Phytochemical examination%Sesquiterpene%Eremophilendiolide%Ligularia atroviolacea
From Ligularia atroviolacea, four new eremophilendiolides, 8β-hydroxy-eremophil-3,7 (1 1)-dien-12,8α(14,6α)-diolide (1),8β-methoxy-eremophil-3,7(11)-dien-12,8α(14,6α)-diolide (2), 8α-hydroxy-eremophil-3,7(11)-dien-12,8β(14,6α)-diolide (3) and eremophil-3,7(11),8-trien-12,8 (14,6α)-diolide (4), as well as a known diolide (5) were isolated. Their structures were elucidated on the basis of 1D and 2D NMR as well as ESI-MS spectral data.
