OBJECTIVETo isolate and identify the chemical constituents of Shuanghuanglian injection.

METHODSChromatography and spectral analysis were performed to isolate and identify the chemical constituents respectively.

RESULTS AND CONCLUSIONSeven compounds were isolated from Shuanghuanglian injection, including chlorogenic acid (I), caffeic acid (II), chrysophanol (III), physcion (IV), rutin (V), baicalein (VI) and glucose (VII). The compounds III, IV, V and VII were isolated and identified in Shuanghuanglian injection for the first time.
