Abstract
Tuocha is one of the special varieties of fermented compressed tea leaves, praised for its important health benefits, such as anti-aging, lowering cholesterol, enhancing immune function, lowering of blood pressure, reducing heart attacks etc. In the present study, we carried out fractionation and isolation of the active constituents, guided by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. In addition, antioxidative and antihepatotoxic potency on D-galactosamine (D-GalN)/tumor necrosis factor-alpha (TNF-α)-induced cell death in primary cultured mouse hepatocytes was also examined. Our study revealed that, tuocha is rich in antioxidants such as phenolics, lignans, flavanoides and flavan-3-ols, and showed a good understanding between structure and activity relationship.
