Attached Figure Description

[0020] Figure 1 This is a flowchart illustrating the preparation process of a Tibetan medicine composition for sanitary napkins proposed in this invention. Detailed Implementation

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example 1: Preparation of Tibetan Medicine Composition Formula: 20 kg of sweet osmanthus, 25 kg of raspberry, 18 kg of spruce, and 10 kg of bright salt.

[0024] Preparation process: Pretreatment: The *Mesona chinensis*, *Rosa banksiae*, and *Picea spp.* were cleaned to remove impurities and dried in a 50℃ oven until the moisture content was below 8%. They were then pulverized using a universal pulverizer, passed through a 50-mesh sieve, and mixed evenly to obtain a mixed powder. The *Bright Salt* was pulverized using an ultrafine pulverizer, passed through a 120-mesh sieve, to obtain fine salt powder.

[0025] Ultrasonic extraction: Place the mixed medicinal powder into an ultrasonic extraction vessel, and add 10 times the volume (by weight, 630 kg) of 60% ethanol solution. Turn on stirring and ultrasound, controlling the temperature at 50±2℃ and the ultrasonic power at 400W, and extract for 45 minutes. Filter and collect the first extract. Add 8 times the volume of 60% ethanol solution to the residue again, and perform a second extraction under the same conditions for 30 minutes. Filter and combine the two extracts.

[0026] Concentration: The combined extracts were finely filtered using a plate and frame filter press (equipped with 200-mesh filter cloth). The filtrate was transferred to a double-effect concentrator and concentrated to a thick extract with a relative density of 1.15 at 60°C under vacuum conditions of -0.07 MPa and 60°C.

[0027] Mixing and Drying: The fine salt powder obtained in step 1 is thoroughly mixed with the thick extract in a mixing tank. Then, it is dried using a centrifugal spray drying tower with the inlet air temperature set at 170℃ and the outlet air temperature controlled at 85℃, yielding a light brown powder. Finally, it is passed through a 90-mesh sieve to obtain approximately 15.2 kg of the finished Tibetan medicine composition.

[0028] Example 2: Preparation of Tibetan medicine composition (adjustment of formula ratio) Formula: 15 kg of sweet osmanthus, 30 kg of raspberry, 15 kg of spruce, and 12 kg of bright salt.

[0029] Preparation process: Same as in Example 1.

[0030] Example 3: Preparation of Tibetan medicine composition (process parameter adjustment) Formula: Same as Example 1.

[0031] Adjustments to the preparation process: ethanol concentration was changed to 55%, material-to-liquid ratio was changed to 1:9 (g / mL), ultrasonic temperature was 45℃, power was 350W, extraction time was 50 minutes, and extraction was performed only once. The mixture was concentrated to a relative density of 1.18. Spray drying inlet air temperature was 165℃. The rest was the same as in Example 1.

[0032] Example 4: Preparation of sanitary napkins with added Tibetan medicine composition (core layer addition) Take 50 mg of the Tibetan medicine composition powder prepared in Example 1, and in the core layer forming section of the sanitary napkin production line, use a precision powder spreading device to evenly spread it into the absorbent core layer formed by mixing fluff pulp and superabsorbent polymer (SAP). Then, sequentially laminate the top layer (non-woven fabric) and the bottom layer (PE film), and through processes such as embossing, slicing, and packaging, produce a sanitary napkin containing Tibetan medicine ingredients.

[0033] Example 5: Preparation of sanitary napkins with added Tibetan medicine composition (topcoating) Microcapsule preparation: Take 100g of the Tibetan medicine composition powder prepared in Example 1, mix it with 200g of 10% water-based acrylic binder, add an appropriate amount of deionized water to dilute to a solid content of about 20%, and homogenize it three times under a pressure of 40 MPa using a high-pressure homogenizer to initially form an emulsion.

[0034] Coating: Use a scraper to evenly coat the above-mentioned medicated emulsion onto the back side (i.e. the side in contact with the core layer) of the non-woven fabric (PE / PP composite non-woven fabric) of the sanitary napkin surface layer, with a coating amount of 15g dry weight per square meter of non-woven fabric.

[0035] Drying and Lamination: After drying in 80℃ hot air, it is then laminated with the absorbent core and bottom layer to form a sanitary napkin. This method allows the active ingredients to be closer to the skin, resulting in faster efficacy.

[0036] Comparative Example 1 The composition was prepared using a traditional water extraction method: Following the formulation in Example 1, the mixture was decocted twice with water (10 times the volume of water, 1.5 hours each time), the decoctions were combined, concentrated, mixed with Guangming salt powder, dried, and pulverized. The resulting powder was dark in color, highly hygroscopic, and had poor flowability.

[0037] Experimental Example: In vitro antibacterial effect test 1. Experimental materials: The powder of the composition prepared in Example 1 and Comparative Example 1; Bacterial strains: Staphylococcus aureus (ATCC6538), Escherichia coli (ATCC 8739), and Candida albicans (ATCC 10231).

[0038] 2. Experimental Method: The agar diffusion method (Oxford cup method) was used. The bacterial suspension was prepared and spread onto agar plates. Sterile Oxford cups were placed on these plates, and drug-containing solutions (concentration 100 mg / mL) were added. After incubation at 37℃ for 24 hours, the diameter of the inhibition zone was measured.

[0039] The Tibetan medicine composition prepared in Example 1 of this invention has a significant inhibitory effect on three common pathogenic bacteria, and the effect is significantly better than that of samples prepared by traditional water extraction method, proving that the ultrasonic extraction process used in this invention can more effectively extract antibacterial active ingredients. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
