Values represent the means of peak heights for standards measured by LC-MS/MS. T1–T5, Fractions isolated from strain KB21; T6, water control; N/A; not available. Data are means ± SE of three replicates. The values followed by different letters in a column were significantly different at p < 0.05 by Duncan’s multiple range test.
