Fragrant species of the genus Salvia have been attributed many medicinal properties, which include anticancer activity. In the present study, cytotoxic properties of total methanol extract of Salvia chloroleuca Rech. f. & Aellen and its fractions were investigated on MCF-7, a breast carcinoma cell line. Malignant and non-malignant cells were cultured in RPMI medium and incubated with different ...

objectives this study was designed to determine the chemical composition, in vitro antioxidant activity, and total phenol content of various extracts of s. chloroleuca. materials and methods dried aerial parts of the plant were crushed, then sequentially extracted with n-hexane, ethyl acetate, and methanol. the fractions of s. chloroleuca were subjected to silica gel column chromatography and s...

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

We characterized the in...

two flavones, ladanein and 6-hydroxy-5,7,4′-trimethoxyflavone and one labdane-typediterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract ofthe aerial parts of salvia sharifii. the compounds were purified using several chromatographicmethods. structural elucidation of the compounds was performed using their 1h and 13c-nmrdata, ei mass and uv spectral data. the co...

The classical r-matrices with carriers gc containing the Borel subalgebra b(g) of simple Lie algebra g are studied. Using the graphical presentation of the dual Lie algebra g(r) we show that such solutions rech of the CYBE always exist. To obtain the explicit form of rech we find the dual coordinates in which the adjoint action of gc can be reduced. This gives us the detailed structure of the J...
