Objective: To study the chemical constituents of Angelica keiskei. Method: The constituents of A. keiskei were isolated and purified by silica gel column chromatograph and Sephadex LH-20 column chromatograph. Their structures were elucidated on the basis of spectral analysis such as IR

1H-NMR

13C-NMR and MS. Result: Seven compounds were obtained by separation and purification

they were identified as 1-cerotol(1)

daucosterol(2)

stigmasterol(3)

quercetin-3-O-β-D-glucopyranside(4)

luteolin-7-rhamno-glucoside (5)

luteolin-7-O-α-D-glucpyranoside(6) and steviol-l3-O-β-glucopyranoside 19-β-glucopyranosyl ester octaacetate(7). Conclusion: The seven compounds were first isolated from A. keiskei.
