- W3136275296 abstract "In order to clarify the contents of active principles in floral inhibition cultured Angelica gigas roots, the amounts of crude extract and the contents of decursin and decursinol angelate in the yearly roots were analyzed and compared with respect to the root age, root part and growth stage. The woody cell, weight and width of pith and cortex were also investigated at different growth stage to observe the developmental characteristics of lignification in the roots as bolting and flowering in normal cultured Angelica gigas. The amount of crude extracts did not differ with plant ages, whereas the contents of decursin and decursinol angelate were differed and the highest in 3 year old roots. The contents of decursin in 1, 2 and 3 year old roots were 3.71, 4.76 and 8.20% and those of decursinol angel ate were 2.84, 3.40 and 5.01%, respectively. The amount of crude extracts, and the contents of decursin and decursinol angelate were the highest in fine roots, followed by the lateral roots and the lowest in the primary roots. On the other hand, the amount of the constituents in the cortex were much higher than those in the pith of the root. The amounts of crude extract, and the contents of decursin and decursinol angelate showed the highest value at the vagetative stage and decreased with development to bolting and blooming stage. Woody cells were accumulated in the pith of the root as advancing growth stage, so that the weight and radius of the pith increased, whereas the relative weight and width of the cortex decreased slightly." @default.
