From the roots of Angelica sachokiana (Karjag.) M.Pimen. et V.Tikhomirov (Apiaceae Lindl.), collected in the phase of fruiting isolated four substances: C12H8O4, m.p.188–191 °C (I, IR: 1732, 1621, 1583 cm-1; 1H NMR: 6,30, d., J=9,65 Hz, H-4; 8,20, d., J=9,65 Hz, H-3, 7,30, s., H-8; 7,40 d., J=2,00 Hz, H-3'; 8,00, d., J=2,00 Hz, H-2'); C12H8O4, m.p. 145–146 °C (II, IR: 1730, 1630, 1600, 1560 cm-1; 1H NMR: 6,32, d., J=9,65 Hz, H-4; 7,73, d., J=9,65 Hz, H-3; 7,32, s., H-5, 6,80, d., J=2,00 Hz, H-3'; 7,60, d., J=2,00 Hz, H-2'); C13H10O5, m.p. 117–119 °C (III, IR: 1740, 1628, 1580, 1545 cm-1; 1H NMR: 3,95, c., CH3O–; 4,10, c., CH3–O–; 6,45, d., J=11,00 Hz, H-4; 8,15, d., J=11,00 Hz, H-3; 7,25, d., J=2,30 Hz, H-3'; 8,15 ppm, d., J=2,30 Hz, H-2') and C21H22O7, m.p. 136–137 °C (IV, IR: 3487, 1716, 1646, 1625, 1605, 1580, 1546 cm-1). Saponification with an alkali substance IV formed angelic acid oxypeucedanine hydrate that are identified on the basis of IR, 1H, 13C, 13C Dept 135 NMR spectra. On the basis of chemical and spectral data the substance I, II, III and IV identified as bergaptene, xanthotoxin, pimpinellin and ostruthol, respectively.
