: Composition, Pharmacological Effects and Derived Release Systems-A Review.

is a medicinal plant rich in biologically active compounds which is used worldwide for its therapeutic effects. Chemical studies on its composition have shown that it contains mainly flavonoids, terpenoids, phenolic acids, tannins, and essential oil. The main active constituents of are volatile compounds (geranial, neral, citronellal and geraniol), triterpenes (ursolic acid and oleanolic acid), phenolic acids (rosmarinic acid, caffeic acid and chlorogenic acid), and flavonoids (quercetin, rhamnocitrin, and luteolin).

Mesoporous Silica Platforms with Potential Applications in Release and Adsorption of Active Agents.

In recent years, researchers focused their attention on mesoporous silica nanoparticles (MSNs) owing to the considerable advancements of the characterization methods, especially electron microscopy methods, which allowed for a clear visualization of the pore structure and the materials encapsulated within the pores, along with the X-ray diffraction (small angles) methods and specific surface area determination by Brunauer-Emmett-Teller (BET) technique. Mesoporous silica gained important consideration in biomedical applications thanks to its tunable pore size, high surface area, surface functionalization possibility, chemical stability, and pore nature. Specifically, the nature of the pores allows for the encapsulation and release of anti-cancer drugs into tumor tissues, which makes MSN ideal candidates as drug delivery carriers in cancer treatment.

Evaluation and Exploitation of Bioactive Compounds of Walnut, Juglans regia.

In the last few years, great importance has been given to natural materials (such as walnuts, peanuts, chestnuts) due to their medicinal and pharmaceutical uses induced by the presence of natural agents, including polyphenols. Juglans regia is a traditional plant that has been used since ancient times in traditional medicine for the treatment of various diseases like microbial infections, stomach ache, thyroid dysfunctions, cancer, heart diseases and sinusitis. Recently, scientific attention for the phytochemical profile of walnut by-products is increasing due to their valuable active constituents.
