Separation of Trimethylsilyl Ethers of Triterpenes by Thin Layer Chromatography: Triterpenes in Wood from Populus tremula L..

Abstract

The following alcohols have been isolated from Populus tremula wood: [alpha]- and[beta]-amyrine cycloartenol, [beta]-methylene-cycloartanol, lupeol, butyrospermol, 4[alpha]methyl-[DELTA] 7,24(28)-stigmasta-dienol-(3[beta]) ("[alpha]-sitosterol"), and)[beta]-sitosterol. The separation of the various compounds was achieved by argentative thin layer chromatography of the respective trimethylsilyl ethers. The mass spectra of the 4,4-dimethyl-9,10-cyclosterols are described.
