Study on Quality Standard of Jinyou Tankeqing Tablets / 中药新药与临床药理

ABSTRACT

Objective To study the quality standard of Jinyou Tankeqing Tablets (JTT). Methods Total flavonoids in JTT were identified by TLC. Naringin content in JTT was determined by HPLC. Results The relevant spots of total flavonoids in JTT can be identified by TLC. The content of naringin in JTT can be determined by HPLC. The linearity of naringin was good in the range of 2～20 ?g (r= 0.999 9). The average recovery of naringin was 101.29 %with RSD = 2.58 %. Conclusion The established quality standard is simple,feasible and repeatable,and can be used for the quality supervisory of JTT.
