Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi....
سه گونه از cousinia. sect. cousinia به نام های cousinia hohenackeri ، c. chlorocephala و c. lomakini برای اولین بار، از استان آذربایجان گزارش می شوند. محل انتشار این گونه ها، در فلور ایرانیکا و فلور شوروی، ماوراء قفقاز، تالش و ارمنستان ذکر شده است. همچنین، گونه chlorocephala c. در فلور شوروی از شمال ایران نیز ذکر شده است که تاکنون نمونه ای از آن از ایران جمع آوری نگردیده است، بنابراین، در این م...
این دومین بخش از مجموعه مطالعات کروموزومی روی گیاهان خانواده asteraceae ایران است. در مطالعه حاضر 28 جمعیت متعلق به 25 گونه گزارش شده است. شرح مطالعات کروموزومی 11 گونه جدید است و گزارش کروموزومی گونه carduus seminudusبا گزارش قبلی تفاوت دارد. همچنین عدد پایه کروموزومی جنس grantia برای اولین بار گزارش می شود. شمارش کروموزومی 8 گونه دیگر برای فلور ایران جدید است. رفتار کروموزومی در تقسیم میوز بر...
Inceer, H. (2021). Lectotypification of two Boissier's names in Chamaemelum (Anthemideae, Asteraceae). Candollea 76: 259–260. In English, English abstract. Turkey appears to be a center diversity for the genus Tripleurospermum Sch. Bip. Asteraceae) with c. 32 species among 40 accepted genus. Two conoclinium Boiss. & Balansa and monticola A. Huet are lectotypified discussed. Received: May 5, 202...
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...
Plants from Asteraceae family are widely used as herbal medicines and food ingredients, especially in Asian area. Therefore, authentication and quality control of these different Asteraceae plants are important for ensuring consumers' safety and efficacy. In recent decades, electronic nose (E-nose) has been studied as an alternative approach. In this paper, we aim to develop a novel discriminat...
New combinations are provided in Distephanus for two species from Madagascar.
Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Asteraceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria...
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...
