Investigation of Lactone Chiral Enantiomers and Their Contribution to the Aroma of Longjing Tea by Odor Activity Value and S-Curve.
Zhu J, Cao X, Niu Y, Xiao Z. Zhu J, et al. J Agric Food Chem. 2023 May 3;71(17):6691-6698. doi: 10.1021/acs.jafc.3c00860. Epub 2023 Apr 21. J Agric Food Chem. 2023. PMID: 37083459
Odor activity value (OAV) and S-curve were used to study the content, proportion, and contribution of lactone chiral enantiomers in Longjing tea. A total of 10 enantiomers were identified in this study, among which (S)-(-)-delta-decalactone (45.4-84.4 mug/L), (S)-(-)-gamma …

Biochemical and transcriptome analyses of a novel chlorophyll-deficient chlorina tea plant cultivar.
Wang L, Yue C, Cao H, Zhou Y, Zeng J, Yang Y, Wang X. Wang L, et al. BMC Plant Biol. 2014 Dec 10;14:352. doi: 10.1186/s12870-014-0352-x. BMC Plant Biol. 2014. PMID: 25491435 Free PMC article.
RESULTS: The yellow-leaf tea cultivar Zhonghuang 2 (ZH2) was selected during tea plant breeding. In comparison with Longjing 43 (LJ43), a widely planted green tea cultivar, ZH2 exhibited the chlorina phenotype and displayed significantly decreased chlorophyll contents. ...
