From the CHC15 extract of the aerial parts of Ononis natrix, a new natural product, N-arachidylanthranilic acid [1] has been isolated, in addition to the known compounds, gardenin B, xanthomicrol, hymenoxin, 8-hydroxy-6-methoxy-3-undecyl-3,4-dihydroisocoumarin, and medicarpin-fi-D-glucoside. The structure of 1 was established by spectroscopic and chemical methods.The genus Ononis belongs to the family Leguminosae (tribe Trifoleae) and comprises more than 75 annual or perennial species, indigenous to Eurasia, especially the Mediterranean region (1,2). Ononis

The structure of a new isocoumarin derivative, achlisocoumarin IV [1], isolated from the underground parts of Achlys triphylla was characterized by means of its spectroscopic properties. The chemical constituents of Ac. triphylla and Ac. triphylla subsp. japónica were compared by hplc to find their chemotaxonomic similarities and differences. Results showed a chemotaxonomically close relationship.
