The methanolic extract from the roots of Angelica furcijuga KITAGAWA was found to exhibit protective effects on liver injury induced by D-galactosamine (D-GalN) and lipopolysaccharide (LPS). From the methanolic extract, seventeen coumarins, two phenylpropanoids, and two polyacetylenes were isolated
From the methanolic extract with vasorelaxant activity obtained from Angelica furcijuga Kitagawa, four new khellactone-type coumarins, hyuganins A, B, C, and D, were isolated together with twelve known coumarins, two known acetylenic compounds, and a known lignan. The structures of hyuganins A, B,
The methanolic extract (200 mg/kg, p.o. and i.p.), principal coumarin constituents (isoepoxypteryxin, anomalin, and praeroside IV), and a polyacetylene constituent (falcarindiol) (25 mg/kg, i.p.) from the roots of Angelica furcijuga protected the liver injury induced by D-galactosamine
OBJECTIVE
To investigate the chemical constituents from Angelica keiskei.
METHODS
The constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography, and preparative TLC. Their structures were identified on the basis of spectral data and physiochemical
The aerial parts of several Angelica species of the Apiaceae as natural medicine, are rich sources of various coumarins with biological, to a lesser extent, toxicological activities. From the chloroform extract of the aerial parts of Angelica urumiensis MOZAFF. two new coumarins (1, 2), together
