Synergistic Sustained Drug-Release System Based on Immobilized L. Phytoextract into Layered Double Hydroxide Covered by Biocompatible Hydrogel.

This work focuses on the synergetic effect obtained by immobilization of L. phytoextract in layered double hydroxides (LDHs) matrixes and their subsequent encapsulation into biocompatible hydrogels (HG). In this respect, the LDHs were used as hosts for the immobilization of the phytoextract by a reconstruction method, after which the LDHs were embedded into biocompatible hydrogel (HG) matrixes, based on polyethylene glycol diacrylate (PEGDA), by a radical polymerization reaction.

The Biological Effects of Novel Nutraceuticals with Curcuminoids and Other Plant-Derived Immunomodulators and Pre-Probiotics.

An effective and well-balanced immune system is pivotal for maintaining health. Diet and nutrition can affect the functioning of numerous immune parameters, with direct repercussions on homeostasis. Since our immune functions are indispensable in defending the body against pathogens and thus play a vital role in maintaining health, modulating immune response may well serve as the basis for the development of plant-based functional foods and novel nutraceuticals.

Straightforward Preparation of Naphtodianthrone-Rich Ethanolic Extracts from Wild St. John's Wort.

Separation of naphtodianthrones (NTs) from Hypericum perforatum L. (aerial part of St. John's Wort) is still topical due to some hard-to-beat medicinal attributes of these bioactive compounds.

What's in the box? Authentication of Echinacea herbal products using DNA metabarcoding and HPTLC.

Background: Differences in regulatory policies between countries as well as a lack of appropriate standardized methods for the authentication and quality control of herbal products directly impact their quality and safety. Echinacea products are among the top-selling herbal products in Europe and the United States with indications for a broad range of ailments. The increased use of Echinacea species has led to concerns about adulterated products resulting from challenges in morphology-based identification, due to overlapping morphological variation, frequent hybridization between species, and deliberate adulteration.
