Abstract

The plant has been utilized in folk medicine. Analyzing phytochemical composition of dichloromethane/methanol (1 : 1) root part of gave oleic acid (), caffeic acid-2-hydroxynonylester (), catechin (), and a pregnane derivative (). NMR spectroscopy was used to characterize compounds , while compound was identified through GC-MS analysis and literature comparison. The cytotoxicity of extracts from roots of was conducted against MCF-7 cell lines (human breast cancer) by MTT assay. According to the cytotoxicity study, -hexane extract exhibited a high level of toxicity with 28.9 ± 5.6% cell viability. Antibacterial activity was tested against , , , and The highest bacterial growth mean inhibition zone was measured for catechin (3) (13.72 ± 0.05 mm)) against at 0.25 mg/mL and acceptable related to standard. Antioxidant activity was studied by the DPPH assay. Based on the data from the antioxidant study, DCM/MeOH extract (70.32%) and catechin () showed good antioxidant activity (65.61%) (IC 0.25 g/mL) relative to that of the positive control (78.21%, IC 0.014 g/mL) at 12.5 g/mL. In each docking pose, catechin () scored higher binding affinity of -7.9, -7.2, and -6.4 kcal/mol towards PqsA, DNA gyraseB, and PK, respectively, compared to amoxicillin (-8.1, -6.1, and -6.4 kcal/mol). All five Lipinski rules were obeyed by compounds , which showed an acceptable drug resemblance. The lipophilicity was computed as less than five (1.47-4.01) indicating a lipophilic property. Catechin () obeys Veber's rule implying its good oral bioavailability. Binding affinity scores of catechin ()-protein interactions are in line with those from tests, indicating its potential antibacterial effect. The obtained cytotoxicity and antibacterial activity results support the utilization of in folk medicine.
