The Study On The Separation, Extraction And The Relevant Nature Of Chuanxiong (Ligusticum Chuangxiong Hort.) Saccharide Substance

Chinese medicinal herb, Chuanxiong (Ligusticum Chuangxiong Hort.) isoriginally recorded by 'Shennong bencao jing'. It is a kind of perennial herb whosefamily is Umbelliferae, and is one of commonly used principal drug in Chinesemedicinal formulae. In classification of Chinese medicinal hers, it belongs to thegroup of promoting blood circulation to arrest pain,and possesses functions ofremoving blood stasis, eliminating wind and stopping pain,nourishing the bloodand circulate qi as well. For compatibility in prescriptions of promoting blood,Chuanxiong(Ligusticum Chuangxiong Hort.)can strengthen the action of circulatingblood and eliminating stasis;on the other hand, for compatibility with antanemic,itcan smooth qi and blood without stagnant. In China, the resource of Chuanxiong(Ligusticum Chuangxiong Hort.) is very rich and widespread,which main area ofproduction is Sichuan province, Guan County. It also has man-made cultivation innorth-east area. Now it has a mount of report concerning chemical compositionresearch of Chuanxiong (Ligusticum Chuangxiong Hort.), but the report regarding tochuangxiong polycose research haven't been seen yet.Having been crashed for dry rhizome of Chuanxiong (Ligusticum ChuangxiongHort.) in common temperature, it got total sugar solution of Chuanxiong (LigusticumChuangxiong Hort.) by extracting and undoing liposolubility materials with ligarine,correcting aetherolea composition with alcoholic solution, soaking with cold water,diffusing with heat water, and condensing with water-bath. In term with the propertythat polycose never dissolve in 95% alcoholic solution,it precipitate crude polycose.After anhydration by absolute alcohol, absolute ether, and acetone, andvacuumdehydration,the crude polycose powder of Chuanxiong(Ligusticum ChuangxiongHort.)has been made. Through weighing calculation,the yield of crude polycose was6.7%.By decoctions of carbolic acid method , sulphuric acid method, and anthronemehtod the components of polycose was 4.11%;by decoctions of filter paperchromatography, thin-layer chromatography(TLC), and vapor phase chromatography,polycose is composed by Ara, Gal and Glc,and its molar ratio was 1:1.4:7.9 . Bydecoction of Kjeldah method protein content in polycose of Chuanxiong (LigusticumChuangxiong Hort.) was 12.37%.
