Thin-layer chromatography (TLC) of extracts from endophytic fungi strains, SMB-18, SMB-20, SMB-22, and SMB-28 that were shown in the TLC plate as 18, 20, 22, and 28, respectively. Compounds with chromophores or high unsaturation observed under visible light (A). The presence of conjugated double bonds observed under UV light at 254 nm (B). The presence of flavonoids stained with aluminum chloride and illuminated under UV light at 365 nm (C). Compounds stained with p-anisaldehyde, indicating the presence of terpenes (purple spots) and flavonoids (red spots) (D). Phenolic compounds stained with ferric chloride (E).
