The invention discloses a preparation process of a lavender residue antioxidant active substance, and belongs to the technical field of plant activity extraction. Residue obtained after essential oil is extracted from lavandula angustifolia through a steam distillation method is used as a raw material, an extraction process is optimized through a response surface method, and an extract rich in antioxidant active substances is obtained after AB-8 macroporous resin purification. The extract can effectively inhibit tyrosinase activity and melanogenesis of B16F10 cells induced by alpha-melanotropin hormone (alpha-MSH), can reduce the content of malondialdehyde (MDA) in HepG2 cells damaged by oxidative stress and improve the activity of superoxide dismutase (SOD), has an adjusting effect on inflammation-related factors generated in RAW264.7 cells, can inhibit release of proinflammatory factors, and can be used for preparing an anti-inflammatory drug. The melanin content and tyrosinase activity in the zebrafish body can be reduced. The invention provides an efficient and low-cost solution for application of lavender residues in the field of whitening and skin care.

The invention discloses a preparation method of natural plant essential oil modified antibacterial nanocellulose, and relates to the technical field of material science, fresh lavandula angustifolia is used as a raw material, after cleaning and crushing, supercritical CO2 extraction is adopted to refine essential oil, and bamboo pulp cellulose is subjected to TEMPO oxidation and high pressure homogenization to prepare nanocellulose. The preparation method has the advantages that the lavender essential oil is extracted by adopting a supercritical CO2 extraction technology, so that the damage of a traditional organic solvent to active ingredients of the essential oil is avoided, and the integrity and the high activity of natural antibacterial ingredients are ensured; the problems that an existing material is single in antibacterial function and short in time efficiency and cannot meet the requirements of high-end medical scenes are solved, then the layered double hydroxide nanosheet load slow release technology is combined, the antibacterial time efficiency is remarkably prolonged, the limitation of the existing material is broken through, and a more reliable and more effective antibacterial solution is provided for high-end medical treatment.

The invention relates to an anti-aging composition for repairing staying up late injury and regulating pressure, a skin care product and a preparation method of the anti-aging composition and the skin care product. The anti-aging composition and the skin care product are prepared from lavandula officinalis extract, silybum marianum extract and rice fermentation liquor according to the mass ratio of (0.1-5): (0.01-2.75): (0.1-18). Compared with the prior art, through the synergistic effect of the lavandula angustifolia extract, the silybum marianum extract and the rice fermentation liquor, cell metabolism is accelerated by regulating pressure, and endogenous aging is retarded; by preventing light aging caused by ultraviolet rays and slowing down exogenous aging caused by environmental factors, endogenous aging and exogenous aging are slowed down at the same time through the synergistic effect of the three components.
