Phenolics from Rhagadiolus stellatus (Asteraceae, Cichorieae)
Rhagadiolus stellatus Gaertn., a Mediterranean member of the Cichorieae tribe of the Asteraceae family used as a food plant, was analyzed for its spectrum of phenolic compounds. Kaempferol 3-O-β-glucoside 1, kaempferol 3-O-β-rutinoside (nicotiflorin) 2, quercetin 3-O-β-glucoside 3, and luteolin 4 were isolated from the n-butanol layer of a methanolic extract of whole plants of Rh. stellatus of ...
متن کاملPhenolics as Chemosystematic Markers in and for the Genus Crepis (Asteraceae, Cichorieae)
In contrast to the huge variety of sesquiterpene lactones reported, only a limited number of flavonoids and phenolic acids are known from the genus Crepis. Compounds detected in the course of this investigation encompass flavonoids luteolin, luteolin 7-O-glucoside, luteolin 7-O-gentiobioside, luteolin 7-Oglucuronide, and luteolin 4’-O-glucoside and caffeic acid derivatives chlorogenic acid, 3,5...
متن کاملMeiotic Studies in Some Species of Tribe Cichorieae (Asteraceae) from Western Himalayas
The present paper deals with meiotic studies in 15 species belonging to 6 genera of the tribe Cichorieae from various localities of Western Himalayas. The chromosome number has been reported for the first time in Hieracium crocatum (2n = 10) and Lactuca lessertiana (2n = 2x = 16). Further, intraspecific variability has been reported for the first time in H. umbellatum (2n = 2x = 10 and 2n = 6x ...
متن کاملTwo new mountainous species of Lactuca (Cichorieae, Asteraceae) from Iran, one presenting a new, possibly myrmecochorous achene variant
It is shown that the concept of the Iranian endemic Lactuca polyclada in the sense of both its original author Boissier and its current use actually admixes two entirely different species, as was first noted by Beauverd a hundred years ago but has been neglected by later workers. One is a putative relative of Lactuca rosularis, the other was recognised by Beauverd as a member of the genus Cicer...
متن کاملکاربرد مورفولوژی فندقه در رده بندی چند گونه از قاصدک (Asteraceae tribe Cichorieae) در ایران
میکرومورفولوژی هفده گونه متعلق به جنس قاصدک (تیره آفتابگردان) با استفاده از میکروسکوپ الکترونی مورد بررسی قرار گرفت. در این مطالعه دوازده صفت کمی و کیفی از قبیل طول، عرض و رنگ فندقه، نوع و اندازه تزئینات بدنه فندقه، طول منقار، طول و رنگ پاپوس بررسی شد. آنالیز خوشهای و آنالیز مولفه اصلی دادهها نشان داد که میکرومورفولوژی فندقه در تفکیک گونه‌ها از یکدیگر نقش مهمی داشته در حالیکه جداسازی در سطح ب...
