This spray is light green and has an aromatic scent.

[0039] In this embodiment, the extraction conditions are mild, and the selection of ethanol concentration and temperature ensures effective dissolution of the active ingredients.

[0040] The dual extraction design fully utilizes plant-based raw materials, and the concentration and settling steps enhance the purity of the extract. Moderate stirring is employed during formulation to ensure uniform dispersion of components, resulting in a stable spray product.

[0041] Example 2

[0043] As a preferred embodiment, it comprises the following components in weight percentage: 35% pine needle extract, 10% Albizia bark extract, 10% Polygala tenuifolia extract, 1.5% cedarwood essential oil, 1.5% lavender oil, 15% ethanol, and 27% purified water.

[0044] The preparation method includes the following steps:

[0045] First, the pine needle extract was prepared.

[0046] Take 1400g of fresh pine needles, add 47.5% ethanol (ethanol to pine needles volume ratio of 6:1), heat to 87.5℃ for the first extraction, and continue for 1.5 hours. During this period, control the temperature fluctuation to not exceed 2℃ to optimize the dissolution efficiency. After extraction, filter with medium-speed filter paper and collect the filtrate.

[0047] The second extraction was performed by heating to 87.5°C for 1 hour, followed by filtration and collection of the filtrate. The filtrates were combined and concentrated to a concentration of 12.5% ​​in a vacuum concentrator at a pressure of 0.08 MPa and a temperature of 55°C.

The temperature was controlled at 25℃, and the mixture was stirred at 400rpm for 45 minutes until it was evenly mixed and the solution was clear and free of visible impurities, thus obtaining 1000g of the plant compound spray.

[0053] In this preferred embodiment, the ethanol concentration and extraction temperature are optimized to balance extraction efficiency and component stability, the standing time is extended to ensure better clarification, and the stirring conditions enhance the uniformity of the material, making it suitable for large-scale preparation.

[0054] Example 3

[0055] This embodiment provides a plant compound spray with calming and sleep-aiding effects and its preparation method.

[0056] As a further embodiment, it is composed of the following components in weight percentage: 45% pine needle extract, 15% Albizia bark extract, 15% Polygala tenuifolia extract, 2.5% cedarwood essential oil, 2.5% lavender oil, and 20% ethanol.

[0057] The preparation method includes the following steps:

[0058] First, prepare the pine needle extract by taking 1800g of fresh pine needles and adding 55% ethanol. The volume-to-mass ratio of ethanol to pine needles is 7:1. Heat to 95℃ for the first extraction, which lasts for 1.5 hours. During the extraction, stir at a speed not exceeding 200rpm to promote the dissolution of substances but avoid foaming. After extraction, filter with a vacuum filter and collect the filtrate.

[0059] For the second extraction, heat to 95°C for 1 hour, then filter and collect the filtrate. Combine the filtrates and concentrate to a concentration of 15% using a rotary evaporator at 50°C. After concentration, let stand for 24 hours, and collect the supernatant as the pine needle extract, yielding approximately 450g.

[0060] Next, the preparation of Albizia bark extract was carried out. 600g of Albizia bark was taken and 55% ethanol was added. The volume-to-mass ratio of ethanol to Albizia bark was 7:1. The mixture was heated to 95℃ for the first extraction, which lasted for 1.5 hours. The filtrate was then collected by filtration.

[0061] For the second extraction, heat to 95°C for 1 hour, then filter and collect the filtrate. Combine the filtrates, concentrate to a concentration of 15%, let stand for 24 hours, and take the supernatant as the Albizia bark extract, yielding approximately 150g.

[0062] Further, the preparation of the Polygala tenuifolia extract was carried out. 600g of Polygala tenuifolia was added to 55% ethanol (ethanol to Polygala tenuifolia volume ratio 7:1), and the mixture was heated to 95℃ for the first extraction, which lasted for 1.5 hours. The filtrate was collected after filtration. A second extraction was performed at 95℃ for 1 hour, and the filtrate was collected after filtration. The filtrates were combined and concentrated to a concentration of 15%, allowed to stand for 24 hours, and the supernatant was taken as the Polygala tenuifolia extract, yielding approximately 150g.

[0063] Finally, the formulation is prepared. Take 450g of pine needle extract, 150g of Albizia bark extract, 150g of Polygala tenuifolia extract, 25g of cedarwood essential oil, 25g of lavender oil, and 200g of ethanol, add them to a sealed mixing container, and stir at 500rpm for 60 minutes until well mixed and free of bubbles or separation, to obtain 1000g of plant compound spray.

[0064] In this embodiment, high concentration of ethanol and temperature improve extraction efficiency, extended standing time ensures extract purity, and closed stirring enhances product stability, making it suitable for specific high-concentration requirements.

[0065] In summary, a synergistic plant-based compound spray is formed by combining pine needle extract, albizia bark extract, and polygala extract with cedarwood essential oil and lavender oil.

[0066] Furthermore, pine needle extract contains volatile components, such as terpinene compounds, which provide a basic calming effect for the spray; Albizia bark extract and Polygala tenuifolia extract are rich in saponins, traditionally used to relieve emotional tension and enhance the calming effect; cedarwood oil and lavender oil act on the olfactory system through volatile aromatic components, further promoting relaxation; ethanol acts as a solvent and stabilizer to assist in the dissolution and dispersion of active ingredients, and purified water adjusts the overall concentration to ensure that the spray form is suitable for application.

[0067] Meanwhile, the extraction process employs a two-stage heating extraction, based on the principle of gradual release of components with different solubility: the first extraction targets easily soluble substances, while the second extraction replenishes the remaining active ingredients, thereby improving the utilization rate of raw materials.

[0068] The selection of ethanol concentration range (40-55%) and heating temperature (80-95℃) balances the requirements of extraction efficiency and component stability, and avoids high temperature damage to heat-sensitive substances.

[0069] The filtration step removes solid residues, the concentration process reduces the amount of solvent by depressurization or rotary evaporation, and the static separation utilizes the principle of gravity precipitation to further purify the extract.

[0070] The spray works through both environmental evaporation and skin absorption. Volatile components, such as essential oils, affect the olfactory nerve, indirectly regulating mood; the active substances in the extract are absorbed in trace amounts through the skin, supplementing the overall effect. The simplicity of the manufacturing process and the selection of natural ingredients reduce potential risks and meet the needs of green health care.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
