Two anthraquinone compounds from the whole plants of Hedyotis corymbosa

Abstract

Hedyotis corymbosa from the Rubiaceae family, widely distributed in tropical regions of Asia. Based on the traditional uses, researchers provided substantial scientific evidence revealing the beneficial impact of this plant highlighting its anticancer, hepatoprotective, antiulcer, antioxidant, anti-malarial, antibacterial and antifungal activities. This study aims to screen and identify anthraquinone from the methanol extract of whole plant H. corymbosa. The Anthraquinone was further fractionated and isolated using chromatographic techniques to obtain the purity of compounds. The anthraquinone structure was determined using spectroscopic analysis especially the Nuclear Magnetic Resonance (NMR) and Mass Spectrum (MS).
