Effects of Cyclopropenoid-Containing Cotton Oil on the Life Cycle and Lipid Metabolism of the Blowfly Lucilia sericata

Abstract: Purified oil of the Java Olive Bush, Sterculia foetida L. (Malvales: Sterculiaceae), fed to developing larvae resulted in deleterious effects on the life cycle of Lucilia sericata (Meigen). There was an inverse correlation between the concentration of oil fed to the larvae and the resulting pupal weight. Pupae obtained from oil-fed larvae were misshapen, and few adults emerged from pupae of larvae fed 0.5–3;1% oil. In addition, no eggs were obtained from these adults. Feeding S. foetida oil caused alterations in the fatty acid composition of the blowfly that resulted in changes in the ratio of saturated to unsaturated fatty acids in both the neutral lipids and phospholipids. Specifically the relative levels of the saturates — myristic, palmitic and stearic acids—increased, and their corresponding monounsaturates—myristoleic, palmitoleic and oleic acids—decreased, thereby altering the physical consistency of the fatty acid mixture. The same correlation existed between the level of oil fed and the effects both on life cycle and fatty acid composition; therefore it appears that the action of S. foetida oil on the fatty acid composition of the blowfly is responsible for the effects on its life cycle. In addition, it is likely that the cyclopropenoid group of sterculic acid is the active component, since supplements of oleic acid did not adversely affect L. sericata.

Chemical constituents from leaves of Sterculia foetida

Abstract: Objective To study the chemical constituents from the leaves of Sterculia foetida. Method Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectroscopic methods. Result Eight compounds were identified as 5,7,8-tetrahydroxy-4'-methoxyflavone-8-O-beta-D-glucoside (1), 5,7,8-tetrahydroxy-4'-methoxyflavone-7-O-beta-D-glucoside (2), quercetin-3-O-beta-D-glucoside (3), apigenin-6, 8-di-C-beta-D-glucoside (4), puerarin (5), 5,7,8,3'-tetrahydroxy-4'-methoxyflavone (6), 5,7,8-tetrahydroxy-3',4'-dimethoxyflavone (7), 5,7,8-tetrahydroxy-4'-methoxyflavone (8). Conclusion Compounds 1, 2 and 4-8 were isolated from this plant for the first time.

Synthesis, Surface Active Properties and Cytotoxicity of Sodium N-Acyl Prolines

Abstract: Sodium N-acyl prolines (NaNAPro) were synthesized using mixture of fatty acids obtained from coconut, palm, karanja, Sterculia foetida and high oleic sunflower oils via Schotten-Baumann reaction in 58-75% yields to study the synergetic effect of mixture of hydrophobic fatty acyl functionalities like saturation, unsaturation and cyclopropene fatty acids with different chain lengths and aliphatic hetero cyclic proline head group on their surface and cytotoxicity activities. The products were characterized by chromatographic and spectral techniques. The synthesized products were evaluated for their surface active properties such as surface tension, wetting power, foaming characteristics, emulsion stability, calcium tolerance, critical micelle concentration (CMC) and thermodynamic properties. The results revealed that all the products exhibited superior surface active properties like CMC, calcium tolerance and emulsion stability as compared to the standard surfactant, sodium lauryl sulphate (SLS). In addition, palm, Sterculia foetida and high oleic sunflower fatty N-acyl prolines exhibited promising cytotoxicity against different tumor cell lines.
