In this research, a single-step polymeric novel particle was synthesized from oak bark extract by nanoemulsion polymerization technique for the first time in the literature. It has been shown that the synthesized particles are achieved without losing any antioxidant and antibacterial properties of the oak bark extract. In this study, the p(OB) particles were reported for the first time and were characterized in terms of antioxidant, blood compatible, H2O2 scavenging, antibacterial, and antifungal potential to evaluate their use in biocompatible materials with drug release system potential.

Phenolic acids are one of the major fractions identified in the extract of several vegetable seed oils which present interesting antioxidant properties. A density functional theory (DFT) study on the antioxidant potential of eight phenolic acids including gallic, vanillic, isovanillic, ferulic, caffeic, β-coumaric, cinnamic, and chlorogenic acids, is presented in this paper.

In this study, we investigated the phenolic profile of L. orientalis. using HPLC, and 5 compounds from BL-1, (juglone, naringenin, rosmarinic acid, vanillic acid, echinacoside) and 4 compounds from BL-2 (juglone, apigenin-7-glucoside, naringenin, vanillic acid) were reported for the first time. A total of six new flavonoids (juglone, naringenin, rosmarinic acid, echinacoside, vanillic acid, and apigenin-7-glucoside) were identified from BL’s by HPLC analysis.

Maesa membranacea A. DC. (Myrsinaceae) has been traditionally used for the treatment of fever and hepatitis. The phytochemical investigation of Maesa membranacea stems has led to the isolation of six compounds including kaempferol (1), (-)-epicatechin (2), betulinic acid (3), p-hydroxybenzoic acid (4), vanilic acid (5), and protocatechuic acid (6). The chemical structures of these compounds have been determined by nuclear magnetic resonance (NMR), mass spectrometry (MS) data, and by comparison with previously reported works.

Ligustrazine-vanillic acid derivatives had been reported to exhibit promising neuroprotective activities. In our continuous effort to develop new ligustrazine derivatives with neuroprotective effects, we attempted the synthesis of several ligustrazine-vanillic acid amide derivatives and screened their protective effect on the injured PC12 cells damaged by CoCl2.
