Technological Aptitudes and Pharmaceutical Applications of Schinus terebinthifolius Raddi Leaf and Seed Oil and Fruit Powders of Ziziphus jujuba Mill

This study is aimed at describing, controlling, and improving the technological aptitude and the traditional pharmacopeia of Schinus terebinthifolius Raddi conventionally used by the local population of Tizi-Ouzou (northern Algeria) and justifying the possible industrial applications of the plant. The study involved the drying of Schinus terebinthifolius Raddi leaves using two types of drying process (hot air drying and open air drying). In addition, the evaluation of certain properties (physical and chemical, rheological and biological) of the obtained powders was carried out. Various gels were prepared using the powders of air-dried Schinus terebinthifolius Raddi leaves, DIC (instant controlled pressure-drop) swell-dried Ziziphus jujuba Mill fruits, and seed oil of the same fruit. These plants have been used traditionally for treating gastric disorders, wounds, and rheumatic pains. Schinus terebinthifolius Raddi is also used as an antiseptic and antihelmintic agent. The results of the analysis of Schinus terebinthifolius Raddi powders have shown important chemical constituents (Na, Mg, Fe, and K), bioactive substances (polyphenols, tannins, and fatty acids), and very interesting biological activities. The obtained gels confer better physical and chemical (slightly acidic gels) properties, a higher availability of phenolic compounds, and better rheological (viscous gel) and organoleptic properties than their chemical counterparts.
