Abstract

The invention provides a preparation method of a Cistanche tubulosa extract and a skin-whitening anti-aging cosmetic. The preparation method comprises pulverizing, performing crude extraction, centrifugally collecting the obtained crude extract, standing, eluting, and drying to obtain the Cistanche tubulosa extract. The preparation method is simple, and has no pollution. The extract has the content of echinacoside not lower than 25%, the content of verbascoside not lower than 55%, and the content of total glycosides not lower than 80%. Proven by the antioxidant activity test, the Cistanche tubulosa extract has antioxidant, skin whitening and anti-aging effects. The skin-whitening anti-aging cosmetic is prepared by adding the Cistanche tubulosa extract into a cosmetic, is safe and free of stimulation proven by cytotoxicity and safety test, and also has good skin whitening effect.

Description

technical field [0001] The invention relates to a preparation method of Cistanche tubulosa extract used as a cosmetic raw material, and belongs to the technical field of deep processing of natural plants. Background technique [0002] Cistanche is a natural health product. Chinese and foreign scientists have used modern medical technology experiments to prove that: Cistanche contains phenylethanol glycosides, echinacoside, verbascoside and other life active substances; Japanese scientists discovered "life-supporting factors" from Cistanche and "Life-saving wine" was developed. The latest research results prove that Cistanche has significant curative effects such as anti-aging, preventing and treating middle-aged and elderly "dementia". [0003] For example, Chinese patent 200510126563.6 discloses that Herba Cistanche has the effect of preventing skin dullness. In recent years, due to unreasonable large-scale mining of its resources, serious damage has been caused, and the s...
