is a plant traditionally used for its anti-inflammatory, antioxidant and antispasmodic effects, as well as for additional biological activities proven in cell culture, animal studies and a small number of human clinical trials. The plant has also shown a marked improvement in blood lipid profile in some animal species. In the present preliminary study, we investigated the effect of a leaf extract on lipid and oxidative blood profile of hypercholesterolemic volunteers. Twelve adults received extract caps, containing 23% phenylpropanoids, (100 mg, once a day) for 16 weeks. Selected blood lipids and plasma oxidative markers were measured at baseline and after 4, 8 and 16 weeks of treatment. Compared with baseline, total cholesterol levels significantly decreased and high-density lipoprotein cholesterol increased, while low-density lipoprotein cholesterol and triglycerides showed only a downward trend. Oxidative status was improved due to a decrease in the concentration of total oxidant status, reactive oxygen metabolites and malondialdehyde, and a significant increase in ferric reducing ability of plasma, vitamin A and vitamin E. These preliminary results suggest that dietary supplementation with extract can improve the lipid profile, enhance blood antioxidant power, and could be a valuable natural compound for the management of human hypercholesterolemia.

The chemical constituents from the stems and leaves of Mycetia hainanensis were isolated by silica gel, ODS gel, and Sephadex LH-20 gel column chromatography and preparative HPLC. The chemical structures of all the isolated compounds were identified on the basis of their physicochemical properties, spectroscopic data, as well as the comparison of their physicochemical and spectroscopic data with the reported data in literature. Twelve compounds were isolated from the 85% ethanol extract of the stems and leaves of M.

Fire blight, caused by Erwinia amylovora, is a significant threat to fruit crops, with limited biocontrol methods. This study aimed to develop a nanosystem using mesoporous silica nanoparticles (MSNs) loaded with a phenolic plant extract (ZP) derived from Myrtus communis, Thymus vulgaris, and Curcuma longa, and coated with natural biopolymers Gum Tragacanth (GT) and sodium alginate (SA). The MSNs were synthesized and characterized by XRD, FTIR, and TEM, exhibiting a specific surface area of about 750 m/g and an average pore diameter of 5 nm.

The effect of the aqueous extract of (AAI) on gentamicin (GEN)-induced kidney injury was investigated. The study involves 20 adult male Wistar rats (housed in four separate plastic cages) such that graded dosages of AAI were administered to the experimental group for 14 days per oral (PO) before exposure to GEN toxicity (100 mg/kg) for 1 week. At the end of the study, comparisons of some markers of renal functions, antioxidant status, and inflammatory and apoptotic markers were made between the control, GEN, and AAI-pretreated groups at < .

Drought stress remains a serious concern in L. var , cultivar Satabdi (IET4786) production, particularly during the earliest growth phases, ultimately affecting yield due to the recent trend of delayed rain arrival in West Bengal, India. This study aimed to develop a cost-effective strategy to improve the drought tolerance capacity of rice seedlings by priming the seeds with flavonoid-enriched extract (FEE) of French marigold () petals to withstand the initial drought milieu.

Fine particulate matter (PM2.5) is known to exacerbate chronic respiratory disorders, primarily by inducing inflammatory responses and mucus overproduction. Perilla leaves are reported to have significant health benefits, such as antioxidant, antibacterial, and antiallergic properties, attributed to phenolic compounds that vary depending on genetic diversity.
