To study the chemical constituents from Melicope ptelefolia. Several chromatographic methods were applied to isolate and purify compounds. Their structures were identified on the basis of physicochemical properties and spectroscopic data. Seven compounds were isolated and elucidated as n-octadecanyl palmitate

To investigate the chemical constituents of Kalopanax septemlobus. Chromatographic techniques including silica gel, gel, semi-preparative HPLC and PTLC as well as recrystallization were employed in the isolation and purification, and the structures were elucidated by spectral analysis and physical and

To study the chemical constituents of the root tube from Pteroxygonum giraldii. Column chromatography and spectral analysis were used to isolate and identify the constituents. Ten compounds were isolated and identified as beta-sitosterol (I), beta-sitosterol glucoside (II), 4', 5,5', 7-tetrahydroxy-3'-methoxy-3'-O-alpha-L-arabinopyranosyl
