Secondary metabolites from Eryngium species

Abstract

From the seed and leaf extracts of Eryngium species, two new compounds were isolated, along with an aliphatic ketone and several known terpenoids reported from a member of Umbelliferae for the first time. Their structures were elucidated by chemical methods and spectroscopic analysis.

Keywords:

• Umbelliferae
• Eryngium
• sesquiterpenoids
• nor-sesquiterpene
• long-chain aliphatic ketones
