Weitere Triterpene aus Melissa officinalis L.

Abstract: Melissa off. L. enthalt als weitere Triterpene: Pomolsaure, drei 2-Hydroxy-und eine 20-Hydroxytiterpensaure. In der Wurzel kommen Betulindure, Betulin und drei 2-Hydroxytriterpen-sSuren vor. Die Konfiguration der 2,3-Dihydroxytriterpensiuren wird durch Synthese der vier isomeren 2-Hydroxydcrivatc von Olcanolsiure, Ursolsiure und @Arnyrin bewiesen.Further Triterpenes from Melissa officinalis L.Melissa off. contains as further triterpenes pomolic acid, three 2-hydroxy-and one 29-hydroxytriterpenic acid. The root… Show more

“…These biological activities have been attributed to the essential oil, , flavonoids , and phenolic acids ,, such as rosmarinic and caffeic acids. Studies on the essential oil have been extensive, but information of the nonvolatile components is scarce. ,, Thus, we now describe the isolation and characterization of five new disulfated ursene or oleanene triterpenes and a new ursene glycoside from a polar extract of the stems and leaves. Their structures were elucidated by extensive spectroscopic methods including 1D ( 1 H and 13 C) and 2D NMR (DQF-COSY, HSQC, and HMBC) experiments as well as HRESIMS analysis.…”
