The aim is to explore the phytochemical profile, antioxidant capacity, and antidiabetic effects of Garcinia lanceifolia leaf extracts.
Extracted leaves using aqueous decoction and ethanol maceration at different concentrations.
Conducted qualitative screening for phytochemicals and quantified total phenolic and flavonoid content.
Used GC-MS to identify bioactive compounds and evaluated antioxidant activity with DPPH and ABTS assays.
Performed in vitro enzyme inhibition assays for α-glucosidase and α-amylase.
Identified consistent presence of alkaloids, saponins, and terpenoids; tannins and steroids in higher ethanol extracts.
The 95% ethanol extract had the highest TPC and TFC values, indicating rich bioactive compound content.
Exhibited the strongest antioxidant activity in DPPH and ABTS assays.
Showed concentration-dependent enzyme inhibition with strong efficacy for both α-glucosidase and α-amylase.
