In the present study, two new compounds, together with six known compounds, were isolated from rhizome of Atractylodes macrocephala Koidz by a series of silica gel, ODS column chromatography, and preparative HPLC. Their structures were characterized as atractylenolide II (1), atractylenolide I (2), biepiasterolid (3), isoatractylenolide I (4), atractylenolide III (5), 3-acetoxyl atractylenolide I (6), (4E,6E,12E)-tetradeca-4,6,12-triene-8,10-diyne-13,14-triol (7), (3S,4E,6E,12E)-1-acetoxy-tetradeca-4,6,12-triene-8,10-diyne-3,14-diol (8) on the basis of 1D, 2D NMR, and circular dichroism analyses. Among them, compounds 6 and 8 were novel compounds. In addition, their neuroprotective activity against MPP+-induced SH-SY5Y cells was evaluated by MTT colorimetry. The results showed that all these compounds have definite protective effect on MPP+-induced SH-SY5Y cells.
