Composition Profile
Verified · 2026-09-26- 01Long-term storage metabolome of compressed ShoumeiAcross samples from different storage years, 148 compounds were identified. Catechins, dimeric catechins, amino acids, phenolic acids and organic acids generally declined, while EPSF, alkaloids, lipids and flavonoid aglycones generally increased. Among 2020–2013 samples, EPSF showed a correlation coefficient of 0.882 with storage time.Dry-leaf sample
- 02Volatile terpene enantiomer profileR-α-ionone showed relatively high abundance in the Fuding Shoumei samples. Levels of several terpene enantiomers were associated with plucking tenderness and product style among Fuding white teas.Dry-leaf sample
- 03Total anthocyanin glycosidesGrade 1 Shoumei: 126.04±16.41 μg/g; Grade 2: 122.28±2.18 μg/g.Dry-leaf sample
In stored compressed Shoumei, catechins, dimeric catechins, amino acids, phenolic acids and organic acids generally decline with time, while EPSF, alkaloids, lipids and flavonoid aglycones generally increase. Its terpene and anthocyanin profiles also show product-style differences.
