چکیده: در این پژوهش ما جنس podonosma را احیا داده می شود و اعضای این جنس را به منظور تعیین روابط خویشاوندی به وسیله ی 85 صفت کمی و کیفی زایشی و رویشی با استفاده از نرم افزار mvsp مورد آنالیز قرار دادیم؛ گروه های فنتیکی حاصل از آنالیز pco داده های ریخت شناسی اعضای این جنس را به 6 گروه تقسیم کرد که عمده تفاوت این گروه ها ناشی از شکل برگ ها، گل آذین و پوشش کرکی می باشد. اعضای بخش asterotricha در...
جنس anchusa از علف های هرز خانواده boraginaceae است که یک گیاه دارویی و اصیل است که از سال ها قبل به نام گل گاوزبان در درمان بیماری ها مورد استفاده قرار می گرفته است. این جنس در ایران دارای 4 گونه می باشد. در این پژوهش که اولین بررسی در خصوص گونه های خودروی anchusa در ایران است، بررسی بیوسیستماتیکی گونه ها با استفاده از مطالعات ریخت شناسی، تشریحی و سیتوژنتیکی با تکیه بر روش های تاکسونومی عددی ش...
(Morphology and histochemistry of glandular trichomes of Cordia verbenacea DC. (Boraginaceae) leaves). The objective of this work was to study, using light and fluorescence microscopy and scanning electron microscopy, the morphology and secretory products of glandular trichomes of Cordia verbenacea DC. (Boraginaceae), known as ‘baleeira’, a species used in folk medicine as anti-inflammatory, an...
The UHPLC-QToF-MS analysis of pyrrolizidine alkaloids (PAs) from various parts of 37 botanicals and 7 products was performed. A separation by LC was achieved using a reversed-phase column and a gradient of water/acetonitrile each containing formic acid as the mobile phase. MS-MS detection was used because of its high selectivity, and ability to provide structural information. Free base and N-ox...
The availability of next-generation sequencing (NGS) technology for nonmodel organisms in prime ecological scenarios has revolutionized evolutionary biology (Egan et al., 2012). An exciting prospect of NGS is the potential to improve our understanding of the genetic basis of processes such as adaptation and speciation (Stapley et al. Volcanic oceanic islands have long served as model systems fo...
A new species of Onosma L. (Boraginaceae: Lithospermeae), from the Hakkari province eastern Turkey, is described and illustrated. The endemic distributed in a narrow area Sat Mountains. Taxonomically closest relative satensis sp. nov. O. polioxantha Rech. f. which also occurs Turkey. In addition, it primarily distinguished by its navicular leaves, longer reticulate cauline pedicels calyx, dense...
Putative activity of hydroalcoholic and aqueous infusion extracts of Echium amoenum L. was investigated in mice using the rotarod model of motor coordination and the elevated plus maze model of anxiety. The extracts were administered intraperitonealy (i.p.) once, one hour before performing the tests. Preliminary phytochemical study of the plant, with standard procedures, showed that it contains...
UNLABELLED Botanical seed oils reduce the generation of leukotrienes in patients with asthma. Our objective was to determine the efficacy of a botanical seed oil combination against airflow obstruction in asthma, and to determine the pharmacogenomic effect of the leukotriene C4 synthase (LTC4S) polymorphism A-444C. We conducted a randomized, double-blind, placebo-controlled, cross-over clinical...
