Comparative Assessment of Three Medicinal Plants against Diabetes and Oxidative Stress Using Experimental and Computational Approaches

Abstract

The hilly and rural areas’ people of Bangladesh have a great history of putting into use numerous traditional medicinal plants to cure diseases. Therefore, with ethanol extract of Molineria capitulata (EEMC), methanol extract of Trichosanthes tricuspidata (METT), and methanol extract of Amorphophallus campanulatus (MEAC), we mandate evaluation of in vitro α-amylase inhibition, antioxidants, and molecular docking, and ADMET/T analysis. According to iodine starch methods, α-amylase inhibition was performed, and quantitative total phenolic and flavonoid content was determined by established methods, whereas DPPH free radical scavenging and reducing power assays were performed in previously established protocols, respectively. A comparative study among three plants (EEMC, METT, and MEAC) possessed a significant ( p < 0.01 ) effect but EEMC showed the highest impact on enzyme inhibition. Plants in the measuring phenolic content METT and flavonoid measurement MEAC displayed most potent in the same way in the DPPH test was METT, and in reducing power capability MEAC has showed the highest effect between three extracts. Docking’s study also reveals the compounds of METT (Cyclotricuspidoside A and Cyclotricuspidoside C) exhibit the superior score among all the compounds. This finding indicates that EEMC, METT, and MEAC substantially impact α-amylase inhibition along with antioxidants. In silico study also reveals the potency of these plants, but further in-depth, precise molecular studies are needed.

Alternative therapeutic strategies in diabetes management

“…A different approach can arise from the use of plant extracts that are rich of polyphenols, characterized by an anti-diabetic effects. Promising in vitro results have been obtained using extracts from Coronopus didymus [ 90 ], Molineria capitulata , Trichosanthes tricuspidate , Amorphophallus campanulatus [ 91 ], Datura metel L [ 92 ]. Furthermore, in alloxan induced diabetic rats the anti-hyperglycemic and anti-oxidant roles of the 1,3,4-oxadiazole derivative[ 93 ] was found, whereas extracts of Centella asiatica leaf[ 94 ] affected weight, insulin level, and antioxidant factors compared to the control group.…”
