title: Phebaclavin I, a novel 3-prenylated coumarin, and trichoclin acetate, a new natural furocoumarin, from the aerial parts of Phebalium aff. tuberculosum (Rutaceae).
abstract: Phebaclavin I, a novel 3-prenylated coumarin, was isolated from the aerial parts of Phebalium aff. tuberculosum (Rutaceae) together with five known related compounds, Phebaclavin A, B, D, G, H. The structure of phebaclavin I was established by spectroscopic methods. Several other known coumarins were obtained, including trichoclin acetate, a furocoumarin isolated for the first time from a natural source, but previously described from acetylation of trichoclin.
