Abstract Background DNA in a human cell is subjected to constant assault from both environmental factors and normal metabolic processes. Accumulation of DNA damage drives the progression of many health disorders like aging, cancer, diabetes, and neurodegenerative disorders. Results The present study focuses on the isolation of phenolic compound from the fruit of Terminalia chebula and its protective role on induced DNA damage. Diethyl ether and ethyl acetate extract of Terminalia chebula fruit were subjected to column chromatographic purification, and the fractions obtained were tested for the presence of phenolics. Fraction-12 isolated from diethyl ether extract was identified as gallic acid, which is used for cytotoxic and DNA damage protection activity assays. To select a non-toxic concentration of isolated compound, cytotoxicity was assessed by MTT assay. Gallic acid showed moderate toxicity at the highest concentration tested (i.e., percentage cell viability at 100 μg/ml is 40.51 ± 1.31). Antigenotoxic effect of gallic acid on HeLa cells was carried by alkaline comet assay. The compound showed significant protective abilities against hydrogen peroxide-induced DNA damage in HeLa cells. Conclusion These results show the importance of gallic acid isolated from Terminalia chebula fruit, as protector of oxidative stress-induced DNA damage.

AbstractThis study aimed to comprehensively analyze primary and secondary metabolites of three different-colored (white, pale green, and green) pak choi cultivars (Brassica rapa subsp. chinensis) using gas chromatography attached with time-of-flight mass spectrometry (GC-TOFMS) and high-performance liquid chromatography (HPLC). In total, 53 primary metabolites were identified and subjected to partial least-squares discriminant analysis. The result revealed a significant difference in the primary and secondary metabolites between the three pak choi cultivars. In addition, 49 hydrophilic metabolites were detected in different cultivars. Total phenolic and glucosinolate contents were highest in the pale green and green cultivars, respectively, whereas total carotenoid and chlorophyll contents were highest in the white cultivar. Superoxide dismutase activity, 2,2-diphenyl-1-picrylhydraz scavenging, and reducing power were slightly increased in the white, pale green, and green cultivars, respectively. In addition, a negative correlation between pigments and phenylpropanoids was discovered by metabolite correlation analysis. This approach will provide useful information for the development of strategies to enhance the biosynthesis of phenolics, glucosinolates, carotenoids, and chlorophyll, and to improve antioxidant activity in pak choi cultivars. In addition, this study supports the use of HPLC and GC-TOFMS-based metabolite profiling to explore differences in pak choi cultivars.
