Deodorizing, antimicrobial and glucosyltransferase inhibitory activities of polyphenolics from biosource

We evaluated the deodorizing activities of polyphenolics against methyl mercaptan and their inhibitory activity on Streptococcus mutans , Candida albicans , and glucosyltransferase responsible for oral health. Polyphenolics including eckol, dieckol, catechol, catechin, phloroglucinol, chlorogenic acid, epigallocatechin gallate (EGCG), epicatechin gallate (ECG), epigallocatechin (EGC), caffeic acid, and tannic acid were used to investigate their deodorizing, antimicrobial and enzyme activity. Among the polyphenolics, dieckol, eckol, and catechol showed higher deodorizing activity against methyl mercaptan than sodium copper chlorophyllin known as a commercial deodorant. Catechol, dieckol, and eckol exhibited a strong antimicrobial activity on S. mutans , while cinnamic acid, caffeic acid, and catechol showed a strong antifungal activity on C. albicans compared to other polyphenolics. Tannic acid, ECG, and dieckol strongly inhibited the activity of the glucosyltransferase produced by Streptococcus mutans .
