Common NameAloe emodin
DescriptionAloeemodin, also known as rhabarberone, belongs to the class of organic compounds known as anthraquinones. These are organic compounds containing either anthracene-9,10-quinone, 1,4-anthraquinone, or 1,2-anthraquinone. Thus, aloeemodin is considered to be an aromatic polyketide lipid molecule. Aloeemodin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Aloeemodin has been detected, but not quantified in, green vegetables. Aloe emodin is found in Aloe arborescens , Aloe berhana, Aloe castellorum, Aloe elgonica, Aloe ferox , Aloe marlothii , Aloe megalacantha, Aloe pulcherrima , Aloe rivae, Aloe spp. , Aloe striata, Aloe succotrina, Aloe turkanensis, Aloe barbadensis , Aloe vera var.chinensis , Asphodelus aestivus, Asphodelus albus, Asphodelus fistulosus, Asphodelus microcarpus , Berchemia floribunda , Callisia fragrans, Cassia acutifolia , Cassia angustifolia , Cassia grandis , Cassia javanica, Cassia mimosoides , Cassia occidentalis , Cassia senna , Cassia tora , Frangula alnus, Isatis indigotica , Kniphofia isoetifolia, Oroxylum indicum , Pheum palmatum, Picramnia antidesma , Picramnia hirsuta, Rhamnus alaternus , Rhamnus davurica, Rhamnus purshiana , Rhamnus purshianus bark, Rheum emodi , Rheum kialense, Rheum officinale , Rheum palmatum , Rheum rhabarbarum, Rheum spp., Rheum tanguticum , Rheum undulatum , Rumex cristatus, Rumex dentatus , Rumex patientia , Rumex scutatus , Selaginella delicatula, Senna alata, Senna alexandrina, Senna didymobotrya, Cassia obtusifolia , Senna petersiana, Senna reticulata, Spatholobus suberectus, Tectona grandis and Xanthorrhoea australis . Aloe emodin was first documented in 2013 (PMID: 22931417). This could make aloeemodin a potential biomarker for the consumption of these foods (PMID: 24685589) (PMID: 24707862).
