Ethnopharmacological Relevance:
Asphodelus microcarpus is an important medicinal plant belonging to family Liliaceae. This plant is used in traditional medicine to treat abscesses by local application of the powder; the roots are used against white spots, and specifically used for ear pain.
Aim Of The Study:
The aim of the present study was to assess the in vitro antioxidant effects and the in vivo anti-inflammatory activity of the different parts methanolic extracts of the Asphodelus microcarpus: aerial part (APME), leaf (LME), stem flowers (SFME) and root (RME).
Material And Methods:
The antioxidant potency of extracts was evaluated by DPPH (2, 2-diphenyl-l-picrylhydrazyl), ABTS, β-carotene bleaching assays, iron chelating, free hydroxyl radicals (HO•) assays, and reducing power. The anti-inflammatory effect of the extracts was evaluated using the carrageenan induced rat paw edema and xylene-induced ear edema in mice.
Results:
The estimation of polyphenols and flavonoids showed that the leave methanolic extract contains a high amount of polyphenols and flavonoids: 755.3 ± 0.036 mg Gallic acid equivalent and 42.2 ± 0.043 mg Rutin equivalent/g of dried material, respectively. Oral administration of the APME and RME extract produced significant (p < 0.05) anti-edematogenic effect with a dose of 500 mg/kg in the carrageenan induced paw edema after 6 h (58.04%, 58.75%, respectively). APME, LME; SFME and RME extracts at 100, 300 and 500 mg/kg, exhibited significant (p < 0.05) inhibition of xylene induced ear edema.
Conclusion:
the present study confirms the use of A. microcarpus in traditional medicine as anti-inflammatory agent.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
