in many field observation, ecological equipment, phenology and ethnopharmacological data of achillea millefolium l. and a. micrantha wild. were studied. the inflorescences of plants were collected in different locations of golestan province: chaharbagh (2000 m) and dozan (2200 m) respectively. essential oils were obtained by steam distillation (clevenger) and analyzed by gas chromatography-mass...

Mathematical, fuzzy logic and artificial neural network modeling of extraction kinetics essential oil from aerial parts yarrow (Achillea millefolium L.) using ohmic-assisted hydrodistillation

Achillea millefolium and Achillea ptarmica are both plants belonging to the Asteracea family and are traditionally used for their medicinal properties. It has already been shown that some N-alkylamides (NAAs) are responsible for these pharmacological actions. Therefore, in the present study, the NAA content of the two plants was analytically characterised. Different extracts were prepared from ...

In this study, a new chromosome number for Iranian yarrow (Achillea millefolium L.) accessions was reported. Cytological analyses on four Achillea millefolium accessions, indicated that two accessions were diploids (2n=2x=18) and two tetraploids (2n=4x=36). Cluster analysis based on chromosomal characteristics and karyotype asymmetry, categorized the four accessions separated into two groups. I...

Fifteen yarrow populations from different species Achillea millefolium L., A. biebersteinii L. and A. nobilis, from different geographical areas of Iran were studied using 24 morphological traits and peroxidase profiles. Comparison of mean values of different phenotypic traits show A. millefolium and A. biebersteinii L. had higher plant height and crown diameter; however, A. nobilis had higher ...
