Proper thin-layer chromatographic system was developed for the determination of tetrandrine and sinomenine in Menispermum dauricum D. C which grew in Qinba mountains by micellar fluorometry. The content, detection limit and recovery obtained are 9. 94×10-12 g/g, 3. 5×10-12 g/mL,93. 75% for tetrandrine, and 1. 07 × 10-3 g/g, 5. 85 × 10-11 g/mL, 97. 23% for sinomenine, respectively.
