Chemosterilant Activity of Oils, Especially Oil of Sterculia foetida, in the House Fly

Abstract: Oils containing cyclopropene acids and epoxy groups were tested as chemosterilants of the adult house fly, Musca domestica L. The most effective oil, derived from seeds of Sterculia foetida L., sterilized only the female. Flies fed diets containing 2.5 and 5% of this oil produced no eggs, even though both sexes were present throughout the test period. Oil from S. foetida nuts aged 10 months retained its activity, an indication that the active principle is quite stable prior to extraction. The oil is reported to be edible. Therefore, it may be possible to use it in areas where aziridine sterilants cannot be used. This female sterilant may also buttress the action of the more effective sterilants that are active against both sexes.

Phytochemical screening of Sterculia foetida seed extract for anti-oxidant, anti-microbial activity, and detection of apoptosis through reactive oxygen species (ROS) generation, mitochondrial membrane potential (MMP) decrease, and nuclear fragmentation in human osteosarcoma cells

Abstract: Sterculia foetida seeds are rich in various secondary metabolites such as fatty acids, alkaloids, flavonoids, and saponins, and possess multidisciplinary anti-inflammatory, anti-microbial, anti-dia...

Green synthesis of silver nanoparticles using water soluble gum of Sterculia foetida and evaluation of its antimicrobial activity

Abstract: In the present study, green synthesis of Ag0 nanoparticles using gum extract as reducing and capping agent was investigated. Sterculia foetida gum extract prepared at different concentrations (0.1% to 0.01%) was used for the biosynthesis of silver nanoparticles. The gum extract incubated with 1mM AgNO3 and autoclaved for 15 mints showed gradual change in the colour from yellow to reddish brown indicating the formation of silver nanoparticles. Different spectral analyses were used for confirming nanoparticle formation. Sterile silver nanoparticles devoid of bacteria, viruses, and spores could be produced using this method. Antibacterial activity of the prepared nanoparticles was investigated and the synthesized nanoparticles showed inhibitory activity on Gram-positive and Gram-negative bacteria.

Structure of Malvalic Acid and Some Related C 18 and C 19 Cyclo propane Fatty Acids

Abstract: IN recent years an interesting group of fatty acids containing a cyclopropane or a cyclopropene ring has been isolated from natural products or synthesized. This work followed the discovery by Hofmann et al. 1,2 of a biologically active C19H36O2 cyclopropane fatty acid, lactobacillic acid, in the lipides of Lactobacillus arabinosus and L. casei. Four more C19 acids of this type were synthesized3,4—the DL, cis and trans, 9-10 and 11-12, methylene octadecanoic acids. The crystal structures of two of these racemates have been studied5,6, namely, the DL trans 9-10 and DL cis 11-12, and shown to have the characteristic straight- and bent-chain configurations illustrated in the electron density Fourier projections in Figs. 1 and 2. From the similarity in the diffraction data, the other two racemates are believed to be structurally isomorphous7 in the trans and cis series, respectively. Of these, the DL cis 9-10 acid was shown7 to be identical with the dihydrosterculic acid obtained4 by hydrogenation of the sterculic acid8, C19H34O2, from the kernel oil of the tropical tree Sterculia foetida.

Optimization and Performance parameters for adsorption of Cr6+ by microwave assisted carbon from Sterculia foetida shells

Abstract: Modeling of adsorption of Cr6+ on to activated carbon prepared from Sterculia foetida dried seed shells under different drying techniques namely sun, oven, and microwave drying (450W, 600W, 900W power). Optimization of process parameters such as pH, adsorbent dosage (g/ml), temperature (°C), contact time (min) were evaluated using Central Composite Rotatable Design (CCRD) of Response Surface Methodology (RSM). For batch adsorption studies at pH 3, adsorbent dosage of 1.5 g/ml, temperature 35°C and contact time 90 min were found to be optimum for the system under consideration and Microwave Activated Carbonized Sterculia foetida (MACSF) at 450W was found to be best suited for the adsorption of Cr+6 ions. The system was found to follow Langmuir type monolayer adsorption for the given operational parameters. SEM analysis was used to study the surface morphology of the carbon samples and the effect of pretreatment on carbonization.
