Alkaloid | Lot 1 | Lot 2 | Lot 3 | Average (RSD; n = 3 lots) |
---|---|---|---|---|
Vicine | 282 | 316 | 319 | 306 ± 21 (6.7%) |
Convicine∗ | 66 | 91 | 86 | 81 ± 13 (16%) |
Divicine∗ | 4 | 4 | 4 | 4 ± 0 (0%) |
Isouramil∗ | 5 | 10 | 10 | 8 ± 3 (40%) |
Sum | 357 | 421 | 419 | 399 ± 36 (9.0%) |
∗The concentrations of convicine, divicine, and isouramil were estimated using the vicine standard curve (with adjustment for MW differences).
