摘要：

Root cultures of Angelica gigas Nakai were found to be sensitive to elicitation by polysaccharide elicitors, such as methyl-beta-cyclodextrin, glucan, carboxymethyl-beta-chitin, chitosan, yeast extract and pectin. For the production of decursinol angelate, carboxymethyl-beta-chitin and glucan were found to be the most efficient elicitors. The enhanced accumulation of decursinol angelate was proportional to the increase of the phenylalanine ammonia-lyase (PAL) activity after the treatment with most of the elicitors. However, carboxymethyl-beta-chitin treatment did not stimulate the PAL activity, despite the 1.6-fold increase in the decursinol angelate production.
