Megjegyzések:	The aim of this study was to evaluate the phytochemical profile and antioxidant properties of the extracts from three Rosa species (R. canina, R. damascena, R. cairo), to develop and investigate topical formulations with lyophilized forms of extracts for the treatment of psoriasis. Phytochemical screening and in vitro total antioxidant capacity (DPPH, FRAP, CUPRAC, SOD) of studied samples were examined and compared. Lyophilized extracts of roses were dissolved in Transcutol HP and different formulations of creams were prepared. Franz diffusion method was used to evaluate the drug release and biocompatibility was tested on HaCaT cells. Rosa damascene had the best results regarding all the analyses that were conducted. After the evaluation of topical products, the formulation with Rosa damascena extract in a self-emulsifying drug delivery system was tested on a human clinical study that involved 20 patients. At the end of the clinical study an improvement in the quality of life of the patients was observed and erythema, induration and scaling were reduced. The present study indicates that our examined extracts exhibited great phenolic content, antioxidant capacity and safety profile of topical formulation and therefore can be used as a reliable source of natural antioxidants and may be used as a complementary treatment to improve the quality life of patients with psoriasis or may be tested on another diseases.

Megjegyzések:	Background: Centaurium erythraea Rafn. (C. erythraea) is a medicinal plant traditionally used in European folk medicine for the treatment of wounds, skin inflammations, and other dermatological conditions, in addition to its well-documented systemic antioxidant and anti-inflammatory effects. However, its topical applications remain insufficiently investigated, particularly using plant material collected from Romania. The purpose of this study was to prepare different ointment formulations containing C. erythraea Rafn. extract obtained from the aerial parts of the plant, using various excipients, and to evaluate their in vitro and in vivo efficacy. Methods: The phytochemical profile of C. erythraea extract was characterized using liquid chromatography?tandem mass spectrometry (LC?MS/MS). The lyophilized extract was pre-dissolved in different solubilizing agents?Transcutol? P (diethylene glycol monoethyl ether), Capryol? 90 (propylene glycol monocaprylate), or a combination of both?and then incorporated into five ointment formulations. Texture analysis and an in vitro membrane diffusion study were performed. The antioxidant capacity of the formulations was assessed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power (FRAP), and total phenolic content (TPC) assays. Anti-inflammatory activity was evaluated in vitro using tumor necrosis factor-alpha (TNF-?)-induced interleukin-1 beta (IL-1?) production in human keratinocyte (HaCaT) cells, and in vivo using a carrageenan-induced rat paw edema model. Results: LC?MS/MS identified 18 polyphenolic compounds, with hyperoside (3.78 ? 0.05 ?g/mL), protocatechuic acid (1.13 ? 0.06 ?g/mL), chlorogenic acid (1.07 ? 0.06 ?g/mL), and quercetin (0.53 ? 0.03 ?g/mL) as the principal constituents. The formulation containing both Transcutol? P and Capryol? 90 exhibited the most pronounced antioxidant activity (65% DPPH inhibition; 69.71 ? 0.83 mg gallic acid equivalent/mL) and significantly reduced IL-1? levels by 45.7% compared to the inflamed control. In vivo, this formulation showed comparable anti-edematous effects to a methylprednisolone ointment. Furthermore, it demonstrated the highest skin permeation efficiency, with a quercetin diffusion coefficient of 35.12 ? 10?5 cm2/min. Conclusions: These findings highlight the therapeutic potential of C. erythraea extract from aerial parts in topical formulations and underscore the enhancing role of Transcutol? P and Capryol? 90 in improving both the pharmacodynamic and pharmacokinetic properties of bioactive compounds.

Leaf and Flower : antimicrobial, Antioxidant and Anti-Inflammatory Assessment of the Plant / Ágota Pető, Dóra Kósa, Ádám Haimhoffer, Dániel Nemes, Pálma Fehér, Zoltán Ujhelyi, Miklós Vecsernyés, Judit Váradi, Ferenc Fenyvesi, Adina Frum, Felicia Gabriela Gligor, Laura Grațiela Vicaș, Eleonora Marian, Tünde Jurca, Annamária Pallag, Mariana Eugenia Muresan, Zoltán Tóth, Ildikó Bácskay

Megjegyzések:	Philadelphus coronarius is a versatile plant and its use in folk medicine has a long tradition; however, scientifically, the medical utilization of the herb is a less explored research field. The aim of our study was to identify and determine the quantity of the bioactive compounds of both the leaf and the flower and prepare a lyophilized product of them, from which medical ointments were formulated, since the topical application of P. coronarius has also not been studied. In vitro drug release, texture analysis and biocompatibility experiments were carried out, as well as the investigation of microbiological, antioxidant and anti-inflammatory properties. According to our results the composition and the selected excipients of the ointments have a great impact on the drug release, texture and bioavailability of the preparation. During the microbiological testing, the P. coronarius leaf was effective against Escherichia coli and Staphylococcus aureus, but it did not significantly decrease IL-4 production when it was tested on HaCaT cells. P. coronarius is a promising herb, and its topical application in antimicrobial therapy can be a useful addition to modern medical therapy.
