Gracilin a new sesquiterpene lactone from artemisia gracilescens


, : Gracilin a new sesquiterpene lactone from artemisia gracilescens. Khimiya Prirodnykh Soedinenii (3): 339-343

Acetone extraction and column chromatography of resin were used to isolate gracilin from the aboveground part of A. gracilescens. The structure of 1-keto-6.beta.,7.alpha.,11.beta.-(H)-eudesm-4(5)-en-6,12-olide was established for the compound by IR and PMR spectra.

In sepsis, plasma ceruloplasmin (Cp, mg/L) is known to increase as part of the acute phase response. However, there is poor knowledge of the patterns of increase and correlation with changes in other biochemical variables, and our stud...
