Differential signaling pathways involved in inducing ER-dependent activities by ginsenoside Rg1 and estren

To develop a simple and fast method for removing polyethylene glycol (PEG) and simultaneous determination of fives saponins, i.e. astragaloside IV, notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, and ginsenoside Rd in dripping pills made from Astragali Radix and Panax notoginseng.The extraction method was based on a liquid-liquid extraction using water-saturated n-butanol and the quantitative determination was based on ultra-performance...
