Quantification of major glucosinolates in leaves and desulfo-glucosinolates in larval feces
| Plant source | GS (common name) | GS (scientific name) | n | Leaves, μmol⋅g−1 dry weight | Feces, μmol⋅g−1 dry weight | Ratio, % |
|---|---|---|---|---|---|---|
| A. thaliana (Cvi-0) | Sinigrin | 2-Propenyl GS | 8 | 26.6 ± 2.3 | 19.0 ± 1.4 | 72 ± 4.2 |
| A. thaliana (Cvi-0) | Gluconapin | 3-Butenyl GS | 8 | 35.6 ± 3.0 | 26.7 ± 2.3 | 76 ± 4.5 |
| A. thaliana (Col-0) | Glucoraphanin | 4-Methylsulfinylbutyl GS | 10 | 11.4 ± 1.1 | 7.7 ± 0.7 | 68 ± 3.2 |
| A. thaliana (Col-0) | Glucobrassicin | 3-Indolylmethyl GS | 7 | 4.8 ± 0.2 | 2.8 ± 0.2 | 59 ± 2.8 |
| N. officinale | Gluconasturtiin | 2-Phenylethyl GS | 15 | 64.8 ± 2.7 | 41.1 ± 2.5 | 63 ± 2.2 |
Listed are plant sources and predominant glucosinolates (GS), number of experimental replicates (n), glucosinolate content in leaf halves, and desulfo-glucosinolate content in feces from fourth-instar larvae fed on corresponding leaf halves, and recovery ratios in feces vs. leaves. Given are mean values ± SE.
