Abstract
By a systematic investigation of the extractives of the bark of Phebalium nudum Hook twenty-one compounds have been isolated. Seventeen have been identified as d-citronellal, geranial, neral, acetic, isovaleric, palmitic and cinnamic acids, isoeugenol, β-sitosterol, α-terpineol, dictamnine γ-fagarine, evolitrine, skimmianine, kokusaginine, 9-hydroxy-4-methoxyfurano(3,2- g)benzopyran-7-one, and ellagic acid. The remaining four substances were obtained in a crystalline state, but in insufficient quantity for complete investigation. Two are new and appear to be of the coumarin type; they have been named phebalin and phebalarin. A partial structure has been proposed for phebalarin. The other two are aliphatic. The presence of at least a further ten phenolic substances has been shown by paper chromatography.
