The ethyl acetate partition of dried methanolic extract of aerial parts of Euphorbia microsciadia (Euphorbiaceae) afforded three pentacyclic triterpenes, betulinic acid (1) from lupane type, oleanolic acid (2) from oleane type and ursolic acid (3) from ursane type triterpenes that are reported for the first time in this plant. These three compounds were structurally compared through their mass ...

Background: Breast cancer is the most prevalent malignancy among women in the worldwide and the outbreak in Iranian women is growing. Iranian patients with breast cancer are younger than their Western counterparts. Dracocephalum kotschyi is a wild-growing flowering plant belonging to the family Labiatae and found in Iran. This plant has been applied in Iran folk medicine. The aim of this study ...

The cytotoxic chloroform fraction of Euphorbia aellenii afforded two cycloartane type triterpenes — cycloart-25-en-3,24-diol (1) and 24-methylene-cycloartan-3-ol (2) — for the first time from this plant. Preparation of cycloartane derivatives, 3, 24-O-diacetyl-cycloart-25-en as compound 3 and 3-O-acetyl-24-methylene-cycloartan (4) were conducted by acetylating of 1 and 2, respectively. The ...

Ferulago W. Koch. (Apiaceae) genus is represented by approximately 50 taxa throughout the world. Ferulago species are known as “Çakşır” or “Çağşır” in Turkey and mostly known for their aphrodisiac effects. However recent reports emphasize the activity of various Ferulago species against cancer, as well. The aim of this study was to investigate the effect of lyophilized extract of F. mughlea Peş...

objective: osteoporosis or silent disease is a major bone disorder in elderly women in current century. estrogen has an important role in osteogenesis and prevention of bone fractures. hormone replacement therapy (hrt) is usually accompanied by such effects as breast and ovary cancers. thus, there is an increasing demand for replacement with plant phytoestrogens. this study is focused on determ...

Plants generate cells and organs throughout their life cycle. Plant cell proliferation relates to the activity of dividing meristematic cells, which subsequently differentiate in a position- and lineage-dependent manner. The events underlying the regulation of cell division and further differentiation processes are under tight control of both intrinsic and environmental parameters. Among the in...
