Summary
From the roots ofPilopleura kozo-poljanskii Schischk. a new chromone has been isolated which has been called pilopleurin. On the basis of the results of hydrolysis and UV, IR, and NMR spectroscopy, it has been established that pilopleurin has the structure 5-hydroxy-2,2′,2′-trimethyl-3′-senecioyloxy-3′,4′-dihydropyrano-5′,6′:6,7-chromone.
