Two novel phenanthrofurans, shanciol G (1) and shanciol H (2), together with three known phenolic compounds were isolated from the tubers of Pleione bulbocodioides (Franch) Rolfe. Their structures were elucidated by spectroscopic methods.

Two new sucrose esters, beta-d-(1-O-acetyl-3-O-trans-feruloyl)fructofuranosyl-alpha-d-2',4',6'-O-triacetylglucopyranoside (1) and beta-d-(1-O-acetyl-3-O-trans-feruloyl)fructofuranosyl-alpha-d-2',3',6'-O-triacetylglucopyranoside (2), together with two known sucrose esters have been isolated from Sparganium stoloniferum. Their structures were elucidated by spectroscopic methods.

Two new triterpenoids, 25-anhydro-alisol F (1) and 11-anhydro-alisol F (2), were isolated from the rhizomes of Alisma orientalis. Their structures were elucidated by spectroscopic methods.

Two new compounds, alternanthin B (1) and N-trans-feruloyl-3,5-dimethoxytyramine (2), along with four known compounds (3-6) were isolated from the aerial parts of Alternanthera philoxeroides. Their structures were elucidated on the basis of spectroscopic methods. The antitumor activity of the isolated compounds was also evaluated.

The phytochemical study of the aerial parts of Laggera pterodonta afforded two new eudesmane sesquiterpenes, 3alpha,4beta,11-trihydroxyenantioeudesmane (pterodontriol E) (1) and 4beta,8beta,11-trihydroxyenantioeudesmane (pterodontriol F) (2), along with seven known compounds. Their structures were elucidated on the basis of spectroscopic data.

Two new sesquiterpene alkaloids, 1beta-hydroxy-2beta,5alpha,11-triacetoxy-7beta-nicotinoyl-8beta-benzoyl-dihydroagarofuran, and 1beta,5alpha,11-triacetoxy-7beta-nicotinoyl-8beta-benzoyl-dihydroagarofuran were isolated from the xylem of Tripterygium wilfordii, together with six known compounds. Their structures were elucidated on the basis of spectroscopic studies.
