euphorbia macrostegia or persian wood spurge is one of the seventeen endemic plants of this genus in iran. three triterpenoids: 24-methylenecycloartan-3β-ol (1), butyrospermol (2) and cycloartenol (3) and three diglycerides: 1,2-di-o-α-linolenoyl-sn-glycerol (4), 1-o-linoleoyl-3-o-palmitoyl-sn-glycerol (5) and 1-o-α-linolenoyl-2-o-palmitoyl-sn-glycerol (6) were isolated from a hexane layer of m...

it has been reported that different species of euphorbia (euphorbiaceae) have antitumor activity. some reports also show that these plants have potential cytotoxic effect against different cell lines. in a program to screen the cytotoxicity of iranian native plants, euphorbia macroclada boiss. was collected, identified, and the cytotoxic activity of dichloromethane, ethylacetate, methanol extra...

Karyotypes of ten sections of genus Trigonella Linnaeus, 1753 (Fabaceae) from Turkey were investigated. Somatic chromosome numbers of examined species were determined as 2n=14 and 16. The karyotype analyses of the species were carried out and somatic chromosome numbers of Trigonella plicata Boiss., 1872, Trigonella brachycarpa (Fisch.) Moris, 1833, Trigonella rostrata Boiss., 1872, Trigonella l...

Euphorbia factor L2, a lathyrane diterpenoid isolated from caper euphorbia seed (the seeds of Euphorbia lathyris L.), has been traditionally applied to treat cancer. This article focuses on the cytotoxic activity of Euphorbia factor L2 against lung carcinoma A549 cells and the mechanism by which apoptosis is induced. We analyzed the cytotoxicity and related mechanism of Euphorbia factor L2 with...

We found several specimens of Tropidia connata, a mycoheterotrophic orchid from Borneo, with features which have never been described in any of the existing literature, namely subterranean tubers. We mainly focus on the importance of the subterranean structures in comparison with the mycoheterotrophic genus Kalimantanorchis from the tribe Tropidieae. This finding of the tuberous structure gives...

The chromosomes of 15 species of Iridaceae of the genera Alophia, Cipura, Eleutherine, Neomarica and Trimezia (subfamily Iridoideae) were examined after conventional Giemsa staining. The karyotypes of Alophia drummondii (2n = 14+1B, 28, 42 and 56), Cipura paludosa (2n = 14), C. xanthomelas (2n = 28) and Eleutherine bulbosa (2n = 12) were asymmetric; Neomarica candida, N. caerulea, N. humilis, N...
