The extract also contained, among other products chrysophanol (1,8-dihydroxy-3-methylanthraquinone), physcion (1,8-dihydroxy-3-methyl-6-methoxyanthraquinone), aloe-emodin (3-carbinol-1,8-dihydroxyanthraquinone), lunatin (3-methoxy-1,6,8-trihydroxyanthraquinone), emodin (6-methyl-1,3,8-trihydroxyanthraquinone), and chrysophanol-10,10'-bianthrone.^[1]
