Objective To investigate the chemical constituents and cytotoxic activities of breast cancer in the roots of Euphorbia ebracteolata. Methods The chemical constituents were isolated and purified by various chromatographic techniques. The in vitro cytotoxic activities of breast cancer of the isolated compounds were studied by MTT method. Their structures were identified on the basis of spectroscopic analyses and physiochemical properties. Results Ten compounds were isolated from the roots of Euphorbia ebracteolata, and elucidated as 2,4-dihydroxy-6-methoxy-3-form yl-1-acetophenon (1),2,4-dihydroxy-6-methoxy- 3-methyl-1- acetophenon (2), ebracteolatain A (3),3,3'-diacetyl-4,4'-dimethoxy-2,2',6,6'-tetrahydroxy diphenylmethan (4), jolkinolide B (5), jolkinolide A (6), linoleic acid (7), fischeria A (8), β-amyrin acetate (9), nonadecanoic acid monoglyceride (10). Compound 3 showed cytotoxicity against MDA-MB-231 cell、Sum149 cell、MCF7 cell、ZR-75-1 cell、SKBr3 cell、BT474 cell with IC50 values of (6.69±0.128),(5.50±0.126),(5.50±0.126),(7.08±0.111),(8.64±0.197),(5.42±0.113)μmol/L,respectively. Compound 4 had no cytotoxicity on the above cancer cells. Conclusion Compounds 6,7,8,10 were firstly isolated from Euphorbia ebracteolata. Compound 3 showed significant cytotoxicity on breast cancer cells. [ABSTRACT FROM AUTHOR]

Objective To study the synthesis of dammarane-type triterpene derivatives by using Panaxadiol and Panaxatriol as starting materials and screen their cytotoxic activity in vitro. Methods The products derived from PCC oxidation and DDQ oxidation of panaxadiol and panaxatriol， were further oxidized with m-chloroperoxybenzoic acid (m-CPBA)， as a result， four ring opening products were obtained， which were subjected to in vitro cytotoxic activity screening with MTT method. Results Four ring-opening derivatives were prepared (Compound 2，4，6， 8) . Conclusion The four ring-opening derivatives are new compounds， and compound 2 and 4 show significant cytotoxicity against several cancer cell lines. [ABSTRACT FROM AUTHOR]

Objective To determine the concentration of eupatilin and arteanoflavone in A rtemisia anomala by high performance liquid chromatography (HPLC）. Methods A rtemisia anomala was extracted by ultrasonic for ６０ minutes with １０ times volume of methanol. The HPLC was performed on a SHISEIDO MG-C１８ column (３.０ mm × １００ mm, ３ μm）. The mobile phase was a mixture of acetonitrile (ACN) and ０. １％ formic acid (４０ ∶６０, V／V ）. The detection wavelength was ３５０ nm, the column temperature was ２５ ℃ and the injection volumn was ５ μl. Results Eupatilin and arteanoflavone were separated at baseline within １５min with good linearity. The method validation results show that the precisions, repeatability and stability were all in the normal range. The low, medium and high level recoveries of eupatilin were １００.２６％, ９９.５８％, １０２.２４％, and those of arteanoflavone were ９９.０９％, １０１.１２％, １０１.４３％, respectively. Conclusion The method was rapid, simple, reproductive and accurate. It can be used to control the quality of A rtemisia anomala. [ABSTRACT FROM AUTHOR]
