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