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.

Lipid components of the seeds ofViburnum opulus (Caprifoliaceae family) were investigated. The neutral lipids consist of eight classes, the glycolipids consist of three classes, and the phospholipids contain seven classes. The fatty-acid contents of all of the acyl-containing lipids were determined. The 18∶2 fatty acid is the main component of all the lipid fractions. The content of saturated acids is greater in the glycolipids and phospholipids. The lipophilic components, higher fatty alcohols and sterols, were identified.

A petroleum ether extract ofGlycyrrhiza glabra L. roots was investigated. The extract contains 70% neutral lipids and 30% polar lipids. Hydrocarbons, sterols esters, triacylglycerols, free fatty acids, free sterols, and diacylglycerols were identified. The fatty acid contents of all of the acyl-containing lipids were determined. 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.

A new alkaloid, ternatine (C24H33NO5), was isolated from aerial parts of theDelphinium ternatum plant. According to the1H,13C NMR, IR, and mass spectra of the base and its triacetate, ternative was assumed to have the structure of 4β-methyl-7α-isobutyryloxy-11α,15β,19β-trihydroxyhetisane.
