جنس inula متعلق به تبار inuleae از تیره کاسنی دارای حدود 100 گونه در دنیا است. در بررسی حاضر ساختار تشریحی برگ در برش عرضی و اپیدرم از منظر سطحی مطالعه گردیده است. با استفاده از 21 صفت، جداسازی گونه ها انجام شده و کلیدی به منظور شناسایی گونه ها تهیه شده است. سپس مهم ترین صفات مانند نوع کرک، شکل اپیدرم در هر دو سطح، نوع روزنه از منظر سطحی و برش عرضی، تعداد دستجات آوندی، تعداد ردیف های پارانشیم ن...
Inula species are medicinal and aromatic plants used for folk medicine extensively. In this work, hydrodistilled essential oil of Inula graveolens (Linnaeus) Desf. analyzed by GC-MS which revealed that bornyl acetate was the major product (69.15%). Camphene was the second major compound (11.11%). Antiproliferative activity of the essential oil and bornyl acetate was investigated on HeLa (human ...
Inula grantioides (Boiss.) syn. /. cutchica Clarke is found in South West Pakistan, Karachi (Sindh), Kutch, Indus delta and Baluchistan. The plant is recommended for the treatment of asthma. This plant has not been subjected to chemical investiga tion so far. In the present paper we wish to report the isolation of two new flavones, grantionin 1 and grantioidinin 2 along with pluchidione 3, a k...
Eight sesquiterpene lactones were isolated from the roots of Inula helenium and flowers of I. japonica. Among them, isoalantolactone (3) and santamarine (6) exhibited significant growth inhibitory activities against gynecologic cancer cell lines, while others weakly inhibited the growth of the cell lines (IC50 < or = 100 microM). In addition, 3 significantly inhibited the tumour growth of S180 ...
Five new dimeric sesquiterpene lactones, neojaponicone A (1) and japonicones M-P (2-5) were isolated from the aerial part of Inula japonica. Neojaponicone A (1) has an unprecedented carbon skeleton with an unusual valerolactone system formed between a guaianolide and an eudesmane. The structure and absolute configuration of 1 were established by extensive analysis of spectroscopic data and comp...
