various biological activities, such as antitumor, antimalarial, antifeedant, insecticidal, antiinflammatory, amoebicidal, and herbicidal effects. We are interested in such biologically active compounds and have isolated many quassinoids from plants, such as Brucea antidysenterica, Picrasma ailanthoides, and Brucea javanica. As part of these studies, we investigated the isolation of quassinoids ...

About 130 species of genus Anthemis occur throughout the world. Thirty-nine of them could be found in flora of Iran. According to literature, this species was not the subject of research up to now and therefore its chemical composition is not well known. However, flavonoids, polyphenolic acids, terpene and sesquiterpene compounds were reported to be the major constituents of some other species ...

Two new triterpenoid saponins (1, 2) were isolated from the roots of Gypsophila altissima L. (Caryophyllaceae), together with a known compound (3). The structures of new saponins were established as quillaic acid 3-O-beta-D-xylopyranosyl-(1-->3)-beta-D-glucuronopyranoside (1), and 3-O-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-beta-D-glucuronopyranosyl quillaic acid 28-O-(6-...

In this study, the antimicrobial and antioxidant activities of Vicia villosa, Trifolium ochroleucum and Onobrychis altissima samples were investigated. For this purpose, plant extracts were tested against 3 fungus, 4 Gr(-) and 3 Gr(+) bacteria; additionally the glutathione (GSH) level and total phenolic content were measered spectrophtometrically and total antioxidant capacity (TAC) was done by...
