【摘要】 采用高效液相色谱法,使用BondapakC18柱和紫外可变波长检测器,以甲醇+水为流动相,用外标法对2,3-二氢-2,7-二甲基苯并呋喃-6-羧酸有效成分进行分离和检测。本方法标准偏差≤0.4,变异系数小于0.4%,平均回收率为99.86%。更多还原

【Abstract】 Separation and quantitative determination of 2,3-dihydro-2,7-dimethylbenzofuranyl-6-formic acid wasdone using HPLC with a Bondapak C18 column, a variable wavelength UV detector, methanol-water as the mobilephase, and an external standard. Standard deviation was ≤ 0.4, coefficient of variation was < 0.4%, and averagerecovery was 99.86%.更多还原
