Sexual hybrids of Tanacetum: biochemical, cytological and pharmacological characterization

Variation of chromosome numbers in Tanacetum parthenium Schultz Bip. (Asteraceae) in Iran

“…1J). These findings, about the above-mentioned populations, are accordance with several previously reported data (Ferakova 1976(Ferakova , 1978Strid andFranze´n 1981, 1983;Kuzmanov et al 1986;Bruhl 1990;Pastor et al1990;Baltisberger 1993;Dempsey et al 1994;Brown et al 1999;Chehregani and Hajisadeghian 2009) and are different from our prior report (Chehregani and Mehanfar 2008) about several populations collected in Zanjan Province.…”

“…Several counts of chromosomes have been carried out on different wild population of Tanacetum parthenium, giving the chromosome number of 2n=2x=18 (Ferakova 1976(Ferakova , 1978Strid andFranzen 1981, 1983;Kuzmanov et al 1986;Bruhl 1990;Pastor et al 1990;Baltisberger 1993;Dempsey et al 1994;Brown et al 1999;Chehregani and Hajisadeghian 2009). Our bibliographical studies indicated that only diploid chromosome number of 2n=18 has been reported for this species.…”

“…Tanacetum L. formerly placed in Pyrethrum Zinn, is a large, poorly defined, classification group in the Asteraceae containing polymorphic species, many of which have applications as herbal medicines (Brown et al 1999). Tanacetum is one of the largest genera of the family containing 250 to 500 taxa depending on the opinions of the authors who have studied the genus (Mc Arthur and Plummer 1978;Mabberley 1990;Ling 1991 a, b;1995 a, b;Bremer and Humphries 1993;Kadereit and Jeffrey 2007;Funk et al 2009 ).…”

Variation of chromosome numbers in 14 populations of Tanacetum parthenium and eight populations of T. polycephalum in Hamedan Province, Iran

“…The chromosome numbers obtained for these populations support the earliar reports (Strid and Franzen 1983;Kuzmanov et al 1986;Pastor et al 1990;Bruhl 1990;Baltisberger 1993;Dempsey & Bailey 1994;Brown et al 1999;Carr et al 1999;Strid A. and Franzen R., 1981;El-Twab M. H. A. and Kondo K., 2001;Ferakova V., 1976;Ferakova V., 1978;Zhmyleva., 2006 ). In one population, chromosome number 2n=6x=54 was observed, That this count is reported for first time (Fig.1N).…”

“…Several studies have also reported that feverfew is effective as an herbal remedy for arthritis, pain, and migraine (Heptinstall et al 1985;Jain and Kulkarni 1999). Feverfew has become widely established in the United Kingdom, as it has throughout mainland Europe, North and South America and northern Africa (Abad et al 19995).Some caryological studies has been performed on this species (Strid and Franzen 1983;Kuzmanov et al 1986;Pastor et al 1990;Bruhl 1990;Baltisberger 1993;Dempsey and Bailey 1994;Brown et al 1999).
