Direct enantiomeric resolution of the germacrene-D derivative, (5E,7S*,9S*)-9-hydroxy-7-isopropyl-4,10-bis(methyIene)-5-cyclodecen-1-one, was carried out by HPLC with a chiral stationary phase. This method showed that germacrene-D contained in ylang ylang oil was 98% e.e., whereas germacrene-D extracted from Solidago altissima L. was almost racemic.
采用高效液相色谱法和手性固定相对胚芽烯-D 衍生物 (5E,7S*,9S*)-9-羟基-7-异丙基-4,10-双(甲基烯)-5-环癸烯-1-酮进行了直接对映体解析。该方法表明,依兰油中所含的胚芽烯-D 的等效度为 98%,而从 Solidago altissima L. 中提取的胚芽烯-D 几乎是外消旋的。
