Most of the wastes emitted from the food processing industries are not utilized for any further purpose. The economic value of the food waste is very less when compared to the collection or reuse or discard. To increase the economic value we have to design the food waste as useful product or applicable in most of the current field. Nothing is waste in this world with this concept we have investigated the phytochemical analysis of drumstick peel (Moringa oleifera). The result supports the presence of phenols, alkaloids, flavanoids, glycosides and tannins. Since various functional groups containing molecules are present in the extract; it has been further subjected to antibacterial and hemolytic activities. To analysis the antibacterial studies we have employed human pathogenic Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) bacterium. The result of antibacterial activity clearly shows that it possesses significant activity on both bacterial cultures. The hemolytic activity was performed on red blood cells (RBCs). From this result we observed that drumstick peel extract has been considered as non-toxic on RBCs. Malachite green was selected to perform photocatalytic activity. The results stated that the drumstick peel extract possessed good behaviour towards photocatalytic investigation. The malachite green was degraded upto 99.7% using drumstick peel extract.

Phenolic compounds in drumstick peel for the evaluation of antibacterial, hemolytic and photocatalytic activities

Cocos nucifera is one of the most adaptable products which possess several protein fractions such as albumins, globulins, prolamines, glutelins 1 and 2 which were found and reported. Since C. nucifera was rich in nutritional value, it has wide medicinal applications. In this manuscript, we have reviewed on the anti-inflammatory, antioxidant, antimicrobial, antimalarial, leishmanicidal, and insecticidal activity. Also C. nucifera act as a low cost agricultural waste which was widely used in the preparation of nanoparticles: in this review, we have also focused on silver, gold, aluminum oxide, and doped nanoparticles like europium doped yttrium oxide nanoparticles. © 2015 Elsevier B.V.

Exploitation of Cocos nucifera a non-food toward the biological and nanobiotechnology field

Phyto-synthesis of transition metal nanoparticles is gaining importance due to their biocompatibility, low toxicity, green approach and environmental friendly nature. We used mesocarp layer extract of Cocos nucifera and was assessed for the synthesis of silver nanoparticles. The reduction of silver ions occurred when silver nitrate solution was treated with aqueous extract of C. nucifera coir at 60 °C. Synthesized silver nanoparticles (AgNPs) particles were confirmed by analysing the excitation of surface plasmon resonance (SPR) using UV-vis spectrophotometer at 433. nm. Further TEM analysis confirmed the range of particle size as 23 ± 2. nm. The XRD spectrum showed the characteristic Bragg peaks of 1. 1. 1, 2. 0. 0, 2. 2. 0 and 3. 1. 1 facets of the face centered cubic silver nanoparticles and confirms that these nanoparticles are crystalline in nature. Gas chromatography-mass spectrometry (GCMS) of coir extract confirms the presence of hydrocarbon such as nonacosane and heptacosane which may possibly influence the reduction process and stabilization of silver nanoparticles. This is the first account of C. nucifera coir assisted synthesis of biogenic Ag nanoparticles; the nanoparticles are notably smaller and better faceted compared with those synthesized by A. squamosa extracts previously reported. Synthesized Ag nanoparticles were effective anti-larvicidal agent's against Anopheles stephensi and C. quinquefasciatus. © 2012 Elsevier B.V.

Low-cost and eco-friendly phyto-synthesis of silver nanoparticles using Cocos nucifera coir extract and its larvicidal activity

New hydrazine derivatives were synthesized via reaction between 1, 3 cyclic diketones and hydrazinoisoquinoline derivatives. The reaction proceeded smoothly in ethanol under reflux temperature and furnished products in excellent yields (76-87%). The products have been purified and fully characterized by spectroscopy techniques. The compounds 8a-c showed good bacterial inhibition against Bacillus cerus and 8d-f showed good antifungal activity against Candida albicans.
