Field screening for fungus inducing active substances from Dalbergia odorifera / 中国药学杂志

ABSTRACT

OBJECTIVE: To select the fungi which can induce Dalbergia odorifera to produce active substances. METHODS: Twenty-five fungi were inoculated in the stems of six or seven-year-old D. odorifera under natural conditions. Fungi with biological activity to induce D. odorifera producing active substances were obtained through field screening and chemical quality evaluation. The ethanol-soluble extractives and total flavonoids of D. odorifera were analyzed by spectrophotometry and hot maceration method, respectively. RESULTS: Six active fungi inducing the formation of heartwood were obtained. CONCLUSION: This study is very important for utilizing fungi in the induction of D. odorifera and sustainable utilization of this special medicinal material.
