ABSTRACT
A new benzofuran-type neolignan (1), two new phenylpropanoids (2 - 3), and one new C21 steroid (4) were isolated from the ethyl acetate extract of the roots of Dolomiaea souliei by chromatographic methods, including silica gel, ODS column chromatography, MPLC, and semi-preparative HPLC. Their structures were identified as dolosougenin A (1), (S)-3-isopropylpentyl (E)-3-(4-hydroxy-3-methoxyphenyl) acrylate (2), (S)-3-isopropylpentyl (Z)-3-(4-hydroxy-3-methoxyphenyl) acrylate (3) and dolosoucin A (4) through various spectroscopic techniques including 1D NMR, 2D NMR, IR, UV, HR ESI MS, ORD, and computational ORD methods.
