The components extracted by petroleum ether from a Chinese herb - Rabdosina Serra(Maxim.) Hara were separated and detectedby GAS CHROMATOGRAPH ELECTRON IONIZATION DETECTOR. Their structures were searched and identified by HPNBS75K data base and proved that there are fifteen known compounds in this herb.
Methods for separating 1-(2,4-Dichlorophenyl) 4, 4-dimethyl 1-2(1,2,4-triazol-l-yl) 1-penten-3-ol isomers and D,L-tryptophan enantiomers using HPTLC and TLC were investigated. The effects on Separation made by different nonchiral mobile phase, chiral mobile phase and two different shapes of plates were studied. Useful separation was obtained forstereoisomers, and the resolution of D, L-tryptophan was good by using chiral mobile phase additive(D-quinia).
