ABSTRACT

Objective To establish quality standard for Liangsang Diandiye. Method Radix et Rhizoma Notoginseng, Flos Carthami and Radix Salviae Miltiorrhiizae were identified by TLC. Ginsenoside Rg1 was determined by dual-wavelength TLC-scanning with 525 nm and 700 nm as the detective wavelength. Results Radix et Rhizoma Notoginseng, Flos Carthami and Radix Salviae Miltiorrhiizae can be identified by TLC. A good line relationship was noted at the range of 1.53～7.65 ?g Ginsenoside Rg1 (r =0.9991). The average recovery was 99.10%, and RSD was 0.27%. Conclusion The established method can be used for the quality control of Liangsang Diandiye.
