Analysis of metabolome content in leaves, bracts and lupulin glands of hop.
| α Acids | β Acids | Cohumulone | Colupulone | XN | DMX | Total Oils | |
|---|---|---|---|---|---|---|---|
| hop sample | % w/w | % w/w | % rel | % rel | % w/w | % w/w | % w/w |
| lupulin glands | 26.06 ± 14.0 | 17.44 ± 7.8 | 26.1 ± 4.63 | 51.4 ± 7.29 | 1.63 ± 0.78 | 0.76 ± 0.06 | 3.24 ± 8.3 |
| bracts/bracteoles * | 5.39 ± 0.85 | 3.44 ± 0.26 | 23.2 ± 3.87 | 42.9 ± 5.18 | 0.39 ± 0.08 | 0.11 ± 0.03 | 1.24 ± 0.41 |
| leaves | 0.22 ± 0.08 | 0.16 ± 0.07 | ND | ND | 0.01 ± 0.00 | ND | 0.14 ± 0.03 |
* for this analysis lupulin-enriched part of the bracts was not excised from the sample. The values represent the mean ± standard errors of four different samples (n = 4). The samples were taken from three wild-type hop plants (cv. Osvald 72) grown in the field condition in 2017. ND: not detected.
