欧椴(Tilia cordata L.)的花含有广泛药用粘多糖,本文研究其主成分粘多糖的结构。取干生药的提取物经三氟乙酸(TFA)水解后可得3%的粗粘胶,再用二乙胺乙基(DEAE)纤维素分得5个不同的多糖组分。
The flower of Tilia cordata L. contains a wide range of medicinal mucopolysaccharides, and the structure of its main component mucopolysaccharide is studied in this paper. The extract of dried crude drug was hydrolyzed with trifluoroacetic acid (TFA) to obtain 3% coarse viscose, and then 5 different polysaccharide components were obtained from diethylaminoethyl (DEAE) cellulose.
