| Title | LC-MS based untargeted metabolome analysis of Oryza |
| Description | Compounds in the Oryza species were analyzed using liquid chromatography-mass spectrometry (LC-MS) in a untargeted manner. The same analytical conditions are applied to all samples. Therefore, the compound peaks can be compared to each other by the mass values, the retention time of the LC, and the CID mass spectrum. |
