Abstract

------15/11/2019------(OCR) Page 1 of 1 Abstract of Invention This invention aims to prepare lipid nanoparticle components for encapsulating extracts from the herb *Arundo donax* and the methods for preparing such particles. These particles can be prepared from two formulations: one containing only solid lipid compounds and another containing both solid and liquid lipid compounds working together to optimize application. Both formulations can enhance the efficiency of the extract, reduce the amount of substance used, and improve cell entry efficiency for the application of the nanoparticles, particularly in pharmaceuticals. One formulation of the invention, the composition for preparing lipid nanoparticles for encapsulating active ingredients, includes *Arundo donax* extract, solid lipid compounds, solvent, surfactant, and intermediate. Another formulation, also consisting of *Arundo donax* extract, solid lipid compounds, liquid lipid compounds, solvent, surfactant, and intermediate, is presented. ------------ Page 1 of 1 Abstract of Invention This invention aims to prepare lipid nanoparticle components for encapsulating extracts from *Arundo donax* and the methods for preparing such particles. These particles can enhance the efficiency of extracts, reduce the amount of active ingredient used, and improve cell entry efficiency. This facilitates the application of nanoparticles, particularly in pharmaceuticals. One form of invention for preparing lipid nanoparticles to encapsulate active ingredients consists of: A. Active ingredient (0.1-5% by weight of total components), B. Solid lipid compounds (0.1-2.5% by weight of total components), C. Solvent (0.5-60% by weight of total components), D. Surfactant (2-20% by weight of total components), and E. Medium (total volume 100% by weight of total components). A unique characteristic is that the active ingredient is an extract from *Amaranthus emblica*. Another form of invention for preparing lipid nanoparticles to encapsulate active ingredients is also presented. It consists of: A. Active ingredient, 0.1-5% by weight of total components; B. Solid fat compounds, 0.1-2.5% by weight of total components; C. Liquid fat compounds, 0.1-2.5% by weight of total components; D. Solvent, 0.5-60% by weight of total components; E. Surfactant, 2-20% by weight of total components; F. Medium, adjusted to a volume of 100% by weight of total components. Its specific characteristic is that the active ingredient mentioned above includes an extract from the ringworm plant.
