We studied a substance that inhibits the growth of lactic acid bacteria in samac (Machranga grandifolia) bark added to basi (Philippine sugarcane wine).1. The aqueous extract of samac bark was divided into six fractions by ultrafiltrations.The fraction of molecular weight above 2×10^5 contained 52.8% of the polyphenol component in the aqueous extract of samac bark, and greatly inhibited the growth of lactic acid bacteria, so the polyphenol component was found to be the main inhibitory substance for the growth of lactic acid bacteria in samac bark.2. The polyphenol component or molecular weight above 2×10^5 was fractionated by ion-exclusion chromatograph on CM-Sephatrose CL-6B. A polyphenol component of a polymer that greatly inhibited the growth of lactic acid bacteria was isolated.3. We presumed that the polyphenol component of the polymer that greatly inhibits the growth of lactic acid bacteria is a condensed tannin of catechin and leucoanthocyanin, since the polypoenol component of the polymer released catechin, anthocyanidins, and sugars upon hydrolysis with hydrochloric acid.
