  • The phytochemical study of the aerial parts of Artemisia japonica ssp. littoricola (Asteraceae) led to the isolation of two acetylenic compounds, (3R)-dehydrofalcarinol (2) and (3R)-dehydrofalcarindiol (6), two sesquiterpenes, $1{\beta}$, $6{\alpha}$-dihydroxy-4(15)-eudesmene (5) and oplodiol (8), and four phenolic compounds, eugenol (1), vanillin (3), 3'-methoxy-4'- hydroxy-trrans-cinnamaldehyde (4) and p-hydroxyacetophenone (7). Their structures were determined by chemical and spectroscopic methods.

  • The flowers of Hemisteptia lyrata B. afforded two known acylglycerylgalactosides, 2',3'-di-O-(9Z,12Z,15Z-octadecatrienoyl)glyceryl ${\beta}$-D-galactopyranoside (1) and 2'-O-(9Z,12Z,15Z-octadecatrienoyl)glyceryl ${\beta}$-D-galactopyranoside (2), and a new sesquiterpene galactopyranoside, 7-eudesmene-1${\beta}$,4${\beta}$-diol-1-O-${\beta}$-D-galactopyranoside (3). This is the first time that galactopyranosides (1-3) have been isolated from the genus Hemisteptia. Their structures and stereochemistry were elucidated by 1D and 2D NMR data, including COSY, NOESY and HMBC experiments.

  • The chromatographic separation of a methylene chloride extract of Artemisia rubripes led to the isolation of a new sesquiterpene lactone (3), together with four known compounds, a coumarin (2) and three terpenes (1, 4, and 5). Their structures were characterized to be $1{\beta},6{\alpha}$- dihydroxy-4(15)-eudesmene (1), scopoletin (2), $1{\alpha},4{\beta}-dihydroxy-8{\alpha}$-acetoxy-guaia-2,10(14), 11(13)-triene-6,12-olide (3), $1{\alpha},4{\beta}$ -dihydroxy-8${\alpha}$-acetoxy-guaia-2,9,11(13)-triene-6,12-olide (4), and $\beta$ -sitosterol-3-O-${\beta}$-D-glycoside (5) by spectroscopic means.
