Abstract

From the roots and rhizomes of Sinodielsia yunnanensis, three new sesquiterpenes were isolated and their structures were established as 5α,6β-H-1(10),3,7(11)-guaiatrien-12,6α-olide (1), 5α,6β,7β-H-1(10),3-guaiadien-12,6α-olide (2) and 5β-hydroxy-10α-O-angeloyl-3-oxodauc-8-ene (3) by means of spectroscopic analyses and single-crystal X-ray experiment (for compound 1).
