Abstract

Purpose: In the present study two medicinal herbs Linum persicum and Euphorbia cheiradenia that are native to Iran were tested for their possible anticancer effect and induction of apoptosis on human tumor cell lines including leukemia cell lines. Methods: The effect of methanolic extracts of the herbs on the inhibition of cell proliferation was assessed by MTT colorimetric assay. K562 and Jurkat cell lines treated with the extracts were analyzed for the induction of apoptosis by flow cytometry using propidium iodide staining. DNA fragmentation analysis was performed. Results: Various concentrations of L. persicum and E. cheiradenia showed inhibitory effects on different cell lines. Two leukemic lines including K562 and Jurkat were the most sensitive cells for L. persicum with IC50 of 0.1 and 10 μg/ml, respectively. In the cultures of tumor cell lines treated with E. cheiradenia, the main inhibitory effects was for Jurkat cells with IC50 of 12.5 μg/ml. Results indicated a dose-dependent accumulation of cells in the sub-G1 phase. Study of internucleosomal DNA fragmentation showed a typical DNA laddering in agarose gels for both extracts. Conclusion: The present study showed cytotoxic activity of both herbs on tumor cell lines and suggests that this effect may in part be due to the induction of apoptosis in leukemic cells.

Abstract

Seven species not previously reported for Lebanon and one species re-located after 183 years are reported here after their discovery during an ex situ seed conservation project in the country (Bombycilaena erecta (L.) Smoljan., Centaurea diffusa Lam.; Hypochaeris radicata L.; Gypsophila perfoliata L.; Euphorbia cheiradenia Boiss. & Hohen.; Stachys setifera C.A.Mey.; Stachys zoharyana Eig and Plantago maritima L.).

Abstract

Three new diterpene esters, cheiradone (1), cheiradone A (2), and cheiradone B (3), were isolated from the aerial parts of Euphorbia cheiradenia, collected in Iran. The structures were determined using different spectroscopic methods, including 1D and 2D NMR and X-ray diffraction analysis.

Abstract

Eriophyoid mites infesting spurges (Euphorbiaceae) were surveyed in Kandovan and Govgan, southwest of East Azerbai-jan Province in Iran, during 2010 and 2011. Two new species are described and illustrated: Aculops seguieranae n. sp. from Euphorbia seguierana Necker and Euphorbia cheiradenia Boiss. et Hohen, and Aceria cheiradeniae n. sp. from E. cheiradenia. No damage symptoms were observed.
