Abstract:Eight vilasinin-class limonoids, including the unusually chlorinated rubescins K–M (1–3), the 2,3-epoxylated rubescin N (4), and rubescins O–R (5–8), were newly isolated from Trichilia rubescens. The structures of the isolated compounds were determined through spectroscopic and spectrometric analyses, as well as ECD calculations. The natural occurrence of chlorinated limonoids 1–3 was confirmed by chemical methods and HPLC analysis of a roughly fractionated portion of the plant extract. Eight selected limonoid… Show more
“…Rubescins K 14 , L and M, from Trichilia rubescens , are the first examples of chlorinated limonoids. 13 The authors have shown that rubescins K, L and M are likely to be natural products rather than artefacts.…”
