Abstract:ObjectiveTo study the chemical constituents from Shuanglhuanglian injection. MethodsShuanghuanglian injection was manufactured according to Chinese Pharmacopoeia (2005), and separated with column chromatography. Structures of the compounds were identified by their physical-chemical character and spectral analysis.ResultsSix compounds were isolated from Shuanghuanglian Injection. They were baicalin (Ⅰ),chrysophenol (Ⅱ),chlorogenic acid (Ⅲ),rutin (Ⅳ),isopimpinellin (Ⅴ) and quercetin (Ⅵ).ConclusionCompoundsⅡ,Ⅳ,Ⅴ and Ⅵ were isolated from Shuanghuanglian injection for the first time.
Key words:Shuanghuanglian injection; Chemical constituents; Isolation and identification
