Abstract

The invention discloses a preparation method of plant placenta extracts, wherein the placenta of the rare aquatic flower, namely, water lily is taken as a raw material. The preparation method comprises the following steps: removing impurities from the placenta of the fresh water lily, washing the impurity-removed placenta of the fresh water lily to be clean, draining the washed placenta of the fresh water lily, carrying out pulping, carrying out cell disruption by adopting ultrasonic waves, carrying out high-speed homogenizing, carrying out high-speed centrifugal separation on the homogenate, taking the supernate, carrying out decolorization on the supernate, and carrying out dialysis and nanofiltration to obtain the plant placenta extracts. With the adoption of the preparation method, a purely natural and efficient active skin-caring substance is provided for the field of cosmetics, in addition, the raw materials are easily available, so that the production cost is greatly reduced, and moreover, the preparation method is simple, is suitable for industrial production, and has a very high market promotion value.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and specifically relates to a preparation method of plant placenta. The extract has the effects of effectively stimulating cell regeneration, improving the oxygen supply of cells, increasing skin protein synthesis, keeping skin youthful and making skin radiant. Background technique [0002] In the Qin and Han Dynasties, the ancestors used water lily as a nourishing medicine, and the medicinal use of lotus has a history of more than 2,000 years in China. "Compendium of Materia Medica" records that lotus, lotus seeds, lotus pods, nelumbini, lotus nuts, lotus leaves, lotus stems, lotus joints, etc. are all medicinal. Lotus flower can promote blood circulation and stop bleeding, remove dampness and eliminate wind, clear heart and cool blood, relieve heat and detoxify. Lotus seeds can nourish the heart, nourish the kidney, invigorate the spleen and astringe the intestines. Lianxu can clear the hea...
