The compound 7,4'-dihydroxy-5-methoxyflavylium (dracoflavylium) was identified as the major red colorant in samples of the resin "dragon's blood", extracted from the tree Dracaena draco. The complex network of reversible chemical reactions that dracoflavylium undergoes in aqueous solution is fully described; for the first time, all the equilibrium constants that enable a complete characterisati...
The Afrotropical genera Gamia and Artitropa are only known to feed on species of Dracaena (Asparagaceae), and together with Leona lissa Evans, which may require a new genus, they are the only Afrotropical Hesperiidae that feed on this unusual host genus. We present partial life histories of two species of Gamia, 22 taxa of Artitropa (of at least 12 species, and including several undescribed tax...
Two new names, Dracaena neoparviflora and ridleyii are proposed as replacement names for the illegitimate D. parviflora Baker, nutans Ridl., respectively, latter being a later homonym of Willd. ex Schult.f., H.Jaeger. Lectotypes designated D.cambodiana, interrupta (synonym camerooniana), oddonii cantleyi, cinnabari, cuspidibracteata congoensis), haemanthoides, litoralis braunii), parviflora, no...
Chinese dragon's blood, the red resin of Dracaena cochinchinensis, one of the renowned traditional medicines, has been used to facilitate blood circulation and disperse blood stasis for thousands of years. Phenolic compounds are considered to be responsible for its main biological activities. In this study, total phenolic compounds of Chinese dragon's blood were made into capsule (Longxuetonglu...
