A new psolaren derivate, (E)-9-(3,4-dimethylpent-2-enyloxy)-7H-furo[3,2-g]chromen-7-one, has been isolated and characterized by experimental and theoretical methodologies. The solid state molecular structure has been determined by X-ray diffraction methods. The substance crystallizes in the monoclinic P21/c space group with a=4.

- Six compounds were isolated from the aerial parts of the Argentinean plant Hymenoxys robusta, using advanced spectroscopic techniques to determine their structures.
- The isolated compounds include two inositol derivatives and four 3,4-seco-pseudoguaianolides, one of which is called vermeerin.
- Vermeerin demonstrated antimicrobial activity specifically against Staphylococcus aureus and was non-toxic to human-derived macrophages in bioactivity assays.
The flowers of Hyaloseris salicifolia afforded known ivasperin, while the leaves afforded ivasperin and 2-O-(6'-O-acetyl-beta-D-glucopyranosyl)-ivasperin, whose structure was determined by spectroscopic methods.
