J. Planar Chromatogr. 36, 237-249 (2023). HPTLC of the leaves of Ficus benghalensis on silica gel with toluene - ethyl acetate 93:7. Detection under UV light at 254 and 366 nm. Bioautography by pouring Bacillus subtilis culture over the plate, followed by incubation at 37 °C for 24 h. After incubation, 1 mL of 0.2 mg/mL p-iodonitrotetrazolium chloride was added to the bioautography plates and monitored at room temperature until a pink color developed. Zones of inhibition were selected and further analyzed by high-resolution liquid chromatography (HR-LC) and mass spectrometry (MS).
