Western Australian Sandalwood Oil—New Constituents of Santalum spicatum (R. Br.) A. DC. (Santalaceae)

Abstract Commercial Australian sandalwood oil produced from Santalum spicatum (R. Br.) A. DC. roots was analyzed using GC and GC/MS. Seventy constituents were identified: four monoterpenes, 64 sesquiterpenes and two others. Four compounds (Z)-β-curcumen-12-ol, (Z)-12-hydroxysesquicineole,6,10-epoxybisabol-2-en-12-olandnor-helifolen-12-al were found to our knowledge for die first time in nature and were characterized using 1H-, 13C-N M R, GC/FTIR and GC/MS analyses.

New Caledonian Sandalwood Oil—a Substitute for East Indian Sandalwood Oil?

Abstract Three qualities of New Caledonian sandalwood oil were analyzed using GC and GC/MS. Eighty-four constituents were identified: 10 monoterpenes, 72 sesquiterpenes and two others. In addition β-bisabolol/epi-β-bisabolol isomers were isolated and characterized via chiral GC chromatography. Our results indicate that New Caledonian sandalwood oil is much closer related to East Indian sandalwood oil than its Western Australian counterpart.

Isolation and Chiral GC Analysis of β-Bisabolols—Trace Constituents from the Essential Oil of Santalum album L. (Santalaceae)

Abstract The essential oil produced from the heartwood of Santalum album L. was analyzed using GC/MS. Forty-four constituents were identified: one monoterpene and 43 sesquiterpenes. 2,10-Bisaboladien-6-ol (= β-bisabolol/epi-β-bisabolol) was one of the trace compounds found in east Indian sandalwood oil. Chiral GC analysis showed that besides the main stereoisomer, which possessed an (R,R)-configuration, all three other isomers were also present.

Isolation of Anisyl Acetone from Agarwood Oil

Abstract The essential oil of Aquilaria agallocha Roxb. was analyzed using GC/MS. The main constituents were found to be agarospirol (12.1%) and jinkoh-eremol (10.0%). Anisyl acetone was isolated as a minor constituent and fully characterized from a commercial sample of agarwood oil.

Two New Bisabolene Diols from the Stem Wood Essential Oil of Vanillosmopsis erythropappa Schultz-Bip. (Asteraceae)

Abstract The stem wood oil of Vanillosmopsis erythropappa Schultz-Bip. was analyzed using GC/MS. Forty-three constituents were identified: 31 sesquiterpenoids, one phenylpropane and 11 others. 2-Bisabolene-7, 11-diol and 10-bisabolene-3,7-diol were found for the first time in nature and were characterized using 1H-, 13C-NMR, GC/FTIR and GC/MS analyses.

Santalum spicatum (R. Br.) A. DC. (Santalaceae)—nor-Helifolenal and Acorenol Isomers: Isolation and Biogenetic Considerations

Abstract Six stereoisomers of nor-helifolen-12-al and four isomers of acoren-11-ol (α-acorenol, epi-α-acorenol, β-acorenol, epi-β-acorenol) were identified for the first time in Australian sandalwood oil.
