Two recent reports from another laboratory on hinokiflavone and robustaflavone in S. selaginoides, and hinokiflavone, isocryptom erin, cryptomerin B and amentoflavone 7-methylether in S. denticulata are shown to be based on 1H -NMR data that are inconsistent with the biflavone structures proposed. In the current paper a comparison of the 1H -nmr spectra is made both with published data and with new data derived from authentic samples. It is concluded that in both reports, only for am entoflavone the NMR data provide convincing supportive evidence. These reports are considered therefore to merely confirm an earlier identification of am entoflavone in these species
