Chemical investigation of the aerial parts of Aster subspicatus afforded a new sesquiterpene lactone, 8α-acetoxy-1α-hydroxy-3α4α-epoxy-5α, 7αH-9,11(13)-guaiadien-12,6α-olide (1), in addition to the known compounds arteglasin-B (2), diversoside (3), and 2-phenylethyl β-D-glucopyranoside. Re-investigation of Aster ageratoides afforded the known compounds crotocorylifuran, and oplopanone. The structure of the new compound was determined by spectroscopic methods particularly high resolution 1H, 13CNMR, DEPT, 2D 1H-1H and 1H-13C COSY NMR and HMBC analysis.
