  • Silicagel colum chromatography of the ether extract of the fruits of Angelica decursiva $F_R$. et SAV. gave four crystalline products of coumarins and one steroid. The following furocoumarins and ${\beta}-sitosterol$ were identifed by UV, IR, NMR spectra and physicochemical tests: ${\beta}-sitosterol$, iso-imperatorin, imperatorin, bergapten, umbelliferone.

  • Silica gel column chromatography of the ether extract of the root of Angelica Koreana $M_{AXIMOWICZ}$ (Umbelliferae) gave five kinds of crystalline products of coumarin. The following kinds of furocoumarins were identified by UV, IR, NMR spectra and physico-chemical tests. iso-imperatorin m.p. 108-$109^{\circ}$ $C_{16}H_{14}O_{4}$ oxypeucedanin m.p. 142-$143^{\circ}$ $C_{16}H_{14}O_{5}$ prangolarine m.p. 104-$105^{\circ}$ $C_{16}H_{14}O_{5}$ imperatorin m.p. 100-$101^{\circ}$ $C_{16}H_{14}O_{4}$ These analyses also showed that white needles m.p. 129-$130^{\circ}$ were likely to be a furocoumarin. Besides, the methanol extract of the root was found to contain sucrose.

  • Angelica flaccida Kom. is a herbal plant growing wild in the marsh of valley in Korea. It has been used for sedative and analgesic as a folk medicine, but its constituents have not been clarified yet. Five known coumarins such as isoimperatorin, decursidin, (-) anomalin, decursin, decursinol and two sterols such as ${\beta}-sitosterol$ and stigmasterol were isolated from the root of this plant, Their structures were identified by the UV, IR, NMR, mass data and the physico-chemical properties.

  • Silica gel column chromatography on the ether extract from the fruits of Angelica gigas $M_{AKAI}$ gave two kinds of crystalline constituents. The following derivatives of coumarins were identified by IR, NMR spectra, elemental analysis and physico-chemical tests: iso-imperatorin $(mp\;108{\sim}109^{\circ},\;C_{16}H_{14}O_4)$ and decursidin $(mp\;60{\sim}61^{\circ},\;C_{24}H_{26}O_7)$.
