Over 220 crude extracts from repositories generated from plants native to Greece and Kazakhstan were evaluated for termiticidal activity against the Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae). Emerging from this screening effort were bioactive extracts from two Greek species (Echinops ritro L. and Echinops spinosissimus Turra subsp. spinosissimus) ...

A new species of eriophyoid mite, Aceria banatica n. sp. inhabiting Echinops ritro L. subsp. ruthenicus (M.Bieb.) Nyman has been described from Serbia. A comparison of characters between A. banatica n. sp. and Aceria echinopsi Boczek and Nuzzaci 1988, the only other species known from Echinops sp., is given. A supplementary description of Aceria brevicincta (Nalepa 1898) found on Jurinea mollis...

The mother tinctures of desert were screened for antibacterial activity against bacterial strains of Gram-positive and Gram-negative bacteria. Mother tinctures were prepared by maceration process and antibacterial activity of different plants was evaluated and compared by measuring their zones of inhibition. The results indicated that Boerrhavia diffusa mother tincture had excellent activity on...

The genus Echinops belonging to the Asteraceae family comprises 130 species. The dried leaves and seeds of Echinops orientalis Trauv. were extracted separately with methanol. Apigenin-7-O-(6"-trans-pcoumaroyl--D-glucopyranoside 1, and Apigenin-7-O--D glucoside 2 were isolated from leaves and 1methoxycarbonylindole 3 and beta-sitositerol 4 were isolated from seeds. The compounds were isolated ...

Echinops wakhanicus Rech.f. (Compositae: Cardueae: Echinopsinae) is described and illustrated, its taxonomic position discussed. Field observations seed collection of the species are mentioned. The genus discussed, comments made on infrageneric classification, placement E. in sect. Oligolepis. terminology used describing flowering structure discussed; term synflorescence preferred. Tribal subtr...

Echinopines A (1) and B (2), novel sesquiterpenoids with an unprecedented rearranged skeleton named echinopane, were isolated from the roots of Echinops spinosus. The structures were elucidated by extensive spectroscopic analysis. The relative configuration of 1 was assigned by a combination of NOESY correlations and a simulation analysis. A plausible biosynthetic pathway for echinopane was dis...
