Differences in the components of the crude drug Saposhnikoviae radix, both wild and cultivated, and the cultivation duration were examined by UHPLC/MS. As a result, there was no significant difference in composition depending on the region in China where the drug was produced. The most abundant components in all samples were prim-O-glucosylcimifugin, 4'-O-glucosyl-5-O-methylvisamminol, 3'-O-acetylhamaudol and cimifugin. The 1 year-old Saposhnikoviae radix cultivated in Japan had a low component content overall. A comparison of components according to root thickness revealed that glycosides, such as prim-O-glucosylcimifugin and 4'-O-glucosyl-5-O-methylvisamminol, were accumulated in thin roots. In a comparison of the components according to the drying temperature, a large difference was observed in the content of glycosides, and a difference was observed depending on the sugar-binding position. According to a metabolome analysis in domestic commercial products by LC/MS, a characteristic component in the cultivated product was found and its content was low in the 1 year-old sample and high in the 2 year-old sample. If the cultivation duration is prolonged up to about 6 years, the contents of the ingredients are close to those of wild products.
