The medicinal constituents contained in Korean and Chinese Angelicae dahuricae Radix were compared by confirming their qualities. From the extracts of Angelicae dahuricae Radix, oxypeucedanin, imperatorin, and alloisoimperatorin etc. furanocoumarin derivatives were identified by GC/MS analysis. Through GC/FID analysis, the furanocoumarin derivatives content of Baizi cultivated in Korea was more than that cultivated in China, except for one cultivated at Ankuk province, and so confirmed to possess, on the whole, good quality medicinal constituents by content, as compared with the ones cultivated in China.

In our efforts to discover novel phytoestrogens to treat menopausal symptoms, eleven furanocoumarins were isolated from Angelica dahurica and tested for their estrogenic activity on the Ishikawa cell line. Among the compounds tested, 9-hydroxy-4-methoxypsoralen and alloisoimperatorin showed strong abilities to induce alkaline phosphatase (AP) with $EC_{50}$ values of 1.1 and $0.8\;{\mu}g/mL$, respectively, whereas the other nine furanocoumarins were weakly or only slightly active.
