ABSTRACT

OBJECTIVE:

To establish the quality standard for Embelia laeta.

METHODS:

TLC was adopted for the qualitative identification. HPLC was adopted for the content determination of embelinthe column was Waters C18 with mobile phase consisted of methanol-5%methanoic acid(90∶10,V/V)at a flow rate of 0.9 ml/min,the detection wavelength was 288 nm,the column tem-perature was 40 ℃,nd the injection volume was 10 μl.

RESULTS:

The TLC of E. laeta showed clear spots and good separation. The linear range of embelin was 4.012-40.12 μg/ml(r=0.999 4);RSDs of precision,stability and reproducibility tests were lower than 2%;recovery was 96.54%-99.57%(RSD=1.20%,n=6).

CONCLUSIONS:

The established standard can be used for the quality control of E. laeta.
