TL;DR: The NaNAIle exhibited promising cytotoxicity against human cancer cell lines except 3 and 5 and showed antimicrobial activity against Gram-positive and Gram-negative bacteria and exhibited good antioxidant properties.
Abstract: Mixture of fatty acids obtained from coconut, palm kernel, palm, jatropha, karanja, Sterculia foetida, and high oleic sunflower oils were used for the preparation of sodium N-acyl isoleucines (NaNAIle) via Schotten–Baumann reaction except castor oil which was prepared in thermal condensation in good yields. The products were characterized by chromatographic and spectral techniques. Surface active properties such as surface tension, wetting, foaming characteristics, emulsion stability, calcium tolerance, and micellization properties were evaluated for all the synthesized products. The results showed that all the products exhibited superior surface active properties like critical micelle concentration (CMC) and emulsion stability when compared to the commercial surfactant, sodium lauryl sulphate (SLS). The NaNAIle also exhibited promising cytotoxicity against human cancer cell lines except 3 and 5. 5, 6, and 8 showed antimicrobial activity against Gram-positive and Gram-negative bacteria. 1, 2, 7, and 8 exhibited good antioxidant properties.

TL;DR: The roasting process modified some physicochemical properties and the fatty acid composition of the seed oil, particularly by decreasing its content of sterculic acid, to be the first report on the fatty acids composition of S. apetala seed oil.
Abstract: In the tropical rain forests of southeastern Mexico, the use of Sterculia mexicana and Sterculia apetala seed oils for human and animal nutrition is common. However, the seeds contain cyclopropene fatty acids, whose consumption is related with beneficial as well as detrimental physiological effects. The aim of this study was to determine the fatty acid profile and the physicochemical characteristics of S. apetala seed oil and to evaluate the effect of roasting on both aspects. Cyclopropenoic fatty acids, sterculic acid and malvalic acid were identified in the natural and roasted seed oils. The major component in the seed oil was sterculic acid, as has been reported for Sterculia mexicana and Sterculia foetida. The roasting process modified some physicochemical properties and the fatty acid composition of the seed oil, particularly by decreasing its content of sterculic acid. To our knowledge, this is the first report on the fatty acid composition of S. apetala seed oil.

Materials & Methods: The purpose of this study is to explore the anticonvulsant activity of ethanolic extract of Sterculia Foetida using Pentylenetetrazole and maximal electric shock induced convulsions in rats. MES Model: rats were divided into 4 groups of 6 rats each. GROUP-I (NC) received 2% GA 2ml, GROUPII (STD) received Phenytoin 25mg/kg, GROUP-III, IV received low dose (250 mg/kg) & high dose (500 mg/kg) of Sterculia Foetida respectively orally Convulsions were produced in all groups by giving maximal electric shock of 150 mA for 0.2sec after 1 hour of giving test and standard drugs orally. Tonic clonic seizures were produced after giving electric shock. Recovery time was noted. The percentage of inhibition of convulsions by drugs was measured and compared between the control, standard and test. PTZ model: Rats were divided and test drugs were given same as above model but standard drug was Sodium valproate (50mg/Kg). Convulsions were induced by giving the Pentylenetetrazole IP 1 hr after giving test and standard drugs intraperitonially (IP). The onset of convulsions, duration of action, and type of seizures were noted and compared between standard and test groups. Results: In MES Model, ethanolic extract of Sterculia Foetida significantly (p<0.001) decreased the duration of tonic clonic seizures and recovery time. The percentage of inhibition was 66%. In PTZ Model the onset of seizures was delayed (p<0.002) with low and

TL;DR: The cytotoxic evaluation of the imidazolines against different cancer cell lines showed excellent cytotoxicity for dodecyl, tetradecyl, octadecyl and coconut-based imidrazolines, which exhibited good anti-cancer activity towards HeLa, A549 and MCF-7 cell lines.
Abstract: A series of eight fatty imidazolines were synthesized under microwave-assisted conditions using different fatty acids namely octyl, decyl, dodecyl, tetradecyl and octadecyl, mixed fatty acids prepared from Sterculia foetida (containing cyclopropene-rich fatty acids), coconut (containing medium-chain-rich fatty acids), palm (containing saturated-rich fatty acids) and sunflower (containing unsaturated-rich fatty acids). Coconut, sunflower and non-edible oil S. foetida-based imidazolines were synthesized for the first time. The fatty imidazolines were evaluated for anti-fungal activity and found to be good to excellent (MIC, 4.68–18.75 μg ml−1) against the tested Candida strains as compared with fluconazole (MIC, 16–64 μg ml−1) as standard. The fatty imidazolines also exhibited excellent to moderate anti-bacterial activity (MIC, 4.68–75 μg ml−1) against Staphylococcus aureus MTCC 96, S. aureus MLS 16 MTCC 2940 and Pseudomonas aeruginosa MTCC 2453 as compared with neomycin (MIC, 18.75 μg ml−1) as standard. The cytotoxic evaluation of the imidazolines against different cancer cell lines such as HeLa (Human Cervical Cancer Cell line), A549 (Human Alveolar Adenocarcinoma Cell line), MDA-MB-231& MCF7 (Human Breast Adenocarcinoma Cell line) and Neuro2a (Mouse neuroblastoma cell line) showed excellent cytotoxicity for dodecyl (3b), tetradecyl (3c), octadecyl (3d) and coconut (3f)-based imidazolines. Sunflower-based imidazoline (3g) exhibited good anti-cancer activity towards A549, Neuro2a and palm-based imidazoline (3h) towards HeLa, A549 and MCF-7 cell lines.

TL;DR: In this article, the authors described an investigation of using oil extracted from Bastard Poom beans as a biofuel and found that to obtain a liter of oil, approximately 4.29 kg of beans are needed (oil extraction ratio of 21.57 % by weight).
Abstract: The paper describes an investigation of using oil extracted from Bastard Poom beans as a biofuel. Unlike Palm oil, Bastard Poom bean oil is non-edible, therefore using it as a fuel does not create a demand conflict between food and fuel. Bastard Poom are a type of softwood trees and grown quickly. We find that to obtain a liter of oil, approximately 4.29 kg of beans are needed (oil extraction ratio of 21.57 % by weight). The chemical compositions of oil are determined. The oil consists of 40.16 %. Palmitic acid, 15.67 % Cis-11,14-Eicosadienoic acid and approximately 15 % each of Cis-9-Oleic and Cis-9,12-Linoleic acids. The oil heating value is 39,638 kJ/kg. The viscosity tested at 40 °C and densities tested at 15 °C are 44.61 mm2/s and 929.6 kg/m3, respectively. As a result, it has a considerable potential as an alternative to other biofuels among communities and farmers.
