The term “officinal” derives from the Latin and includes all medicinal, aromatic and perfume plant species, which have long been a subject of interest for multiple purposes: health, food, pharmacological, cosmetic and so on. In this work, a study on six different species of medicinal plants, particularly characterized by digestive, choleretic and diuretic properties, was carried out: rosemary (Rosmarinus officinalis), sage (Salvia officinalis), laurel (Laurus nobilis), gentian (Gentiana lutea), dandelion (Taraxacum officinale) and rhubarb (Rheum palmatum). The roots and aerial parts of plants were separately extracted with two different techniques—maceration and rapid solid–liquid dynamic extraction (RSLDE)—and the quali/quantitative analysis of active ingredients have been determined by applying dry residue, Folin–Ciocalteu and DPPH assays. Data obtained have provided useful answers regarding the efficiency of the extraction carried out on a mixture or on single plants, allowing us to evaluate the best choice according to the cases and the final uses.
