Identification of a New Antibacterial Sulfur Compound from Raphanus sativus Seeds

Table 1

Antibacterial activity of radish seed ethanol extract tested against pathogenic bacteria, using the agar well diffusion method. Each value is the mean ± standard deviation of three replicates.

Pathogenic bacteria	Inhibition zone (mm)
	Extract	Chloramphenicol (10 mg/mL)
S. pyogenes	20 ± 2	30 ± 2
S. aureus	11 ± 2	15 ± 1
E. coli	19 ± 0	27 ± 2
K. pneumoniae	9 ± 2	16 ± 3
S. typhimurium	16 ± 3	29 ± 2

Inhibitory zones in mm, including diameter of the well (6.0 mm); mean ± standard deviation of three replicates.
The concentration of the extract was 130–200 mg/mL; 70–80 μL was added to each well.
15 L was added to each well.
