Abstract Three new sulphate ester saltsderivedfrom known coumarin alcohols–one of them tertiary–have been obtained from roots of Seseli libanotis subsp. eu-libanotis . Their structures were established as (2′ S )-rutaretin-1″-sulphate, (3′ R )-lomatin-3′-sulphate and (3′ R ,4′ R )-khellactone-3′-sulphate. They were together with their parent alcohols characterized by 13 C NMR spectroscopy. It is
摘要 从 Seseli libanotis subsp. 的根中获得了三种源自已知香豆素醇的新硫酸酯盐 - 其中一种是叔醇。eu-libanotis . 它们的结构被确定为 (2' S )-rutaretin-1"-sulphate, (3' R )-lomatin-3'-sulphate 和 (3' R ,4' R )-khellactone-3'-sulphate。它们与通过 13 C NMR 光谱表征的母体醇一起。这是关于植物中香豆素硫酸盐的第一份报告。
