Phenylpropanoids, Sesquiterpenoids and Flavonoids from Pimpinella tragium Vill . subsp. lithophila (Schischkin) Tutin

A new sesquiterpenoid named germacradiene-6 -O-(6'-O-acetyl)-β-D-glucoside (1) and a new flavonol glycoside named rhamnetin-3-O-(2′′-O- β-D-glucopyranosyl)- β-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.
