Antifungal and antioxidative activities of Phellodendron amurense extracts were investigated for use as a natural preservative. After separation of P. amurense into phloem, xylem, leaf and fruit each part was subjected to methanol extraction. Each MeOH extract was further fractionated with several solvents(n-hexane, methylene chloride and ethylacetate). Among the methanol extracts, extracts of phloem and leaf inhibited effectively the growth of mold fungi and rot fungi, respectively. Especially, ethylacetate fraction from phloem showed the highest growth inhibitory effects against fungi tested, such as P. citreonigrum H3, P. toxicarium H4, P. corylophilu H5, A. clavatus, P. osteatus, S. commune, and G. lucidum. The fractions of fruit, which had lower antifungal activities mostly than those of phloem, strongly inhibited rot fungi such as G. lucidum, T. versicolor, and T. palustris. Compared to ferulic acid which is well known antioxidant, ethylacetate fraction of fruit showed high antioxidative activities on concentration of 1 to 100㎍/㎖ in DPPH radical scavenging activity. As a result, antifungal and antioxidative activities of P. amurense suggest that its extract and fraction have a possibility as conservative of cultural heritage because it might get conservation effects against deteriorating microorganisms of cultural heritage.
