| Abstract: | The simple and specific method - uniform design, was described for selection of optimalcomposition of the solvent system used in TLC analysis of Shufen Ghuoluo Wan and Jiufen San Amethod for the TLC-densitometric determination of strychnine and brucine has been established.The sample solutions and those of the mixed authentic alkaloids were spotted on a basic silica andgot GF_(254) plate and was developed by chloroform-methanol-ammonia spiris (0.9:5.8:1.5). Thespots were scanned with a Shimadzu Dual-wavelength TLC Scanner CS-930 at w 1=254 nm and w2=325 nm by reflection mode and zig-zag scanning. Satisfactory results were obtained |
