Lipids and lipophilic components from seeds of some fruit plants

Lipids and lipophilic components from seeds of grape seeds and apricot, almond, and peach pits were studied. The compositions of fatty acids and unsaponified oil compounds were established. Translated from Khimiya Prirodnykh Soedinenii, No. 3, pp. 269–271, May–June, 2009.     

Two New Withanolides from Physalis peruviana

Two new perulactone‐type withanolides, named perulactone C ( 1 ) and perulactone D ( 2 ), together with four known compounds, perulactone ( 3 ), perulactone B ( 4 ), blumenol A, and (+)‐(S)‐dehydrovomifoliol, were isolated from the aerial parts of Physalis peruviana. The structures of the new compounds were elucidated on the basis of 1D‐ and 2D‐NMR experiments, including HMBC, HSQC, ¹H,¹H‐COSY, and ROESY, as well as HR‐MS.     

Triacylglycerols of the seeds and fruit flesh ofMandragora turcomanica

The triacylglycerols (TAGs) of the seeds and fruit flesh ofManagora turcomanica have been investigated for the first time using the methods of mass spectrometry and enzymolysis. It has been found that in the TAGs of the seeds the 182 acids undergo specific esterification in the sn-2 position, while in the TAGs of the flesh this position is acylated by 181 and 182 acids. For both parts of the fruit the main TAG species is sn-1(3)-oleoyldilinoleate, and the main types are represented by triunsaturated and monounsaturated-diunsaturated glycerides.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent, fax (3712) 40 64 75.

Lipids of the seeds and flesh of the fruit ofMandragora turcomanica

The lipid compositions of the seeds and the flesh of the fruit ofMandragora turcomanica have been investigated. The qualitative identity of the lipid compositions of the two parts of the fruit has been shown and it has been found that the degrees of saturation of the fatty acids of the triacylglycerides and phospholipids and of the free fatty acids of the fruit flesh are higher than those of the lipid classes of the seeds.

Oil of the seeds of Hibiscus syriacus

Summary The physical and chemical properties and the fatty acid and triglyceride compositions of the oil ofHibiscus syriacus L. have been investigated. The oil was found to contain 16.87% of the cyclopropenoid acids malvalic and sterculic acids.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.
