The present study is to isolate and characterize betulinic acid ricinine from T. conophorum seeds. Phytochemical investigation on hexane fraction of seeds led the isolation two compounds, Betulinic (1), Ricinine (2). were screened against HepG2 cells tested in vivo CCl4-induced experimental rats model. Results this showed that compounds had hepatoprotective cytotoxic activities. It was observed inhibited cell with percentage inhibition 54% compared standard doxorubicin (64%), while inactive...
Purpose: To evaluate the effects of an okra-based diet on streptozotocin-induced diabetes mellitus in adult Wistar rats and its mechanism action.Methods: (6) were administered streptozotocin (50 mg/kg ip) after overnight fast. Upon confirmation mellitus, animals fed ad libitum for 21 days with formulated okrabased test place normal diet. The treated similarly served as diabetic control while not negative control. Thereafter, sacrificed, fasting bloodcollected analysed glucose concentration...
The present study investigated the combinatorial effect of gallic acid and catechin (GC) on some biochemical inflammatory parameters in CCl4-mediated hepatic damage to rats. Male Wistar rats were distributed equally into five groups. Group A (control) received distilled water orally olive oil intraperitoneally (ip), group B intoxicated with CCl4 {1.25 ml/kg oil, ip) only, while Groups C, D E induced CCl4, thereafter they administered 50 mg/kg body weight silymarin, combined dose (50 100 bw,...
Background:Aframomum danielli is used in ethno-medicine for the treatment of several ailments and as a traditional food spice. Methods: The hydro-distilled leaf, stem, seed, rhizome pod volatile oils A. were subjected to gas chromatography-mass spectrometry (GC-MS) analysis. Free radical scavenging capacity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) ferric reducing antioxidant power (FRAP) assays. Results: Thirty-nine (39) compounds identified danielli, accounting 85.33 96.03%...
Abstract The present study was designed to evaluate the hypolipidemic activity of Tetracarpidium conophorum oil and its mechanism(s) action. extracted using Soxhlet method subjected column chromatography/spectroscopic techniques. GC-MS analysis performed on identify 15 constituents with 9,12,15-octadecatrienoic acid (ω-3 fatty or α-linolenic acid) (68%) showing highest proportion. Isolation purification gave three compounds, namely, β-sitosterol, stigmasterol, stearic (octadecanoic acid)....
Type 1 diabetes mellitus is an autoimmune disorder characterized by the destruction of pancreatic beta cells, leading to impaired insulin production and regulation. Recent research has shown that medicinal plants with antioxidant anti-inflammatory properties hold promise as potential therapeutic agents for managing complications disease. The aim this study investigate anti-diabetic, antioxidant, effect ethyl acetate extract Annona muricata leaves in streptozotocin (STZ)-induced Wistar rats....
Purpose: To investigate the potential anti-diabetic effect of supplementing a diet with Eucalyptus camaldulensis leaves in streptozotocin (STZ) induced Wistar rats.
