Aa. Mahmoud, 7-EPI-EUDESMANES, EUDESMANOIC ACIDS, EUDESMANOLIDES AND OTHER SESQUITERPENES FROM PLUCHEA-DIOSCORIDIS, Phytochemistry, 45(8), 1997, pp. 1633-1638
Re-examination of the chemical constituents of leaves of Pluchea diosc
oridis afforded, in addition to known compounds, seven new sesquiterpe
ne derivatives (two 7-epi-eudesmanes, two eudesmanoic acids, a eudesma
nolide, a guaiane and a xanthane epoxide). The structures were elucida
ted by spectroscopic methods. (C) 1997 Elsevier Science Ltd. All right
