Title The Study On Extraction Of Indigowoad root effective component
Abstract
Indigowoad root is one kind of important medicinal plant, Indigowoad root contains inldirubin,indigo, the polysaccharide,β- sitosterol, γ- sitosterol, the arginine, the glutanic acid and so on. each kind of amino acid as well as sinigrin uridine the glucoside, hypoxanthine, uracil, salicylic acid and carrot daucosterol. The therapeutic action active constituents mainly exist in inldirubin,indigo and the polysaccharide.
Chinese medicine indigowoad root is the raw material. In this study separately through single factor experiment and orthogonal test, The best technological parameter of indirubin indigo was determined. the content the of the indirubin and indigo in indigowoad root by the RP- HPLC. The result indicated, The orthogonal test definite optimum extraction technological parameter is follow: raw material for medicine granularity 60 items, extraction time 4 hours, ethyl alcohol volume fraction 75%. Extraction resulting of the indigo and indirubin in rate is highest.
