Abstract

The composition of the volatile oils obtained from the leaves and flowers of Salvia przewalskii Maxim. grown in Tibet was analysed by gas chromatography-mass spectrometry (GC-MS) for the first time. Totals of 43 compounds were identified in the leaf oil and 69 compounds in the flower oil. A comparative study of the oil composition from the leaves and flowers found 22 common constituents of these oils, viz. α-thujene, β-phellandrene, linalool, terpinene-4-ol, diisopropenyl methyl vinyl cyclohexane, caryophyllene, germacrene D, borneol, caryophyllene oxide, spathulenol, germacrene B, δ-cadinene, humulene, farnesane, α-cadinol, β-caryophyllene, elemene, sabinene hydrate, γ-terpinene, p-cymene, camphene and α-pinene. The percentages of the most components were higher in the leaf oil than in the flower oil, especially those of β-phellandrene and caryophyllene (26.08% and 11.11%, respectively). Farnesene, chamigrene, n-hexadecane, epicedrol, cyclotetradecane, n-octadecane, 9-octadecen-1-ol, 1-heneicosyl formate, Z-8-hexadecen-1-ol acetate, n-heneicosane and n-pentacosane were the specific constituents found only in the flower oil, while β-cadinol was the specific constituent found only in the leaf oil.
