Phenolic compounds from the edible seeds extract of Chinese Mei (Prunus mume Sieb. et Zucc) and their antimicrobial activity

Antimicrobial efficacy of plant phenolic compounds against Salmonella and Escherichia Coli

“…Also, strains, culture medium and/or the methods used in the experiments could have contributed to antimicrobial resistance of E. coli against quercetin. High antimicrobial activity was observed with chlorogenic acid (MIC was o20 ppm) for all bacteria tested in accordance with the previous studies (Albayrak, Aksoy, Sagdic, & Budak 2010;Babic, Nguyenthe, Amiot, & Aubert, 1994;Xia, Wu, Shi, Yang, & Zhang, 2011); however, it was reported with a MIC of o80 (mg ml À 1 ) against Gram-negatives (Lou et al, 2011). Among the PCs tested, it exhibited the lowest MIC (o10 ppm), being consistent for all Salmonella.…”

5-O-Caffeoylquinic acid: A spectroscopic study and biological screening for antimicrobial activity

“…The antimicrobial activities of isomers decrease in order 3-CQA > 5-CQA > 4-CQA. Those results indicate that caffeoylquinic acids act in synergism (perhaps with other compounds of the extract) to exhibit strong antibacterial and antifungal activities (Xia, Wu , Shi, Yang, & Zhang, 2011). 5-CQA shows bacteriostatic activity against Streptococcus mutans (cariogenic bacteria) with MIC of 0.8 mg/mL.…”

Chemical Composition and Antioxidant Activities of Five Samples of Prunus mume Umezu from Different Factories in South and East China

“…Xia et al [23] identified three chlorogenic acid isomers, namely, 3-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, and 4-O-caffeoylquinic acid (cryptochlorogenic acid), from P. mume seeds and found 3-O-caffeoylquinic acid was of the highest level in these three isomers. In this study, we also detected the chlorogenic acid isomers in P. mume seeds but did not find them (data not shown).…”
