Minor Methylated Pyranoamentoflavones from Calophyllum venulosum
Abstract Two new biflavonoids, pyranoamentoflavone 7-methyl ether (1) and pyranoamentoflavone 4′-methyl ether (2), have been isolated from the leaves of Calophyllum venulosum. The structures of these two new compounds were elucidated by spectroscopic data.
