Lipids and essential oil ofOriganum onites

Neutral lipids, glycolipids, phospholipids, pigments, and essential oil of the above-ground part ofOriganum onites L. (Lamiaceae) are isolated and characterized for the first time. The fatty-acid composition of the lipids and the components of the hydrocarbons, sterols, and essential oil are determined by GC/MS. Linolenic and palmitic acids dominate in the acids of the lipids. The main components of the hydrocarbons are nonacosane; of the sterols, \-sitosterol; of the pigments, chlorophylls a and b. A total of 54 components are identified in the essential oil.Presented at the IIIrd International Symposium on the Chemistry of Natural Compounds, Bukhara, Uzbekistan, 19–22 December, 1998.Translated from Khimiya Prirodnykh Soedinenii, No. 2, pp. 106–109, March–April, 2000.

Lipids and lipophilic components of Viburnum opulus fruits during maturation

The variation of the composition of neutral and polar lipids and lipophilic components during maturation of guelder rose (V. opulus L., fam. Caprifoliaceae) fruits was investigated. During fruit ripening, all lipid groups are accumulated, the highest accumulation rate being observed in the first period of maturation. In nonpolar lipids, this is due to a substantial increase in the content of triacylglycerides, whereas the contents of free fatty acids, methyl esters of fatty acids, monoacylglycerides, and especially esters of triterpenoid compounds decrease. During early maturation, all acyl-containing classes of lipids contain large amounts of saturated fatty acids (mainly, 16:0), whose content decreases during ripening, while the contents of unsaturated 18:1 and 18:2 acids increase.     

Lipids ofGlycyrrhiza glabra roots

Fourteen fatty acids were identified; the 18 2 fatty acid prevails among the unsaturated acids, and the 16 0 acid prevails among the saturated acids.Translated fromIzvestiya Akademii Nauk.
