the essential oil from the aerial parts ofjurinea leptoloba dc., collected from shiraz (south of iran), was investigated for total phenolic content (tpc), antioxidant and cytotoxic effects. tpc of j. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg gae/mg oil) using the folin-ciocalteau assay. the ferric reducing power of the oil was determined 0.117 ± 0.0...

چکیده سرطان دهانه رحم دومین سرطان شایع خانم­ها در سراسر جهان است. تاکنون گیاهان زیادی با خاصیت ضد سرطانی شناسایی شده اند. جنس Jurinea (قبیلۀ Cynareae، زیر شاخۀ Carduinae) دارای 250 گونه می­باشد. در این تحقیق گیاه Jurinea leptoloba DC. از خانوادهCompositae  در مرداد ماه سال 1391 از جنوب شیراز جمع‌آوری و عصارۀ چربی­زدایی شدۀ آن از نظر محتوای فلاونوئیدی کل و خواص سمیت سلولی مورد ارزیابی قرار گرفت....

The current investigations suggest the segregation of Jurinea cartilaginea from Jurinea, and its placement among Centaureinae. Molecular studies, based on the nuclear ribosomal internal transcribed spacers (nrITS), chromosome number data and pollen morphology, support the morphological results. Based on these results, J. cartilaginea is related to and, therefore, transferred to the genus Karvan...

Eighteen taxa of the genus Jurinea Cass. growing naturally in Turkey were classified by numerical taxonomic analysis. Morphological and palynological characters of each individual were measured and quantified on the basis of 51 traits. Ten plants were chosen randomly for the measurements of metric characters related to the external morphology of the taxa and the average values used for statisti...

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...

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...
