The effects of some pretreatments including blue-green and green algae and minerals on the induction of me-tabolic and biochemical process of germination were studied in Dracocephalum kotschyi Boiss. seeds. The seeds were pretreated with green algae Spirulina platensis, Chlorella vulgaris and Dunaliella bardawil or D. IR-1 (Isolated from Gave-Khooni-salt marsh) and modified Johnson nutrient med...
Klasea is a taxonomically complex genus in which there are many problems, mostly with Klasea kotschyi and Klasea hakkiarica. It is challenging to differentiate the genera based on morphological characters alone. Revision studies performed on the basis of molecular data obtained from studies conducted in recent years have made the phylogenetic relationships and systematic positions of the taxa m...
Four LMW-m and one novel chimeric (between LMW-i and LMW-m types) low-molecular-weight glutenin subunit (LMW-GS) genes from Aegilops neglecta (UUMM), Ae. kotschyi (UUSS), and Ae. juvenalis (DDMMUU) were isolated and characterized. Sequence structures showed that the 4 LMW-m-type genes, assigned to the M genome of Ae. neglecta, displayed a high homology with those from hexaploid common wheat. Th...
Starting from racemic naringenin ((±)-1), a mixture of dracocephin A stereoisomers 6-(2"-pyrrolidinone-5"-yl)naringenin (±)-2a-d and its regioisomer, dracocephin B 8-(2"-pyrrolidinone-5"-yl)naringenin (±)-3a-d originally isolated from Dracocephalum rupestre, have been synthesized in a one-pot reaction. The separation of 2a-d and 3a-d was achieved by preparative HPLC. The four stereoisomers of e...
Plants often grow in clusters of various sizes and have a variable number of flowers per inflorescence. This small-scale spatial clustering affects insect foraging strategies and plant reproductive success. In our study, we aimed to determine how visitation rate and foraging behaviour of pollinators depend on the number of flowers per plant and on the size of clusters of multiple plants using D...
جنس کلشیکوم (colchicum l.) به علت تولید کلشی سین شناخته شده است و چندین گونه از آن در نقاط مختلف ایران به صورت خودرو رشد می کنند. سطوح کلشی سین در طی رشد و نمو و در گونه های مختلف، متغیر است. به منظور تعیین میزان کلشی سین و درصد وزن خشک، طی مراحل مختلف نموی در دو گونه سورنجان بومی ایران (colchicum kotschyi boiss. و c. robustum stefanov)، کورم ها و بذرهای هر دو گونه طی فصول مختلف (بهار، تابستان،...
Turkey is one of the most important centers of diversity for the genus Achillea L. in the world. Keeping in mind the immense medicinal importance of phenols, in this study, three species growing in Turkey, A. coarctata Poir. (AC), A. kotschyi Boiss. subsp. kotschyi (AK) and A. lycaonica Boiss. & Heldr. (AL) were evaluated for their phenolic compositions, total phenolic contents (TPC), antio...
Objective(s): The aim of this study was to evaluate the antidiabetic potential Pseudocedrela kotschyi leaf decoction by making a comparison between extracts harvested over three months.
 Design: This is done through few experiences. After quantification total polyphenols folin-Ciocalteu reagent method, antioxidant activities were tested with ABTS, DPPH and FRAP essays. Then, glucose oxidas...
