Common NameGentiakochianin
DescriptionSwertianin, also known as gentiakochianin, belongs to the class of organic compounds known as xanthones. These are polycyclic aromatic compounds containing a xanthene moiety conjugated to a ketone group at carbon 9. Xanthene is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring. Gentiakochianin is found in Chironia krebsii, Gentiana acaulis, Gentiana bavarica, Gentiana brachyphalla, Gentiana brachyphylla, Gentiana japonica, Gentiana kochiana , Gentiana lactea, Gentiana nivalis, Gentiana ramosa, Gentiana strictiflora, Gentiana verna, Gentianopsis barbata, Orphium frutescens, Swertia angustifolia , Swertia calycina, Swertia chirata , Swertia ciliata, Swertia dilatata, Swertia erythrosticata, Swertia fasciculata, Swertia gracilescens, Swertia hookeri, Swertia japonica , Swertia macrosperma, Swertia nervosa, Swertia paniculata , Swertia perennis, Swertia perfoliata, Swertia pseudochinensis, Swertia punicea, Swertia punicea var.lutescens, Swertia purpurescens, Swertia racemosa , Swertia speciosa and Swertia thomsonii. Gentiakochianin was first documented in 2004 (PMID: 15807240). Swertianin is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 21985644) (PMID: 24378350) (PMID: 24877112).
