2. The process of preparing plant extracts with fresh plant biomass and cosmetics of these parts. The process includes grinding and pressing fresh plant biomass to obtain part of plant cell juice containing membrane separation. This part of the cell juice is treated with an effective frequency and separated to obtain part of the cytochrome / cytochromee of membrane fractions. The aforementioned treatment is advantageously carried out so that the temperature of said cell juice during said treatment does not exceed 40 ° C. Claim 6: The method according to claim 3It is characterized by electromagnetic fields ranging in frequency from 2.5 GHz to about 7.0 GHz. 13. Claim 13: the method in accordance with claim 1, which is characterized in that the biomass of the fresh plant comes from the selected plant families of laminaracae, cladophoracae, fabeaceae, teacae, aceseraae, lamiaae, Liliaceae, poacae and Moraceae. Claim 14: the method of claim 1, which is characterized by selecting the biomass of this fresh plant from a group consisting of macrocytis por biosphere, Chaetomorpha, mediago sativa, Trifolium pratense, Glycine max, Camellia sinensis, Calendula officinalis and Tanacetum Parthenium,Chamomilla restita, angutfolia, Salvia officinalis, Nelumbo Nuck biosphere, Lilium bulbferum, Avena sativa and Hordeum vulgareProceso para la preparación de fracciones botánicas a partir de biomasa vegetal fresca y a composiciones cosméticas hechas de dichas fracciones. El proceso comprende moler y prensar biomasa vegetal fresca con el objeto de obtener una fracción de jugo celular vegetal que contiene fracciones membranarias, y tratar dicha fracción de jugo celular con un campo electromagnético con una frecuencia efectiva para separar dicha fracción membranaria de dicha fracción de jugo celular con el objeto de obtener una fracción de citoplasma/citosol celular sustancialmente libre de fracciones membranarias. El tratamiento anteriormente mencionado se lleva a cabo de forma ventajosa
