P. Satyanarayana et al., CHARACTERIZATION OF A NEW SERIES OF DIPHYLLIN ESTERS FROM SAUROPUS-QUADRANGULARIS MUELL-ARG, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 34(6), 1995, pp. 571-572
Seven new diphyllin esters including nitrobenzoyl ester and two bromin
e containing compounds have been isolated from Sauropus quadrangularis
(Euphorbiaceae). Their structures determined have been on the basis o
f their H-1 NMR, (13) C NMR and mass spectral data and by chemical cor
relation with known compounds.
