The bio-plastics that are produced either from fossil material or can be synthesized from biomass or renewable resources, such as Poly-lactic acid (PLA), Polyethylene glycol (PEG) and Poly – ε – caprolactone (PCL) are been reported as a material of choice for biomedical applications due to their good physical properties such as crystallinity, storage modulus, glass transition temperature and bioresorbable property. These biodegradable polymers have wide applications in tissue engineering, wound management, drug delivery, orthopedic devices, manufacturing of fibrous and porous scaffolds. Co-polymerizing these biodegradable monomers in varying proportions with other polymer has extended stiffens and physico-chemical properties. Depending on the origin of their materials, bio-plastics are different in their monomer composition and physical property, which make them interesting from medical point of view. This review thus highlights the synthesis and blending of bio-plastics along with their degradation process when used as in biomedical devices. These biodegradable plastics have hydrolysable linkages in the backbones such as esters, orthoester, anhydride, carbonate, amide, urea and urethane that make them biocompatible to...

Lantana camara Linn. is considered as a notorious weed and a popular ornamental plant. It is noted from ancient time that plants have been an excellent source of medicine. Since very long time Lantana camara has been reported as one of the most important medicinal plants in the world. Lantana camara is used in traditional medicine system for the treatment of cuts, swellings, ulcers, cataract, bilious fever, itches, eczema, and rheumatism. Various parts of Lantana camara plant are used in the treatment of cold, headache, whooping cough, asthma, chicken pox, bronchitis, eye injuries, and arterial hypertension. L. camara has scientifically studied for various therapeutic activities like antibacterial, antioxidant, antipyretic, insecticidal, antimicrobial, wound healing, etc. Nowadays this plant Lantana camara is worked in several recent advanced techniques like phyto-extraction of heavy metals, phytoremediation of particulate pollution and many others. Various literature has reported the phytoconstituents present in all parts of Lantana camara. In last few decades, scientist and researchers throughout the globe have elaborately examined the chemical composition of the...

Okra is a cultigen (a plant that has been altered by humans through a process of selective breeding). The exact origin of okra is unknown, but it is thought to have come from Africa, where it has been grown as a crop for centuries. Evidence suggests it was grown in Egypt as long ago as 2,000 BC. Today it is widely cultivated for its edible green fruits, which are harvested when immature (after 3 – 5 days of development), and are infamous for their slimy mucilage. It plays a vital role to preserve our health. In recent times, the use of herbal products has increased tremendously in the western world as well as developed countries. India is one of the most medico-culturally diverse countries in the world where the medicinal plant sector is part of a time-honoured tradition that is respected even today. Medicinal plants are believed to be safer and proved elixir in the treatment of various ailments. Abelmoschus esculentus (Okra) is an important medicinal plant of tropical...

Antimicrobial peptides (AMPs) are the crucial factors, which plays an important role in host defense mechanisms. AMPs are ubiquitous and found in diverse organisms ranging from microorganisms to animals. Plants are the precious source of natural antimicrobial molecules including antimicrobial peptides known as plant antimicrobial peptides (PAMPs). PAMPs can be divided into different families based on their, molecular weight, activity against different microbes, structure, charge of molecules, content of disulphide bond and mechanism of action. Based on number of cysteine residues and disulfide bonds, PAMPs are categorized into six main families. These peptides may lead to degradation of nutrients that are specific or essential for microbes to grow, interfering with microbial membrane or by conflicting with their metabolism. PAMPs exert multiple antimicrobial activities which includes membrane permeabillization, interference with DNA, RNA and protein synthesis that might provide a suitable approach to prevent bacteria from developing resistance. This review provides an overview of all the major plant AMP families including their structure, function, mechanism of action and antimicrobial...
