Theacrine, a purine alkaloid obtained from Camellia assamica var. kucha, attenuates restraint stress-provoked liver damage in mice.
Li WX, Li YF, Zhai YJ, Chen WM, Kurihara H, He RR. Li WX, et al. J Agric Food Chem. 2013 Jul 3;61(26):6328-35. doi: 10.1021/jf400982c. Epub 2013 Jun 18. J Agric Food Chem. 2013. PMID: 23678853
In this study, we isolated theacrine from Camellia assamica var. kucha and investigated its protective effects on liver damage induced by restraint stress in mice. Results showed that 18 h of restraint stress could induce liver damage, with an obvious increase in le …
