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%.

Achillea tenuifolia Lam. (Asteraceae) afforded a methanolic extract from which after fractionation in solvents with different polarities, two known flavones 3', 5- dihydroxy- 4', 6, 7- trimethoxy flavone (eupatorine, compound 3), 5- hydroxy- 3',4', 6, 7- tetramethoxyflavone (compound 4), besides stearic acid (compound 1), lupeol (compound 2), daucosterol (β- sitosterol 3-O- β- D- glucopyranosid...

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...

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 composition of essential oil isolated from achillea eriophora, achillea millefolium, achillea biebersteinii and achillea tenuifolia growing wild in the south west of iran, was analyzed.  a. eriophora, a. millefolium and a. tenuifolia essential oils were characterized by sabinene, 1, 8-cineole, terpinene-4-ol, ά –bisabolol, p-cymene, β-pinene and α-pinene. the a. biebersteinii essential oil ...
