A New Phenolic Glycoside from Kalimeris shimadae

Fifteen phenolic constituents were isolated from the 80% ethanol extract of Kalimeris shimadae , including two phenolic glycosides ( 1 , 2 ), six flavonoids ( 3–8 ), five phenylpropanoids ( 9–13 ), and two lignans ( 14 , 15 ). Their structures were identified by spectroscopic analysis and comparison with literature data. Compound 1 was a new glucosyringic acid derivative, whereas compounds 2–14 were first discovered from K. shimadae .
