Bombax ceiba Linn belongs to the family of Bombacaceae and is an important medicinal plant. In Bangladesh, Bombax ceiba Linn is locally known as “Shimul tree”. The whole part of the plant used as traditional folk medicine for the treatment of antidysentric, anti diahorreal and antipyretic effects. The present communication attempts to evaluate fatty acid analysis by GC-MS spectrophotometer, total protein content by Kjeldahl method and to quantify some active constituents i.e. alkaloid, saponin and flavonoid. The fatty acid compositions of the petroleum ether extract of leaves and seeds of Bombax ceiba grown in Bangaladesh were determined by gas chromatography- mass spectrophotometer. 8 compounds were identified from leaves and 13 compounds were identified from the seeds. For both cases Palmitic acid showed higher value. The findings from present study showed the protein content for seeds have higher value (18.89%) than leaves of Bombax ceiba . The present investigation showed that both leaves and seeds of Bombax ceiba contain phytochemicals such as flavanoids, alakaloids and saponins in appreciable quantities. The flavonoid content of leaves was 5.97% and for the case of seeds (5.72%), the alkaloid content for leaves was (9.73%) and for seeds (31.44), the saponin content for the case of leaves (13.90%) and for the case of seeds was(43.58%).

Confectionery Product

The aim of the paper was to obtain a new confectionery product, with added hemp protein powder, the protein content of the final product being determined. Hemp protein powder was added in order to improve oil quality, fatty acid profile (ω-3, ω-6 addition) and to increase the protein content. Protein content is not a current determination in the manufacturing process of traditional halva; in this paper the protein content of traditional sunflower halva and of the one improved with hemp protein powder was determined by Kjeldahl method. The determination allowed a better understanding regarding protein content of both types of halva.

Significant Difference

Abstract The technic of Winzler (1) for the determination of seromucoid has been studied to measure its reproducibility and the effect of certain environmental factors. Values obtained are fairly reproducible (a difference of 45 mg./l00 ml. BSAP between two specimens indicates a significant difference at the P = 0.05 level). Variables such as temperature, freezing and thawing, speed of addition of perchloric acid, and total protein content of serum have no practical influence on the final SM values. A modification in technic involving determinations on three different dilutions of a specimen gives differences greater than those found with the standard procedure for sera from patients with an inflammatory condition.

Two Parameters

Lupine seeds are promising soy replacement in food products and feeds. Eighteen cultivars of blue lupine seeds were examined to indicate the one most favourable in protein content and quality. Two parameters were studied, i.e. total protein content (with the Kjeldahl method) and amino acids composition (with the ultra performance liquid chromatography technique). Both parameters studied were variable and depended both on the cultivar and on the place of cultivation. Protein content was in the range of 28–41% and the worst cultivar, regardless of cultivation place, was cv. Kalif (average total protein content 29.37 ± 1.14%), while the best cultivar was Boruta (average total protein content 37.43 ± 0.98%). The blue lupine seeds were rich especially in leucine (5.3 ± 0.5–9.7 ± 0.5 g/16 g N), threonine (2.4 ± 0.7–4.9 ± 0.1 g/16 g N) and lysine (2.7 ± 0.4–5.6 ± 0.1 g/16 g N). The richest among all amino acids studied were the cv. Bojar seeds from Wiatrowo and cv. Oskar from Przebędowo. It was not possible to choose one cultivar preferable from the nutritional point of view, because a strong influence of cultivation place on protein content and quality was observed, especially as to the precipitation sum.

Kjeldahl Method

Nitrogen and protein contents in higher aquatic plants deriving from a natural habitat were determined. The following plants were examined: <i>Spirodela polyrrhiza</i> (L.) Schleid., <i>Elodea canadensis</i> Rich., <i>Riccia fluitans</i> L. Total nitrogen and nitrogen of respective fractions were determined by the Kjeldahl method. Nitrogen compounds were fractionated according to Thimann et al. Protein was extracted after Fletcher and Osborne and fractionated after Osborne. It was found, that total protein content in the plants under examination constitutes 18 to 25%o of dry matter. Albumins and glutelins are the most abundant protein fractions.
