| Study Title | Untargeted metabolomics analysis of three tea cultivars. |
| Study Type | leaf tissue |
| Study Summary | To compare flavonoid metabolism in three tea cultivars, namely Camellia sinensis cv. "Jinfenghuang" (JFH), "Fuyun 6" (FY6) and "Bantianyao" (BTY), fresh tea leaves were plucked, rapidly ground to fine powders in liquid nitrogen and subjected to extraction by 70% methanol. The extracts were analyzed by UPLC-Quadrupole Time-of-Flight Mass Spectrometry (UPLC-QTOFMS) using an ACQUITY UPLC system in tandem to a SYNAPT G2-Si QTOF mass spectrometer (Waters, Milford, MA, USA), following the previously described method. Raw data were processed in Progenesis QI (v2.4, Nonlinear Dynamics) with default settings for peak picking and alignment. Metabolites were annotated by searching against our in-house MS/MS spectral library and public databases. |

Sample Preparation:
| Sampleprep ID: | SP003182 |
| Sampleprep Summary: | Leaves were ground into a fine powder using a pre-cooled mortar and pestle. Tea leaf powder (30 mg) was extracted with 1.0 mL of 70% methanol using ultrasonication for 20 min. After centrifugation, the supernatant was filtered through a PVDF filter (0.22 µm, Millipore). |
