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%).

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.

AbstractThe aim of our work was to develop a low-cost, portable device for the fast and easy determination of total protein content by using PDMS-based lab-in-a-syringe technology with removal of 3D-printed channels. We proposed two designs with a one-step PDMS curing and a two-step PDMS-curing fabrication procedure. The one-step PDMS microdevices were found to be the best in the view of preparation, repeatability, and stability of the reagent. This design was then applied for the determination of total protein content in biomedical products using the Bradford assay.
