摘要
目的：测定维药野胡萝卜籽中多糖的含量。方法：经苯酚──浓硫酸显色应用分光光度法于４９０ｎｍ处测定吸收率，结果：其多糖含量为２３．１２ｍｇ／ｇ（生药），得回归方程为Ａ＝０．０５９１＋０．０４２８×Ｃ，ｒ＝０．９９９０，方法简便，结果稳定。
Object:The determination of polysaccharides in fructus carotae is made by a simple and precise method of phenol-sulphurie acid. Approach: Based on the information of wavelength of 490um by spectrophotometry,the regressive equation is A=0.00591+0. 0428×C,r= 0. 9990,mean value of recovery rate is 100. 8% (n=5), RSD=1.54% (n=5). Results:the content of polysaccharide is 23.12mg/g.
