Dried rhizomes (1000 gm) of Zingiber officinale Rosc. was subjected to soxhlet extraction to obtain 200 gm of thick paste. It is mixed with silica gel to make fine powder of 230 gm. This fine powder is subjected to column chromatography. All fractions of n-hexane and ethyl acetate in the ratio of 6:4 and 5:5 showed the same Rf value (0.93) on thin layer chromatography (TLC), so they are mixed and evaporated to collect 6-gingerol. High performance liquid chromatography (HPLC) of 6-gingerol showed a retention time of 9.339 min. Structure of 6-gingerol (C 17 H 26 O 4) was elucidated by proton nuclear magnetic resonance spectroscopy (1 H NMR) and mass spectroscopy (MS). Plane chitosan nanoparticles (PCNPs) and 6-gingerol loaded chitosan nanoparticles (6-GCNPs) were prepared by using ion gelation method. Synthesized nanoparticles were characterized by fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), particle size analyzer, polydispersity index (PI), and zeta-potential (ZP). FTIR analysis showed the presence of various functional groups. The results of SEM and ZP analysis showed that 6-GCNPs have nanoparticle size (196 nm) and stability (-14.1). Our study confirms the easy method for the preparation of 6-gingerol loaded chitosan nanoparticles and put forth the way to evaluate their biological activities.

It is the most serious public health problem and the leading cause of child mortality. About a third of children in developing countries are either underweight or stunted. Micronutrient shortages affect more than 30 percent of the world's rising population. Under nutrition, there is a mechanism whose results are routinely spread not only in later lifestyles, but also into future generations. It is a severe problem that affects children under the age of five in developing countries, resulting in stunted growth, muscle weakness, and underweight. Vitamin and mineral deficiencies are still common, and they frequently occur in conjunction with a general lack of nutrients. Malnourished children are at risk of developing marasmus, kwashiorkor, anaemia, rickets, and blindness. Malnourished children have a higher risk of dying from diarrhoea, malaria, or pneumonia than children with perfect nutritional status. Ef...

Dietary fiber is a part of plant material in the diet, which is resistant to enzymatic digestion. These materials embrace polysaccharides, non-cellulosic polysaccharides like hemicellulose, cellulose, pectic gums, mucilage and a non-carbohydrate component lignin. The diets rich in fibre like whole cereals, nuts, fruits and vegetables have a positive effect on health since their consumption daily has been related to prevention of different non-communicable diseases. Emerging eating lifestyle has contributed to the chronic diseases such as obesity, cardiovascular diseases, aging and others. The consumption of healthy foods daily is a best solution against these diseases. Dietary fibre rich foods associated with physiological actions in the small and large intestine, having important implications in human health. These properties include water dispersibility and solubility, viscosity effects, bulk, absorption, fermentability, and binding of other harmful compounds such as cholesterol, sugars and fat. These properties may lead to various physiological actions such as reducing cholesterol and alleviating blood glucose elevation, maintaining gastrointestinal health and positively affecting calcium bioavailability and immune function. Furthermore, based on their physiochemical properties, many of the new sources of dietary fibre can help to improve the health benefits of new generations as well as adults. This review aiming to open peoples mind on the health benefits associated with dietary fibers and the way non-communicable diseases can be avoided through consumption of food fibers from different sources.
