Phenylpropanoids, Sesquiterpenoids And Flavonoids From Pimpinella Tragium Vill. Subsp Lithophila (Schischkin) Tutin

Abstract

A new sesquiterpenoid named germacradiene-6-O-(6'-O-acetyl)-beta-D-glucoside (1) and a new flavonol glycoside named rhamnetin-3-O-(2 ''-O-beta-D-glucopyranosyl)-beta-D-galactopyranoside (2), along with three known sesquiterpenoids dictamnol (3), radicol (4), germacradiene glucoside (5); three phenylpropanoids 4-methoxy-2-(3-methyloxiranyl)-phenyl 2-methylbutanoate (6), 4-methoxy-2-(3-methyloxiranyl)-phenyl angelate (7), thellungianin E (8); and a flavonol glycoside platanoside (9) were isolated from the aerial parts of Pimpinella tragium Vill. subsp. lithophila (Schischkin) Tutin. Their structures were elucidated by detailed analyses of 1D and 2D NMR, UV, IR and HR-ESI-MS data.
