A new eudesmanolide 13-hydroxy-4 alpha H-eudesman-5,7(11)-dien-12,8 beta-olide (1) and a new aromatic derivative 3-methyl-8-acetoxy-9,10-diisobutanoyloxy-p-cymene (6), along with ten known compounds were isolated from the roots of Carpesium cernuum L. Their structures were elucidated by spectral
Two new sesquiterpene lactone glycosides and two new eudesmanolides, along with twelve known compounds were isolated from seeds of Carpesium macrocephalum. The structures of these new compounds were elucidated as 2alpha- O-beta- D-glucopyranosyl-5alpha, 11alpha H-eudesma-4(15)-en-12,8beta-olide (
The genus Carpesium plants contain many kinds of sesquiterpenes. Up to now, more than 201 sesquiterpene compounds have been isolated and identified, including 86 germacranolides, 30 eudesmanolides, 29 guaianolides, 23 sesquiterpene dimers, 9 pseudoguaianes, 9 carabranolides, 7 xanthanolides, 6
BACKGROUND
The plants in the genus Carpesium, which grow naturally in Asia and Europe, have long been used in traditional Chinese, Korean and Japanese medicines. The antipyretic, antimalarial, haemostatic, anti-inflammatory and detoxifying properties of their extracts enabled their use in the
