Streptomycin sulfate	(++)	(++)	(+++)	(++)	(++)

Petroleum ether and acetone (4:1, V/V) were used as the solvent for TLC. The data presented in the table are the R_f values of the antibacterial activity; –, an inhibition zone was not observed; +, the inhibition zone diameter ranged from 0 to 5 mm; ++, the inhibition zone diameter ranged from 5 to 10 mm; +++, the inhibition zone diameter was greater than 10 mm; the positive control streptomycin sulfate was only sampled on the TLC plate
