In-vitro and in-vivo antidiabetic activity of aerial parts of Aitchisonia rosea supported by phytochemical and GC-MS analysis.

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 IC50 value of 134.87µg/ml. In an oral glucose tolerance test, rats given an aqueous A. rosea extract significantly lowered their blood sugar levels significant reduction in the blood glucose concentration was observed in the oral glucose tolerance test in rats treated with the aqueous A. rosea extract. GC-MS investigation revealed many phytoconstituents, with serverogenin acetate and cycloheptasiloxane tetradecamethyl being important antidiabetic agents. This study found anti-diabetic properties in A. rosea extract. The phytochemical and GC-MS investigation also found serverogenin acetate and cycloheptasiloxane tetradecamethyl, which could be used to develop new antidiabetic drugs.

Phytochemical analysis and antihyperglycemic activity of Carissa grandiflora leaves extract on streptozotocin-induced diabetic mice.

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.
