thegenus achillea is one of the most important medicinal plants in the asteraceae family. nineteen species of this genus have been described in the flora iranica, of which achillea aucheri boiss is an endemic species to iran. given the effect of geographic location on the quality and yield of essential oil, we performed an investigation to determine oil contents of a. aucheri growing at differe...

Background and objectives: Chromatography fingerprinting is considered as a comprehensive method for quality control, diagnosis and the nature of herbal drugs, and it is important to classify the different samples of medicinal plants and determine the chemical species present in them. Methods: In this research, a new strategy based on the combination of multiva...

Paederus fuscipes Curtis, a dermatitis linearis causing agent, has received increasing attention from the public, as it poses a serious health threat after mass dispersal into human-dominated areas. Preventive measures against this insect have so far been unsuccessful partly because of limited knowledge about its dispersal pattern. In this study, the dispersal activity of P. fuscipes was studie...

Pederine, a drug extracted from the coleopter Paederus fuscipes, inhibits the growth of in vitro cultured cell lines at concentrations of the order of 1.5 nanogram/ml. Cytological examination shows a generalized cytotoxic effect. Analysis of macromolecular syntheses by the use of radioactive precursors shows that pederine causes an almost immediate block of protein and DNA synthesis, without af...

The survival and reproduction of the beetle Paederus fuscipes Curtis on diets that differed in macronutrient composition were investigated in the laboratory. The sex organs of females fed each test diet were dissected to evaluate the ovarian development over time. Adults fed on a carbohydrate-rich diet lived longer than adults fed the other diets, but this diet provided insufficient nutrients f...

The genus Astragalus L. (Fabaceae) is reviewed from both phyloenetic and taxonomic points of view. As the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. A short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...

Study of smut fungi on Liliaceae resulted to propose a new genus and three new combinations: Vankya Ershad, type V. ornithogali (Schmidt et Kunze) Ershad, based on Uredo ornithogali Schmidt et Kunze, V. heufleri (Fuckel) Ershad, based on Ustilago heufleri Fuckel, and V. vaillantii (L.-R. et C. Tulasne) Ershad, based on Ustilago vaillantii L.-R. et C. Tulasne.

The results showed that Pileolaria terebinthi, type species of the genus Pileolaria is not a hemi–form or brachy–form rust species as mentioned among literature by several authors. Study on miscellaneous specimens collected from Iran and locus classicus of the species, France, revealed that P. terebinthi is an automacrocyclic rust and its aecial state is not uredinioi...
