Lauric acid (LA), a common constituent of coconut oil, is used as food additives and supplements in various formulations. Despite various potential pharmacological properties, no scientific evidence on its dose-related toxicity and safety is available till date.The current study was conducted to evaluate acute oral toxicity of LA on normal rats.The study was conducted in accordance with the Organization for Economic Co-operation and Development guidelines (OECD 423) with slight modifications. LA was administered orally to female Sprague Dawley (SD) rats (n = 6/group) at a single dose of 300 and 2,000 mg/kg body weight, respectively, while normal control received vehicle only. Animals from all the three groups were monitored for any behavioural and toxicological changes and mortality for two weeks. Food and fluid consumption, body weight was monitored on daily basis. At the end (on day 15th) of the experimental period, blood was collected for haematological and biochemical analysis. Further, all the animals were euthanized, and internal organs were harvested for histopathological investigation using four different stainings; haematoxylin and eosin, Masson trichrome, Periodic Acid Schiff and Picro Sirius Red for gross pathology through microscopical observation.The study results showed no LA treatment-related mortality and morbidity at two different dosages. Daily food and water consumption, body weight, relative organ weight, haematological, and biochemical analysis were observed to be normal with no severe alterations to the internal tissues.The current finding suggests that single oral administration of LA, even up to 2,000 mg/kg body weight, did not exhibit any signs of toxicity in SD rats; thus, it was safe to be used on disease models in animals.

Diabetes mellitus (DM), a prevalent metabolic condition that impairs glucose metabolism, causes morbidity and hospitalization. Thus, there is need to establish novel therapeutics against DM. The current study examined the phytochemical analysis and antidiabetic effects of Carissa grandiflora leave extracts (CGLE) on streptozotocin (STZ)-induced DM in mice. CGLE (n-hexane, chloroform, ethanol) was extracted and phytochemically examined for primary and secondary metabolites. Fourier transformed infrared spectroscopy (FTIR) detected functional groups, while 2,2-diphenyl-1-picrylhydrazyl (DPPH) test assessed antioxidant capacity. Later, antidiabetic potential of CGLE extract was investigated in vivo in STZ induced diabetic mice. Phytochemical investigation revealed sugars, ketones, alkaloids, triterpenoids, and glycosides. FTIR indicated phenol, aldehyde, ketone, alkene, alkyne, alcohol, benzene ring and amines, while DPPH assay demonstrated antioxidant potential of extract. Oral CGLE treatment significantly improved body weight (P<0.05), polyphagia and polydipsia (P<0.05) and FBG (P<0.001). Moreover, CGLE extract reversed histopathological alterations in the pancreas, liver, and kidney of diabetic mice. These outcomes highlighted that C. grandiflora extract could be effective therapeutic approach against DM.
Medicinal plants contain a wide variety of bioactive phytoconstituents which can serve as new therapeutic agents for several diseases. This study examines the antidiabetic potential of Aitchisonia rosea in alloxan-induced diabetic rats and identifies its bioactive phytoconstituents using GC-MS. In vitro, antidiabetic potential was established using the α-amylase inhibition assay. In vivo, antidiabetic potential was investigated by employing the oral glucose tolerance test (OGTT). GC-MS analysis was used to identify the bioactive phytoconstituents. The in vitro and in vivo tests showed that the aqueous extract of A. rosea possesses better antidiabetic potential. The α-amylase inhibition assay highlighted an IC
