[Isolation of the chemical constituents from Shuanghuanglian injection and their structural identification].
OBJECTIVE
To isolate and identify the chemical constituents of Shuanghuanglian injection.


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


CONCLUSIONS
Seven 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.
