Abstract
Prawns are a common food for humans all around the World. Particularly the prawn exists naturally in south East Asia. Prawn shells contain ash, fibre, minerals and proteins. Prawns like a Shrimps. It’s a Dendrobranchiata family. Prawn shells were collected from Chindaripet market. Deproteinization followed by demineratisation was carried out to obtain the final product chitin. Cassia auriculata is a legume tree in the subfamily Caesalpinioideae. It contains antioxidants, cardiac Glycosides, anthraguinones, tannins, carbohydrates, alkaloids, phenols, saponin and flavonoids. Cassia auriculata flower has anti- bacterial, anti- diabetic property, the flower taste is stringent, pungent and bitter. Cassia auriculata flowers were dried under room temperature for 2 to 3weeks flowers and grounded with mechanical blender. Then chitin and silver nanoparticles were prepared along with Cassia auriculata flower extract which was extracted with both ethanol and water. Scanning Electron Microscope (SEM) was done by chitin nanoparticles to identify the particle size and morphology. Fourier Transform Infrared Spectroscopy (FTIR) was done to identify the active compounds. Chitin nanoparticles were used widely in various applications that evaluates anti-microbial activity using E. coli, Staphylococcusaureus, Salmonella typhi, Klebsiella pneumoniae, Staphylococcus mutans, Entero coccus spp, then anti-inflammatory activity gives better inhibition, anti-larvae activity using mosquito larvae. Cassia auriculata (fresh, ethanol) nanoparticles killed all larvae, anti-coagulant and thrombolytic activity were observed.
Highlights
Prawns are similar to shrimp but it’s different in the gill structure
Cassia auriculata is commonly called Matura tea tree, Ranawara, Avaram which is grown in black soils on stony hillsand along the road side [2,3,4,5]
Prawn shells were treated with sodium hydroxide and hydrochloric acid to prepare chitin. 0.05g of silver nitrate and 0.25% of glucose were added to 10 ml of distilled water
Summary
Prawns are similar to shrimp but it’s different in the gill structure. Prawn shells contain chitin (C8H13O5N)n which is a long chain polymer [1, 11]. Cassia auriculata is commonly called Matura tea tree, Ranawara, Avaram which is grown in black soils on stony hillsand along the road side [2,3,4,5]. The taste of Cassia auriculata flower is bitter, astringent, and pungent [7,8,9,10]. Cassia auriculata contains anti-oxidants and cardiac glycosides. This plant, flower powder were traditionally used in the treatment of diabetics. It’s used for urinary problems, kidney disorders and skin problem [1216]
