Natural Product Communications. 5(9):1421-1426. Interpretive Summary: Sage leaves were used traditionally as a tonic, stimulant, carminative, antiseptic, for inflammations in the mouth, and for infections. In our continuing phytochemical research in medicinal and aromatic plants, seven Salvia species and one interspecific hybrid received from the Dallas Arboretum and Botanical Garden were selected for study of their essential oil composition. Terpenoids were found as major compounds. In this study, the microdistillation technique provided an alternative technique to obtain essential oils from small amounts of plant materials.
Technical Abstract: Volatile compounds from seven Salvia species and one interspecific hybrid growing at the Dallas Arboretum and Botanical Garden, Texas, US, S. coccinea, S. farinacea, S. greggii, S. leucantha, S. longispicata × farinacea, S. madrensis, S. roemeriana and S. splendens were investigated for their chemical compositions using a microdistillation technique. Volatiles were analyzed by gas chromatography and gas chromatography-mass spectrometry (GC/MS). One hundred twenty seven compounds were identified representing 94.3-99.7% of the oils. The major component in each of the seven species was as follows: S. coccinea was (Z)-3-hexenal (31%), viridiflorol (19%); S. farinacea was 1-octen-3-ol (30%) and (Z)-3-hexenal (23%); S. greggii was 1,8-cineole (22%), borneol (17%), camphene (11%) and a-pinene (10%); S. leucantha was limonene (35%) and a-pinene (17%); S. longispicata × farinacea was 1-octen-3-ol (50%) and (Z)-3-hexenal (24%); S. madrensis was (Z)-3-hexenal (53%); S. roemeriana was limonene (49%) and a-pinene (20%) and S. splendens was (Z)-3-hexenal (36%), 2,5-dimethoxy-p-cymene (19%) and linalool (11%). The microdistillation method was fast, practical and a useful technique that enabled the isolation of the volatiles in samples with limited quantities were available.
