The dried roots of Angelica acutiloba Kitagawa var. acutiloba Kitagawa, A. acutiloba Kitagawa var. iwatensis Hikino and A. acutiloba Kitagawa var. sugiyamae Hikino have been used as the herbal medicine known in Japan as Japanese Angelica Root. The respective morphological features of, in particular, A. acutiloba var. sugiyamae and A. acutiloba var. iwatensis are similar, and they are not easy to distinguish morphologically from each other. In an attempt to find a method for discriminating among these three varieties, we compared the nucleotide sequence of the spacer region between the atpF and atpA genes among the respective plastid genomes. Comparison of these sequences allowed us to identify each of the three varieties unequivocally.
北川当归变种北川当归、北川当归变种岩手当归和北川当归变种杉山当归的干燥根在日本被用作草药，称为日本当归根。特别是，杉山当归变种和岩手当归变种各自的形态特征相似，在形态上彼此不易区分。为了找到区分这三个变种的方法，我们比较了各个质体基因组中atpF和atpA基因之间间隔区的核苷酸序列。通过比较这些序列，我们能够明确鉴定出这三个变种中的每一个。
