Abstract: | Root cultures ofAngelica gigas Nakai were found to be sensitive to elicitation by polysaccharide elicitors, such as methyl-β-cyclodextrin, glucan, carboxymethyl-β-chitin,
chitosan, yeast extract and pectin. For the production of decursinol angelate, carboxymethyl-β-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-β-chitin
treatment did not stimulate the PAL activity, despite the 1.6-fold increase in the decursinol angelate production. |
