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. [ABSTRACT FROM AUTHOR]
