Achillea tenuifolia Lam. (Asteraceae) afforded a dichloromethane fraction from which three known compounds β-sitosterol (compound1), 5-hydroxy, 4',6,7- trimethoxy flavone (salvigenin compound 2), and methyl-gallate (compound 3) were isolated for the first time. The structure of isolated compounds was elucidated by different spectroscopic methods. Applying the molar-ratio method, the complexatio...

The water-distilled essential oil from dried aerial parts of achillea tenuifolia Lam. Was analysed by GC and CG/MS. 48 Components were characterized representing 88% of the total oil. Camphor (18%), 1,8-cineole + limonene (9%) and spathulenol (7%) were the major constituents of the oil obtained in a yield of 0.23%.

The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

chromosome counting was performed in nine populations of achillea tenuifolia lam and eight populations of a. bieberestinii afan (asteraceae) collected from hamedan and kermanshah provinces in the west of iran. chromosome numbers in both species varied from 2n=2x=18 to 2n=4x=36. some populations of both species showed (2n=4x=36) chromosome number that is the first report as polyploidy levels. an...

The genus Achillea (Asteraceae) consists of important medicinal species, growing wildly in Iran, of which A. tenuifolia is found in Iran-o-Turan regions. Regarding the traditional use of Achillea species for treatment of diabetes and also lack of information on phyto-constituents of A. tenuifolia underground parts, in this study the results of anti-diabetic activity of this plant have been repo...
