Five compounds - chrysophanol, emodin, physcion, aloe-emodin and rhein - were isolated and identified spectroscopically (UV, IR and MS) and by comparison of the melting points with those reported for chrysophanol, emodin, physcion, aloe-emodin and rhein.
Five compounds were identified and assayed, namely aloe-emodin, chrysophanol, emodin, physcion and rhein.
The incorporation varied, chrysophanol being highest and with rhein much lower.
Anthraquinones were consistently eluted in the sequence, aloe-emodin, rhein, emodin, chrysophanol and physcion.
