Therefore, as part of our continuing search for new AR inhibitors and antioxidants from natural products, we were to investigate the antioxidant and AR inhibitory effects of the dried stem bark of MA and isolate its active components using high-speed countercurrent chromatography (HSCCC) and Sephadex LH-20 column chromatography guided by an offline HPLCABTS assay and HPLC microfractionation AR assay.
For the purification of anthocyanins diverse analytical techniques have been proposed, from solid phase extractions (SPE) [9-11] to the use of chromatographic techniques, such as countercurrent chromatography (CCC) [12], medium pressure liquid chromatography (MPLC) [13], and high performance liquid chromatography (HPLC) [14-19].
