Jc. Chalchat et al., STUDY OF CLONES OF SALVIA-OFFICINALIS L. YIELDS AND CHEMICAL-COMPOSITION OF ESSENTIAL OIL, Flavour and fragrance journal, 13(1), 1998, pp. 68-70
The essential oil of Salvia officinalis L. in five selected clones of
different origins (France, Hungary, Portugal, Romania, Czech Republic)
was studied. Yields of oils from dried leaves were excellent (2-3%),
and higher than those previously reported. The alpha: beta-thujone rat
io varied according to origin. Overall, some of the oils were of high
quality in terms of their alpha- and beta-thujone and camphor contents
