New Coumarins from the Family Apiaceae. III. Lomatin and Phlojodicarpin Glycosides from Phlojodicarpus sibiricus
摘要
Two new coumarins 1 and 2 and known compounds 3–12 were isolated from the herb of Phlojodicarpus sibiricus (Fisch.) Koso-Pol. (Apiaceae) growing in Mongolia. The new compounds were identified as (+)-(3′S)-lomatin 3′-O-(6′′-O-β-D-apiofuranosyl)-β-D-glucopyranoside (phlojosibiriside VIII, 1) and (1′S,2′S)-phlojodicarpin 1′-O-β-D-glucopyranoside (phlojosibiriside IX, 2) using UV and NMR spectroscopic and mass spectrometric data.
