“…In Europe, Asia and North America, various Verbascum species are used to for antiseptic, antimalarial, astringent, demulcent, emollient, sedative, narcotic effects and also, they are used for the treatment of tumors, inflammations, migraine, asthma and spasmodic coughs. The species are recorded to treat haemorrhoids, rheumatic pain, superficial fungal infections, wounds and diarrhoea, and have inhibitory activities against some influenza viruses [2][3][4][5].…”

In this present study, the aerial parts of Verbascum eskisehirensis were dried in the shade and air-flowed area. The dried samples were macerated with 70% methanol in water for 24 h by three times. The biological activities of the extract was determined by in vitro methods. The antioxidant activity was evaluated in 2,2'-diphenyl-1picrylhydrazyl (DPPH˙) radical scavenging assay and the trolox equivalent antioxidant capacity (TEAC) was measured the ability of the extract to scavenge the stable radical cation ABTS + (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)). The antibacterial effects against some clinical pathogens were tested by broth microdilution assay. The in vitro antiinflammatory activity was also examined by 5-Lipoxygenase (5-LOX) enzyme inhibitory test. In the same time, the phenolic composition of the extract was determined by LC-ESI-MS/MS system. According to results, the extract was found rich-in luteolin derivatives. The major compound was identified as luteolin-pentosyl-hexoside. The antioxidant activities of the extract were moderate. The extract showed weak antibacterial activity against tested bacteria strains. Salmonella typhimurium ATCC 13311 was more sensitive to the extract than the others. The extract showed weak antiinflammatory activity.

Assessing the effects of Guiera senegalensis, Pluchea odorata, and Piliostigma reticulatum leaf powder supplementation on growth, immune response, digestive histology, and survival of Nile tilapia (Oreochromis niloticus Linnaeus, 1758) juveniles before and after Aeromonas hydrophila infection

This study investigated the effects of including leaf powder from three medicinal plants collected in Senegal in the feeds of juvenile Nile tilapia (Oreochromis niloticus) on growth, survival, immunity, and digestive histology. Four experiments were conducted in triplicate, testing each plant alone or in combination at different inclusion levels: A) Guiera senegalensis at 0, 1, 2, 4 and 8%; B) Pluchea odorata at 0, 0.5, 1, 2 and 4%; C) Piliostigma reticulatum at 0, 1 and 2%; and D) a mixture of the three plants at 0, 1 and 2% per plant. After 28 days of feeding, fish underwent an experimental infection with Aeromonas hydrophila for 12 days. Immunological (bactericidal, lysozyme, and respiratory burst activities) and digestive histology analyses were performed following both feeding and infection trials. Except for G. senegalensis, the inclusion of medicinal plants, either alone or in combination, positively influenced the immune response at all inclusion levels. The diet containing 4% P. odorata increased plasma lysozyme and bactericidal activities without compromising feed conversion efficiency or growth. Despite the observed improvements in immunity, none of the dietary treatments enhanced survival following the infection. However, fish fed the 1% mixture diet exhibited healthier livers and intestines, characterized by reduced cell swelling and normal lipid deposits appearance, followed by the 2% mixture and the control groups. These results highlight the potential benefits of incorporating P. odorata and the plant mixture in the diets of Nile tilapia juveniles for enhancing their immune response and defense against A. hydrophila infections.

The effects of three medicinal plants in the feeds of juvenile Nile tilapia (Oreochromis niloticus) were investigated on growth, survival, immunity, and digestive histology at various inclusion levels: (A) Guiera senegalensis at 0, 1, 2, 4, and 8%; (B) Pluchea odorata at 0, 0.5, 1, 2, and 4%; (C) Piliostigma reticulatum at 0, 1, and 2%; and (D) a mixture of the three at 0, 1, and 2%. After 28 days of feeding, fish were infected with Aeromonas hydrophila for 12 days. The results showed that, except for G. senegalensis, the inclusion of the medicinal plants, alone or combined, enhanced the immune response. The diet with 4% P. odorata significantly increased plasma lysozyme and bactericidal activities without affecting feed conversion efficiency or growth. Despite improved immunity, none of the treatments enhanced post-infection survival rates. However, fish fed the 1% mixture showed healthier livers and intestines, with reduced cell swelling and normal lipid deposits, followed by the 2% mixture and the control. These results highlight the potential benefits of incorporating P. odorata and the plant mixture into the diets of Nile tilapia juveniles for enhancing their immune response against A. hydrophila.
