TL;DR: The objective of this research was to obtain kepuh plants through direct in vitro regeneration throughHypocotyls and shoot tips explants were excised from sterile germinated seedlings and placed on shoot induction medium containing basal salts of Woody Plant Medium and various concentrations of plant growth regulators.
Abstract: Sterculia foetida Linn. is a large deciduous tree belonging to Sterculiaceae. Seed of S. foetida is used for treating skin diseases and rheumatism also can be used as a source of alternative bioenergy and medicine. The main problem of S. foetida cultivation is the limited supply of seed plants. Seeds development were very easy, but to produce fruit have to wait for approximately 5 years. The objective of this research was to obtain kepuh plants through direct in vitro regeneration. Hypocotyls and shoot tips explants were excised from sterile germinated seedlings and placed on shoot induction medium containing basal salts of Woody Plant Medium (WPM) and various concentrations of plant growth regulators. The results showed that the best medium of shoots elongation were WPM + 1 mgL-1 kinetin + 5 mgL-1 GA3. Highest percentage of roots (65%) occurred on WPM with 5 mgL-1 IBA which average number of roots was 3.1. Rooted plantlets were acclimatized to field conditions by placing them in pots containing sterilized and compost medium (1:1) and subsequently transferred to filed with 80% survival.

TL;DR: In this paper, transesterified new biodiesel of sterculia foetida oil is mixed with diesel and the engine performance, combustion and emission was analysed, the primary objective work is to produce a new alternate and biodegradable fuel for compression ignition engine.
Abstract: In the present work, transesterified new biodiesel of sterculia foetida oil is mixed with diesel and the engine performance, combustion and emission was analysed The primary objective work is to produce a new alternate and biodegradable fuel for compression ignition engine The biofuel oil is an extract from sterculia foetida seed and transesterfied with 20 % methanol and 2 % KOH The transesterfied biofuel concentrations were varied at 25%, 50%, 75% and 100% with diesel viz B25, B50, B75 and B100 The engine is operated at different load conditions with different concentration of fuel The experiments are conducted and the fuel blend B25 produces maximum of brake thermal efficiency in comparison with other biodiesel blends and produced maximum heat release and minimum emission produced at B25 biodiesel blend

TL;DR: The influence of Sterculia foetida oil on sexual maturity was determined as indicated by the age of the rat at the time the vagina opened and the length of the estrous cycles.
Abstract: Edward T. Sheehan. EFFECTS OF DIGESTION OF STERCULIA FOET3DA OIL ON THE SEXUAL DEVELOPMENT OF THE FEMALE RAT. M. S. Thesis, Committee on Agricultural Biochemistry and Nutrition. The University of Arizona, 1964. Previous workers have shown that Sterculia foetida oil is a rich source of the Balphen-active cyclopropenoid fatty acid, stercullc. This fatty acid produces several abnormal biological effects in the avian species, one of which is delay of the sexual development of pullets. In this thesis the effect of this oil on the sexual development of the female rat is reported. Groups of 10 weanling female Sprague-Dawley albino rats were fed purified diets with 4$ corn oil or k'fo safflower oil control diets, or control diets substituted with 2$ Or 3$ Sterculia foetida oil to determine the influence of Sterculia foetida oil on sexual maturity as indicated by the age of the rat at the time the vagina opened and the length of the estrous cycles. In addition, the effects of Sterculia foetida oil on growth and weights of certain organs were noted. Feeding of 2% safflower oil-2% Sterculia foetida oil diet delayed sexual maturity as shown by delayed opening of the vagina

TL;DR: In this article, the seeds of Sterculia foetida were dehulled, defatted, and ground to 60 BS mesh size flour, which contained 40% protein as compared to 15% in the whole seed meal.
Abstract: The seeds of Sterculia foetida were dehulled, defatted, and ground to 60 BS mesh size flour. The dehulled-defatted
seed flour (DDSF) contained 40% protein as compared to 15% in the whole seed meal. The effects of flour to solvent
ratio for extraction, extraction time, protein precipitability at different pH and addition of salt on protein solubility were
assessed. The buffer capacity of the DDSF in acidic and alkaline pH ranges was assessed. Water absorption and fat
absorption capacities for the whole seed meal were 170 and 60%, whereas the corresponding values for the DDSF were
79 and 120%, respectively. Significant increase in foam capacity and foam stability were observed in the DDSF, but not
in whole seed meal.

TL;DR: In the ultracentrifuge the proteins from the Sterculia foetida nut, showed one major and a number of minor components, which were separated from the minor components by fractional precipitation methods.
Abstract: In the ultracentrifuge the proteins from the Sterculia foetida nut, showed one major and a number of minor components. The major component was separated from the minor components by fractional precipitation methods. Using sedimentation and diffusion measurements, a molecular weight of 362, 000 and frictional ratio of 1.38 were found for the major component.
