ABSTRACT
Fractionation of the antimicrobial petr. extract of Salvia lanigera Poir. roots, afforded two more diterpene quinones deoxyneocryptotanshinone I and 7-oxoroyleanone II. Their structures were elucidated using 400 MHz 1H-NMR and other spectroscopic evidences

Terpenes/isolation & purification , Plant ExtractsABSTRACT
The polar fraction of the roots of Phagnalon barbeyanum Aschers and Schweinf. Afforded the new benzofuran glucoside 1, 5-acetyl, 3-hydroxy-2 [1'-hydroxyallyl][2']]-2, 3-dihydrobenzofuran-1'-O-beta-D- glucopyranoside. The structure was elucidated by high field spectroscopy and other chemical evidence

The increasing number of structurally interesting and biologically active diterpene quinones that have been discovered and still to be isolated from many members of the genus salvia calls for an update review. This article desribes the recent advances in their structural variation and distribution pattern in the different studied species
