Abstract

Tanaman ranti hitam (Solanum blumei Nees ex Blumei), famili Solanaceae, ditemukan di daerah Dairi dan Karo, secara tradisional digunakan sebagai tanaman obat. Pengujian aktivitas antikanker dari ekstrak etanol buah ranti hitam terhadap sel leukemia L1210 telah dilakukan dengan metode hemositometri setelah diinkubasi 48 jam pada suhu 37°C di dalam inkubator 5% CO2. Hasil penelitian menunjukkan ekstrak etanol buah ranti hitam berpotensi sebagai antikanker terhadap sel leukemia L1210 dengan nilai IC50 sebesar 14,88 µg/mL (aktif).

Abstract

Durian leaves (Duiro zibethinus Linn.) are one of the plants whose leaves are used as a fever reducer (antipyretic). The aim of this research is to isolate natural ingredients using natural ingredient extraction techniques by maceration and identify steroid compounds from durian leaves that have anti-diabetic potential. Isolation was carried out through several stages, namely maceration, fractionation, subfractionation using column chromatography, purification using preparative TLC, and testing the purity of the isolate using TLC and determining the melting point of the isolate. The antidiabetic potential of the isolation was carried out using the α-glucosidase enzyme inhibition method. The chemical structure of the isolate was characterized using IR and UV-Vis spectroscopy. Based on IR spectroscopy analysis, the isolation has C=C, OH, O-C functional groups, C-H aromatic functional groups. UV-Vis spectroscopy data shows that there are maximum peaks at 207 nm and 247 nm, meaning that the isolated steroid compound has unconjugated double bonds. Based on spectroscopic data and comparison with reference compounds, it could be identified that the isolate obtained was β-sitosterol.
