In order to fully understand the present invention, the preferred embodiments will be described in detail below with reference to the accompanying drawings, which are not intended to limit the present invention.

The orchid leaf extract of the preferred embodiments of the present invention, the added product and the extraction method thereof are applicable to various orchids [for example: Phalaenopsis, Venus or other orchids] and their leaves [leaf or leaf] extracts , Its added products and its extraction method, but it is not intended to limit the scope of the invention. In addition, the orchid leaf extract of the preferred embodiment of the present invention is added to various processed products, such as medical products, medicines, skin care products or beauty care products, but it is not intended to limit the scope of the present invention.

Generally speaking, orchid leaves usually have multiple anti-oxidant active ingredients [such as: inhibiting hydroperoxide] and various nutritional ingredients [such as hypolipidemic components], so its extracts have high potential economic value. For example, each Phalaenopsis plant grows several thick, broad-leaved leaves, and it forms an overlapping stack on the base. Therefore, its thick, broad-leaved leaves are suitable for extraction to obtain Phalaenopsis extracts.

In addition, the orchid leaf extract has no special odor and does not affect the disadvantages of food appearance (such as food color), so it is particularly suitable for adding to various beverages (such as various tea drinks or various flower teas), alcoholic beverages [For example: orchid wine], food [for example: various pasta or various cakes], desserts, sauces, seasoning powders, health foods or health products.

For example, the orchid leaf extract is selectively added to an emulsion, a gel, an ointment, a cream, a mask, a patch, a pack, an applicator, a powder, An aerosol, a spray, an emulsion, a slurry, a paste, a foam, a dispersion, a drop, a mousse, a sun block, a suntan lotion , A tonic water, a foundation, an eye shadow, a makeup remover product, a facial soap, a soap, or various body cleansing products.

FIG. 1 illustrates a schematic flowchart of an orchid leaf extraction method according to a preferred embodiment of the present invention. Referring to FIG. 1, a method for extracting orchid leaves according to a preferred embodiment of the present invention includes step S1. First, provide a predetermined amount of orchid leaves (eg, Venus leaves), and place the orchid leaves at a predetermined temperature. [For example: -80 ° C or other suitable low temperature processing temperature] Wash and freeze to obtain a frozen orchid leaf.

Please refer to FIG. 1 again, the method for extracting orchid leaves according to the preferred embodiment of the present invention includes step S2: then, freeze-drying the frozen orchid leaves for a predetermined time (eg, 48 hours or other suitable processing time), In order to retain the tissue activity of the orchid leaves, a lyophilized orchid leaf powder is obtained.

Please refer to FIG. 1 again. The orchid leaf extraction method according to the preferred embodiment of the present invention includes step S3. Next, the lyophilized orchid leaf powder is immersed in a solution or a solvent (eg, ethanol) to form An orchid leaf extract solution.

Please refer to FIG. 1 again. The method for extracting orchid leaves according to the preferred embodiment of the present invention includes step S4. Next, the orchid leaf preliminary extraction solution is subjected to reflux reflux (reflux) extraction, and a first solvent and a The second solvent [such as ethyl acetate and hexane] is subjected to partition extraction to obtain at least one medium polarity extract and at least one low polarity extract.

In conclusion, the low-polar or medium-polar extracts of the orchid leaves can be used for physiological activities such as antioxidant [DPPH free radical scavenging, hydroxyl scavenging, and inhibition of lipid oxidation], whitening, spot removal, and prevention of melanin precipitation.

Please refer to FIG. 1 again. The method for extracting orchid leaves according to the preferred embodiment of the present invention includes step S5. Next, the low-polar extract is concentrated under reduced pressure or using a device to remove the solvent, and a third solvent is added. For example: ethyl acetate] and a solution [for example: water] for partition extraction to obtain an aqueous solution of orchid leaf extract.

FIG. 2 is a schematic diagram showing a measurement result of a radical scavenging ability of an orchid leaf extract according to a preferred embodiment of the present invention. Please refer to FIG. 2, the orchid leaf extract (for example: Venus Phalaenopsis leaf part) of the preferred embodiment of the present invention has a free radical scavenging capacity test at a concentration of 1 mg / mL [1%] with 100 The DPPH free radical scavenging effect means that it has the ability to scavenge oxidation and free radicals, so it can prevent environmental damage and combat oxidative stress.

In fact, DPPH (1,1-diphenyl-2-picryhydrozyl, C ₁₈ H ₁₂ N ₅ O ₆ ) is a stable free radical with the highest absorption peak [λ max] at a wavelength of 517 nm. When the antioxidant provides hydrogen Atoms give DPPH, and their absorption at 517 nm will also decrease. Therefore, if the absorption value of the orchid leaf extract in the preferred embodiment of the present invention decreases, it means that the higher the antioxidant clearance and the stronger the hydrogen supply capacity.

Please refer to FIG. 3, the orchid leaf extract of the preferred embodiment of the present invention (for example: water-soluble extract of Venus Phalaenopsis leaves, concentration 10%) is tested on the activity of inhibiting tyrosinase by kogic Acid as a control group, it can effectively achieve whitening, spot removal, prevention of melanin precipitation and other effects.

In general, the main source of skin melanin formation is tyrosine. In melanocytes, tyrosinase is catalyzed to convert tyrosine to dopaquinone and form melanin by oxidation. The absorption value of dopaquinone at a wavelength of 475 nm was used to determine whether the orchid leaf extract sample of the present invention has the ability to inhibit tyrosinase.

FIG. 4 is a schematic diagram showing the measurement results of the hydroxyl radical scavenging ability of an orchid leaf extract according to a preferred embodiment of the present invention. Please refer to FIG. 4. In the test of the ability to scavenge hydrogen and oxygen radicals of the orchid leaf extract of the preferred embodiment of the present invention, the low-polarity extract of the orchid leaf (eg, Venus Phalaenopsis leaf part) has Ability to remove hydrogen peroxide [H ₂ O ₂ ].

In general, the hydrogen peroxide activity is determined as the maximum absorbance of hydrogen peroxide at a wavelength of 230 nm. If hydrogen peroxide reacts with antioxidant vitamin C, its light absorption value will decrease. The lower the light absorption value, the stronger the antioxidant's ability to capture hydrogen peroxide. On the contrary, the higher the light absorption value, the more inhibited the hydrogen peroxide production ability. it is good.

FIG. 5 is a schematic diagram showing the measurement results of the lipid oxidation inhibitory ability of the orchid leaf extract of the preferred embodiment of the present invention. Please refer to FIG. 5, the orchid leaf extract of the preferred embodiment of the present invention is tested for the ability to scavenge hydrogen and oxygen radicals. The low-polar extract of the orchid leaf (eg, Venus Phalaenopsis leaf part) has lipids. Oxidation inhibiting ability, so it has protective effects such as anti-oxidation or prevention of aging, prevention of environmental damage, and oxidative stress.

In general, lipid peroxidation is determined by adding vitamin C to test samples at different concentrations, and adding vitamin C to the control group, and measuring the change in the absorption of light at 532 nm with a UV / visible spectrometer. Inhibition rate of lipid peroxidation.
