191 results about "Cyanidin" patented technology

Cyanidin is a natural organic compound. It is a particular type of anthocyanidin (glycoside version called anthocyanins). It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, cranberry, elderberry, hawthorn, loganberry, açai berry and raspberry. It can also be found in other fruits such as apples and plums, and in red cabbage and red onion. It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH < 3, violet at pH 7-8, and blue at pH > 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. In a recent study, cyanidin was found to be a potent sirtuin 6 (SIRT6) activator.

Vaccinium uliginosum cyanidin and separation and purification method thereof

The invention relates to an anthocyanidin made from Vaccinium uliginosum L. and separation and purification methods thereof, which belong to the technology field of active component extraction and purification and functional food development. The content of anthocyanidin in Vaccinium uliginosum L. is 29.8-40%, wherein the content of malvidin accounts for 4.68-5.48% of the anthocyanidin; and antioxidant activity of the anthocyanidin is as 7.8-15 times as that of Vc. The preparation method includes pre-treating raw material, cold soaking and concentrating, purifying and concentrating, and freeze dying. The ultrasonic and microwave-assisted cold soaking method is employed for separation, and an AB-8 macroporous resin static-dynamic combined absorption purification method is employed. The invention provides an environmental friendly, high-efficiency and low-cost separation and purification technology of anthocyanidin made from Vaccinium uliginosum L., which maintains product bioactivity such as antioxidant property of product and ideal separation effect, establishes the basis for wide utilization of abundant resource of Vaccinium uliginosum L. and industrialized development promotion of a series of Vaccinium uliginosum L. health food, and embodies great economic benefit and social benefit in deep processing of the Vaccinium uliginosum L.

Blueberry leaf health care beverage and preparation method thereof

The invention provides a blueberry leaf health care beverage. The beverage comprises the following materials in weight portion: 30 to 50 portions of blueberry leaf, 10 to 30 portions of blueberry fruit, 5 to 10 portions of seabuckthorn fruit, 10 to 20 portions of rose hip and 10 to 20 portions of cordyceps militaris, and active ingredients of the materials are extracted by microwave technique to prepare the beverage. In all materials, vitamin C is abundantly contained, particularly, cyanidin composition and flavonoid contained in the blueberry leaf can delay ageing, improve the immunity of human body and obviously improve eyesight of people and has a plurality of physiological activities such as blood sugar and blood fat adjustment, and the like; the cyanidin composition is a natural bacteriostat, colorants and bacteriostats are not necessary to be added, and flavoring agents such as citric acid are not necessary to be added to regulate the acidity, which is more helpful to the health of human body. By the verification of experiments and the experience of people, the health care beverage is easily absorbed by human body and taken conveniently, and can obviously improve the eyestrain of human body; moreover, the health care beverage also has the characteristics of unique formula, reasonable composition, simple process, body building-up, remarkable function and the like.

Treatment method for enhancing stability of blueberry cyanidin

The invention relates to a treatment method for enhancing stability of blueberry cyanidin. The treatment method comprises the following steps: extracting with a 0.5% trifluoroacetic acid (TFA) methanol solution, and sequentially purifying through an ion exchange resin column Amberlite XAD-7 and a Sephadex column Sephadex LH-20 to obtain a blueberry cyanidin refined substance; carrying out nutgall acylation reaction on the blueberry cyanidin refined substance and prepared triacetyl nutgall acyl chloride to introduce galloyl group with ortho-triphenolhydroxy group into the molecular structure, thereby obtaining the modified product nutgall acylated cyanidin. When high-performance liquid chromatography is used for determining the gallic acid amount generated after hydrolyzing the modified product, the nutgall acylation degree is 55-63%. The experiment proves that the stability of the modified product is obviously enhanced. The method for treating blueberry cyanidin is simple to operate, and has the advantages low cost, low pollution and high acylation degree. The molecular modification can enhance the primary characteristics of the blueberry cyanidin, so that the effects are enhanced; and multiple functional groups are introduced to endow the blueberry cyanidin with new physiological activity, thereby widening the application range.

Protection effect of cyanidin-3-glucoside for UVB (ultraviolet B)-induced HaCaT cell injury

The invention discloses a protection effect of cyanidin-3-glucoside (C3G) for UVB (ultraviolet B)-induced cell injury. The protection effect particularly includes that generation of ROS (reactive oxygen species) of HaCaT cells due to UVB can be reduced by the C3G, accordingly, antioxidant effects can be realized, DNA (deoxyribonucleic acid) can be protected against injury, the survival rate of the HaCaT cells can be increased after the UVB irradiates on the HaCaT cells, and apoptosis reducing effects and the like can be realized. The protection effect has the advantages that the oxidation injury of the selected representative HaCaT cells which are cultivated in vitro is induced by means of UVB irradiation, light injury models of epidermal cells due to ultraviolet rays are imitated, then the C3G is used as a light injury protector, effects and relevant channels of the C3G for relieving UVB injury of the HaCaT cells are evaluated, the protection effect, action mechanisms and the safety of the C3G for light injury of skins are investigated, and accordingly theoretical foundation is laid for clinically effectively preventing and treating light injury of the skins and studying ultraviolet radiation injury protection action mechanisms of natural plant antioxidants.
