本文叙述药片中共轭及酯化雌激素用高压正向分配层析的测定法。本法基于雌激素硫酸酯预先在硅藻士-水柱上分离,以盐酸-甲醇水解转化成游离酚式,再经醚基键合相(Permaphase ETH)层析柱分离后测定。最
This article describes the determination of conjugated and esterified estrogens in tablets using high-pressure positive fractionation chromatography. This method is based on the estrogen sulfate ester pre-mite disabilities - water column separation, hydrochloric acid - methanol hydrolysis into free phenol, and then by ether-based phase (Permaphase ETH) column separation and determination. most
