An optimized protocol for anthraquinones isolation from Rhamnus frangula L. Issue 3 (1st February 2018) - Gonçalves, Renato Sonchini
Abstract: Different from works described in the literature, which use expansive analytical methods to separation of anthraquinones derivatives (AQs), this communication reported a simple and inexpensive methodology to get them. In this way, the expensive commercial AQs: Chrysophanol, physcione and emodine were extracted from plant material ( Rhamnus frangula L.) and isolated by classical column chromatography technique under optimised binary mobile phase gradients (CHCl3 : AcOEt( a ), a = 1 to 5%) in excellent yields.
