Description

Preparation method and application of blue butterfly extract with blue light resisting component

Technical Field

The invention relates to a preparation method and application of a blue butterfly extract with a blue light resisting component, and belongs to the technical field of daily chemical processing.

Background

Clitoria ternata L belonging to the family Leguminosae (Leguminosae) of Papilioideae (Papilioideae) of the genus Clitoria (Clitoria L), is known as Phaseolus vulgaris, Phaseolus lanuginosus, Phaseolus hybridus, Indian Nissia, and is cultivated in tropical and subtropical regions of the world. The sphenoidea flowers are rich in anthocyanins, with abundant vitamins A, C and E. In India, the Indian lygodium herb medicine (Ayurvedic medicine) has used the Indian lygodium herb for a medicine for enhancing memory, promoting intelligence, resisting stress, resisting anxiety and resisting depression, has the performances of resisting convulsion, calming and soothing the nerves, is considered as a good brain tonic, and the long-term use and scientific research of the Indian lygodium herb has confirmed the efficacy and the modern significance. The blue butterfly is rich in a wide range of secondary metabolites including 13 kinds of anthocyanins, flavonols, glycosides and other phenolic compounds. Phenolic compounds have potent antioxidant activity and are considered as the most desirable free radical pathological therapeutic drugs. The presence of the antioxidant activity of the oroxylum indicum indicates that the oroxylum indicum is likely to be an alternative source of natural antioxidants. Moreover, flavonoids, anthocyanins and other substances are reported to improve the smoking quality of cigarettes to a certain extent. Therefore, the blue butterfly has quite high economic value and research significance. However, the research on the blue butterfly is generally applied to the research on the secondary metabolite of the blue butterfly and the drug development, the application of the blue butterfly extract to cosmetics is rarely reported at home and abroad, and the application value of the blue butterfly extract in the cosmetics is hardly developed. Many plants provide opportunities for the organic combination of characteristic plants and cosmetics due to beneficial components possibly contained by the plants and special fragrance and aroma components.

Among all visible light, blue light is the shortest wavelength, the highest energy, near UVA in the ultraviolet, especially short-wavelength blue light of 400-. Blue light can penetrate through crystalline lens to damage retina, and can stimulate brain to inhibit melatonin secretion, improve adrenal cortical hormone production and affect sleep quality. In addition, blue light can penetrate the epidermis to the dermis, causing skin darkening, staining, and aging. Unlike ultraviolet light, it is found not only in sunlight, but also in a large number of computer monitors (whether LEDs or CCFLs), digital electronic product display screens, mobile phones, televisions, and even automobile lights, neon lights. Therefore, the extract of the plant of the Indian buead has good prospect in cosmetics.
