The invention provides a hedera helix extract as well as an extraction method and application thereof, and belongs to the technical field of medicinal plant extraction. According to the method, natural eutectic solvents are screened, and the interaction of the solvents is determined by adopting an infrared spectrum; on the basis of single factor investigation, a response surface method is used for modeling and optimizing an extraction process of eight active components in the hedera helix so as to improve the extraction rate, and a scanning electron microscope is used for exploring the permeation effect of a natural eutectic solvent combined with an ultrasonic-assisted extraction method on plant cells from a microscopic perspective; finally, determining that the natural eutecticevaporate solvent is combined with an ultrasonic-assisted extraction method through a cell counting kit-8 method and an active oxygen detection method to obtain the hedera helix extract which has a stronger inhibition effect on HT-29 colon cancer cells.

The invention provides an oil control composition containing N-acetylneuraminic acid and application of the oil control composition in cosmetics, and belongs to the technical field of cosmetics. The oil control composition is prepared from the following components in parts by weight: 0.1 to 2 parts of N-acetylneuraminic acid, 0.06 to 2 parts of wheat germ extract, 0.001 to 0.2 part of ribonucleic acid and 0.001 to 5 parts of hedera helix extract. The four compositions in the oil control composition provided by the invention synergistically and efficiently control oil through different paths, the oil outlet state of the skin can be improved after long-term use, the essence obtained by mixing the four compositions with other auxiliary materials can maintain the siRNA biological activity, can avoid the viscosity reduction effect of N-acetylneuraminic acid on a common refreshing thickener, can regulate the oil secretion of the skin, and has the effects of whitening and whitening the skin. The composition can maintain the dynamic balance of skin surface flora, improve skin hair follicle keratinization, relieve inflammatory response, repair damaged skin and recover the natural and healthy state of the skin.

Provided are a Hedera helix extract, a preparation method therefor, and use thereof. The preparation method comprises extracting Hedera helix leaves with 75%-85% ethanol, concentrating, adjusting the pH value to 9.5-11, standing, filtering to obtain a crude extract, passing the crude extract through a chromatographic column, and eluting with 60%-80% ethanol to prepare the Hedera helix extract. The chromatographic column is an HPD100 macroporous resin column, a polyamide column or a C18 column. The Hedera helix extract can be used for preparing drugs with anti-inflammatory, expectorant, and antitussive effects, as well as for treating acute bronchitis.

The present application relates to the field of hair care products, and discloses a preparation method of a scalp barrier repair hair product based on peony flower water composition, comprising the following steps: S1: selecting fresh, non-molded, and non-diseased peony petals, removing impurities, and then washing with deionized water, draining the surface moisture, mixing the peony petals with deionized water, placing them in a distillation kettle for low-temperature distillation under reduced pressure, collecting the distillation condensate, filtering through a microporous filter membrane, obtaining refined peony flower water, and reserving it for use. The present application has the following advantages and effects: the peony phenol and polyphenol components in the peony flower water achieve strong anti-inflammatory and antioxidant effects, the combination of the spilanthes extract and the dipotassium glycyrrhizinate enhances the soothing and anti-inflammatory effects, the ceramide NP and the sodium hyaluronate supplement the scalp cuticle lipids and achieve multi-level moisturizing, and the plant extracts such as Hedera helix further improve the antioxidant and scalp nourishing effects.
