Lignoids in seedlings of Virola sebifera
MetadatosMostrar el registro completo del ítem
Quantitative analysis carried out by high performance liquid chromatography indicated the accumulation of a major secondary compound in seedlings of Virola sebifera which was isolated and identified as the lignan hydroxy-otobain. This lignan occurs only in trace amounts in the seeds, where cyclolignans (aryltetralones) are by far the major components. In addition to hydroxy-otobain, only hydroxy-aryltetralones were detected in the seedlings, indicating a selective process in the translocation of secondary compounds.
