The present study was to optimize the phenolic recovery from Centella asiatica by investigating the effects of ethanol concentration (0-100%, v/v), extraction time (60-300 min) and extraction temperature (2565°C) on phenolic extraction using single-factor experiments. Total phenolic content (TPC), total flavonoid content (TFC) and condensed tannin content (CTC) were used for determination of ph...

. In this paper content of phenolic compounds from black radish (Raphanus sativus L. var niger) roots of different size were examined. Black radish grown in Serbia, with the same period of development, grouped by size into three groups: (R1) with mass of 350 15 g; (R2): 100 10 g and (R3): 35 5 g, were used. Plant extracts were prepared by using 80% (v/v) ethanol and total phenolic compounds con...

This study aimed in the identification and quantification of phenolic compounds in different four varieties of rapeseeds (Brassica napus L.) using LC-MS and HPLC. LC-MS analysis guided to identify 12 phenolic compounds including sinapine, sinapine(4-O-8')guaiacyl, feruloyl choline(4-O-8') guaiacyl, kaempferol-3-O-sinapoyl-sophoroside-7-O-glucoside, kaempferol-3-O-β-sophoroside, cyclic spermidin...

We describe the first analytical method involving SPE and CZE coupled to ESI-IT MS (CZE-ESI-MS) used to identify and characterize phenolic compounds in olive oil samples. The SPE, CZE and ESI-MS parameters were optimized in order to maximize the number of phenolic compounds detected and the sensitivity of their determination. To this end we have devised a detailed method to find the best condit...

For several years, our laboratory has isolated numerous bacterial strains from soils and wastewater contaminated with toxic compounds in order to find useful bacteria that can degrade phenolic compounds such as phenol, chlorophenol, and nitrophenol. By enrichment, many phenolic compound-degrading bacteria have been isolated (Bae et al., 1996a, b; Baek et al., 2001; Yoon et al., 1999, 2000). Fur...

Chinese water chestnut (CWC) is one of the most popular foods among Asian people due to its special taste and medical function. Experiments were conducted to test the antioxidant activity and then determine the major phenolic compound components present in CWC. CWC phenolic extract strongly inhibited linoleic acid oxidation and exhibited a dose-dependent free-radical scavenging activity against...
