Get e-Alerts Abstract Tea preparations of Ardisia compressa AC have been used in folk medicine against liver disorders. The objective of this study was to evaluate the in vitro topoisomerase I and II enzyme inhibition and the antioxidant effect of an aqueous extract from dry leaves of AC and a pure component ardisin purified from AC on benomyl Be -induced cytotoxicity in primary culture rat hepatocytes. Lipid peroxidation malondialdehyde , antioxidant enzyme activities of glutathione reductase, glutathione peroxidase, and superoxide dismutase, and glutathione levels were studied.

Get e-Alerts Abstract Aqueous extracts of the leaves of Ardisia compressa AC have been used in folk medicine to treat various liver disorders including liver cancer. The objective of this study was to partially characterize and determine the total polyphenol content, antioxidant capacity, and quinone reductase activity of A. Total polyphenol content, antioxidant capacity, and phase II enzyme induction capacity were measured by the modified Folin-Ciocalteu, ORAC, and quinone reductase QR assays, respectively.
The major polyphenols in AC were not catechins. HPLC retention times and standard spikes of AC indicated the presence of gallic acid, epicatechin gallate, ardisin and kaempferol. Using catechin as standard, the total polyphenol value of AC MT and GT showed no induction at the concentrations tested 0. These results suggest that AC has a different mechanism of protection against cytotoxicity that is not related to its antioxidant capacity.
Further studies are needed to determine such mechanisms and to explore its potential as a chemopreventive or therapeutic agent.

Abstract Chagalapoli fruit Ardisia compressa is similar to Vaccinium myrtillus berries with high-polyphenol content. The objective of this study was to evaluate the physicochemical properties of Chagalapoli fruit and to determine the conditions for the preparation of a fermented beverage using Saccharomyces cerevisiae yeast, evaluating the impact on sensory properties.
