Insecticidal activity of Thymus pallescens de Noë and Cymbogon citratus essential oils against Sitophilus zeamais and Tribolium castaneum.

The thrust of the study was to determine the chemical composition of the essential oils extracted from Thymus pallescens de Noé and Cymbogon citratus Stapf. as well as to evaluate their efficacy in controlling Sitophilus zeamais Motschulsky and Tribolium castaneum (Herbst) in either single or combined populations. Carvacrol (56.

Exploring the potential of extracts for antioxidant, antiproliferative and apoptotic effects on human liver cancer cells and a molecular docking study.

In folk medicine, (Asteraceae) has been traditionally utilized for treating various ailments, including diabetes, bronchitis, diarrhea, rheumatism, and injuries. In this study, we aimed to investigate the chemical composition, antioxidant, antiproliferative, and apoptotic properties of leaf extracts. Extraction was performed using solvents of varying polarities.

phenolic extract suppresses colon cancer cell proliferation and ulcerative colitis by modulating oxidative stress biomarkers.

is a perennial herbaceous plant native to the Mediterranean Basin, which is used topically for the treatment of various diseases in folk medicine. This study aimed to evaluate the intestinal anti-inflammatory activity of the ethanolic extract of (EEIV) and to test its effect on a colorectal cancer cell line. EEIV was administered to rats orally and daily at 100 and 200 mg/kg body weight for 7 days, and then colitis was induced by intrarectal instillation of 2 ml of 4% (v/v) acetic acid (AA) solution.

Semipapposides A-M, triterpenoid bidesmosides saponins from the roots of Scabiosa semipapposa.

Phytochemical investigations of the roots of Scabiosa semipapposa Salzem ex D.C. have led to the isolation of 12 undescribed triterpenoid saponins named semipapposides A-L, one undescribed saponin semipapposide M obtained as an inseparable mixture, together with three known oleanolic acid glycosides.

Concurrent measurement of cellular turbidity and hemoglobin to evaluate the antioxidant activity of plants.

In past decades, a multitude of analytical methods for measuring antioxidant activity of plant extracts has been developed. However, when using methods to determine hemoglobin released from human erythrocytes treated with ginger extracts, we found hemoglobin concentrations were significantly higher than in untreated control samples. This suggests in the presence of antioxidants that measuring hemoglobin alone is not sufficient to determine hemolysis.

Prevalence of rotavirus (GARV) and coronavirus (BCoV) associated with neonatal diarrhea in calves in western Algeria.

Objective: To study the prevalence of bovine group A rotavirus (GARV) and bovine coronavirus (BCoV) in diarrheic feces from calves and the sensitive's parameters such as age group and sex.

Methods: Feces samples from 82 diarrheic dairy calves from farms around Tiaret (Western Algeria) were collected. These samples were tested by ELISA assay.

Molecular mechanism underlying anti-inflammatory and anti-allergic activities of phytochemicals: an update.

The resort worldwide to edible medicinal plants for medical care has increased significantly during the last few years. Currently, there is a renewed interest in the search for new phytochemicals that could be developed as useful anti-inflammatory and anti-allergic agents to reduce the risk of many diseases. The activation of nuclear transcription factor-kappa B (NF-κB) has now been linked to a variety of inflammatory diseases, while data from numerous studies underline the importance of phytochemicals in inhibiting the pathway that activates this transcription factor.

Evaluation of the antioxidant activity of three varieties of honey from different botanical and geographical origins.

It is well established that honey contains substantial antioxidant compounds that could protect cell components from the harmful action of free radicals. One can speculate that these compounds may strengthen the organism defenses and consequently prevent oxidative stress in humans. Therefore, over time, impaired cells can accumulate and lead to age-related diseases.

Antibacterial and antioxidant potency of floral honeys from different botanical and geographical origins.

In order to assess their physicochemical and antioxidant properties as well as their antimicrobial potency, four varieties of honey from different botanical and geographical origins were used. The agar incorporation method was used to determine the antimicrobial potency of honeys. The total phenol content was determined by a modified Folin-Ciocalteu method and the free radical scavenging activity by the Fe(3+)reducing power (FRAP) assay.

Phytochemicals to prevent inflammation and allergy.

Recently, much interest has been generated for a wide range of phyto-constituents with reports demonstrating their role in the modulation of inflammatory responses, including phenolics, alkaloids, and terpenoids. Natural products have long been, over the years, contributed to the development of modern therapeutic drugs. At present, steroids, antihistaminic drugs, suppressants or inhibitors of the release of mediators and the like have been used as anti-allergic agents.
