Elucidating the anti-obesity potential of bioactive fractions of kalanchoe pinnata ( lam .) leaves extract using a combination of in vitro, in vivo and in silico methods along with characterisation of lead compounds through an HPTLC ms-MS n analytical study.

Fractions were isolated from the leaves extract of Kalanchoe pinnata and subjected to scrutiny for their prospective anti-obesity properties. An array of preliminar y phytochemical, invitro antioxidant, and enzyme inhibition assays were executed, which discerned fractions F1 and F2 as the most effective fractions. These fractions were subsequently studied through invivo experiments, affirming that F2 as the most potent fraction. Further characterisation of F2 was conducted via HPTLC-Mass spectrometry (MS-MS ⁿ ) techniques. The outcomes demonstrated that F2 produced a notable anti-obesity effect in obese mice, reducing their body weight and lipid metrics, and leading to advantageous changes in their organs. An analytical examination of F2 revealed the existence of four principal compounds, which were subsequently subjected to insilico molecular docking and dynamic analysis, confirming their aptitude for binding to selected proteins. These findings imply that the utilisation of Kalanchoe pinnata leaves could provide a promising therapeutic strategy for the treatment of obesity.
