Purification of Sesquiterpenes from Saussurea LappaRoots by High Speed Counter Current Chromatography
Sesquiterpenes lactones including costunolide and dehydrocostus lactone, were isolated from Saussurea lappa roots, which had exhibited a wide range of biological activities such as anti-cancer, anti-inflammatory, antiulcer, and immunomodulatory activities. High-speed counter-current chromatography (HSCCC) was applied for the rapid preparative isolation of sesquiterpenes lactones from <...

متن کاملHigh Speed Full Swing Current Mode BiCMOS Logical Operators
In this paper the design of a new high-speed current mode BiCMOS logic circuits isproposed. By altering the threshold detector circuit of the conventional current mode logic circuitsand applying the multiple value logic (MVL) approach the number of transistors in basic logicoperators are significantly reduced and hence a reduction of chip area and power dissipation as wellas an increase in spee...
متن کاملContinuous Current Oscillation Electropolishing and Applications to Half-cells
A method to electropolish niobium with continuous current oscillation is introduced. The current continuously oscillates for as long as 3 hours. The key is to maintain continuous agitation of the acid mixture. A niobium surface treated by this method has suppressed grain boundaries and a lower hydrogen content. The method has been used to electropolish L-band half-cells. The test results of a 1...
