	Title	Chemical Investigation of the Lichen Species Anaptychia fusca, Peltigera canina, and Omphalodiscus spodochrous
	Abstract	The three lichen species A n aptych ia fusca, P eltig era canina, and O m ph alodiscu s spodochrous have been studied with regard to their chemical content. Atranorin, gyrophoric acid, tenuiorin, allantoin, taurine, linoleic acid, a new sterol-C31H5202 , and waxes have been determined. The identity of the compounds was established by consideration of infrared, mass and nuclear magnetic resonance spectra. Besides, thin layer and column chromatographic techniques were used in this work.

	Title	Epicuticular Leaf Wax of Euphorbia helioscopia L. (Euphorbiaceae)
	Abstract	The epicuticular wax of Euphorbia helioscopia was fractionated into fatty acids, hydrocar bons, wax esters, aldehydes, methyl esters, triterpenol acetates, alcohols, sterols, and polar components. The com position o f the fractions was determined by GC, GC-MS, HPLC. Main com ponents within these lipid classes are hentriacontane, wax esters C ^ and C4g, octacosanal, hexacosanol and octacosanol, hexadecanoic acid, and ß-sitosterol. Lupeol and its acetate were also confirmed.
