preservatives for cosmetics, detergents and food preparations of natural origin. [Background technology]
[0002] The increase in resistant microorganisms indicates a need for compounds that can prevent microbial infection and contamination while exhibiting low toxicity to humans. Some triterpene glycosides exhibit antimicrobial properties. Treatment with membrane-disrupting agents is commonly observed in microorganisms, leading to cellular apoptosis. Therefore, triterpene glycosides are expected to be used as antimicrobial agents due to their high biological activity and low toxicity against microorganisms.
[0003] Spirostane glycosides are particularly useful as food preservatives, but also in other everyday products, such as pet food and cosmetics. Preservation methods such as pasteurization and the addition of chemical preservatives like sorbic acid and benzoic acid can significantly affect the sensory properties of a product. However, the sensory changes associated with preservation are undesirable because consumers value natural flavors. Furthermore, the high environmental costs of the precursor compounds used in industrial production mean that alternatives to synthetically produced preservatives are needed. Glycolipids, with their antimicrobial properties, low toxicity, and more environmentally friendly production, offer a suitable alternative to widely used preservation methods.
[0004] US Patent No. 5,999,623 discloses ustilaginous acid and its esters for combating specific bacteria such as Alicyclobacillus acidoterrestris, Penicillium expansum, Gluconacetobacter liquefaciens, Lactiplantibacillus plantarum, Zygosaccharomyces ruxi, Aspergillus braziliensis, Brettanomyces nardanensis, and Weissella confusa in non-alcoholic beverages. The steroidal saponin Parissaponin VII (Structure A) is well known from the rhizomes of the plant Paris polyphylla (Rhizoma Paridis Chonglou). Its antitumor and antifungal activities have been described in the literature (Non-Patent Documents 1 and 2). Surprisingly, its antimicrobial activity is known only against Propionibacterium acuminum. Spirostane glycoside B is known from several Hosta species and has been described for its antitumor and antifungal, but not antimicrobial, activity (Non-patent Documents 4 and 5).

[0020] food preparations A food composition according to the invention is any preparation or composition suitable for ingestion and used for nutritional or recreational purposes, comprising a composition according to the invention, and is generally a product intended to be introduced into the oral cavity of a human or animal, to remain there for a certain period of time and then either eaten (e.g., a cooked food or feed, see also below) or removed from the oral cavity again (e.g., chewing gum). Such products include any substance or product intended for human or animal consumption in its processed, partially processed, or raw state, and also includes substances added to ingestible products during their manufacture, preparation, or processing and intended to be introduced into the oral cavity of a human or animal.
[0021] Food compositions according to the present invention also include substances that are swallowed by humans or animals in an unchanged, processed, or prepared state and subsequently digested. In this respect, orally ingestible products according to the present invention also include casings, coatings, or other encapsulations that are or are expected to be swallowed at the same time. The term "orally ingestible products" encompasses ready-to-eat foods and feeds, i.e., foods or feeds that are already complete with respect to substances important for taste. The terms "ready-to-eat foods" and "ready-to-eat feeds" also include solid or semi-solid ready-to-eat foods or feeds.

[0042] Preferred embodiments are cosmetics, detergents and food preparations comprising the preservative composition according to the invention.
[0043] The present invention also provides the use of the preservative composition according to the invention for the antimicrobial stabilization of cosmetics, detergents or food preparations, excluding beverages.
[0044] It is emphasized that, for the sake of good order, all preferred embodiments mentioned above, in particular with regard to combinations, ratios and amounts, also apply to the claimed methods and uses, so that their repetition is not necessary. [Example]
[0045] Manufacturing example Example 1: Isolation of spirostane glycosides A) Extraction, isolation, and identification of compounds of formula A-D 1.0 kg of dried plant material was extracted with 12.5 L of methanol-MTB-ether (50:50 v / v) and methanol (100%) for 24 hours at room temperature. Both extracts were combined and the solvent was evaporated in vacuo. The extraction yield depends on the plant species and plant part used. Typically, the extraction yield is about 5% to 30% of the dried plant material. B) Pre-fractionation by reversed-phase chromatography
[0046] The raw extract was subjected to reversed-phase medium-pressure chromatography (RP-MPLC) to enrich the target compounds. Reversed-phase MPLC is highly efficient at removing secondary metabolites such as sugars, lipids, and flavonoids, allowing for enrichment of the target compounds. It makes sense to combine different MPLC pre-fractionation methods to more specifically enrich selected saponins, for example, by combining RP18 and RP4.
[0047] C) Second purification step by reversed-phase chromatography Pure compounds were isolated by reverse-phase chromatography using different fractions from the initial separation step by MPLC. In some cases, several repeated separations by HPLC were required to reach a purity of greater than 90% per compound. Promising fractions from the preparative HPLC run, detected by light scattering detection ELSD, were analyzed by LCMS. The solvent of all fractions containing the desired compounds was removed in vacuo, followed by a lyophilization step. The isolated compounds were characterized by LCMS and 1D and 2D NMR spectroscopy. D) Isolated compounds [Table B1] [Table B2]
[0048] Example 2: Antimicrobial Activity Compounds are dissolved at a concentration of 20 mg / mL in 100% DMSO. Pre-culture: Yeast and bacteria are plated on potato dextrose agar, resuspended in potato dextrose broth, and CFU determined by OD measurement. CFU of PDB strains is adjusted to pH 3.8. Preculture: Spores of mycelium-forming fungi were used directly after thawing frozen stocks of known titers. Final titer used in the assay: 5 x 10 yeast strains 3 CFU / ml, bacteria 1*10 6 CFU / ml, fungus (spores) 5*10 4 CFU / ml Potato dextrose broth pH 3.8 was used as the assay matrix. 500 ppm (0.05%) of the compound was screened (final DMSO 2.5% (v / v)) Volume: 100µl in 96-well format Positive controls: potassium sorbate, sodium benzoate, triclosan 28°C to 30°C, static incubation The incubation period varies from 2 to 8 days depending on the type of spoilage bacteria. Visual assessment (one eye at a time, with binoculars for fungi) The antimicrobial activities are shown in Table 1. Table 1: Antimicrobial activity of tested compounds (Minimum inhibitory concentration (MIC), μg / ml) [Table 1A] [Table 1B]
[0049] The examples clearly show that the spirostane glycosides according to the invention exhibit significant activity against a wide range of microorganisms that can typically be found in everyday products such as food, pet food, or cosmetics. The performance of the spirostane glycosides according to the invention is comparable to that of the common natural preservatives sorbic acid and benzoic acid, and can be synergistically enhanced by blending two or more of the terpene glycosides according to the invention, or by using a blend of the glycolipids with a secondary preservative such as sorbic acid, benzoic acid, lactic acid, ethanol, or PHB (esters).
