Portulaca oleracea belongs to the family of Portulacaceae in the traditional system of medicine and consists of large number of various medicinal and pharmacological importances hence represents a priceless tank of new bioactive molecules. Portulaca oleracea consists of number of pharmacological activities like antimicrobial, antioxidant, antidiabetic, neuronal, antinociceptive and anti-inflammatory activity. This review helps to create an interest in Portulaca oleracea in developing new formulations with more therapeutic and economic value.

Millets are a traditional staple food of the dryland regions of the world and are rich in essential nutrients like protein, fatty acids, minerals, vitamins, and dietary fiber. Also, millets commonly synthesize a range of secondary metabolites to protect themselves against adverse conditions. These factors are collectively termed anti‐nutritional factors and the existence of these factors in millets might reduce the accessibility of the nutrients in humans. Some of these factors include protease inhibitors, tannins, non‐starch polysaccharides‐glucans, phytates, and oxalates each of which might directly or indirectly affect the digestibility of nutrients. Methods like soaking, germination, autoclaving, debranning, and the addition of exogenous enzymes have been used to reduce the anti‐nutritional factors and elevate the bioavailability of the nutrients. This review summarizes various methods that have been used to improve nutrient bioavailability, specifically emphasizing the use of enzymes to improve nutrient bioavailability from millets. © 2021 Society of Chemical Industry.

Fruits are colorful, flavorful, and nutritious components and play an important role for the vital health and maintenance of our body. Experimental evidences suggested that fruits contain various bioactive constituents including flavonoids, polyphenols, carotenoids, and micronutrients such as vitamins and minerals. Because of these, fruits are receiving greater attention to treat and/or control various health complications such as diabetes, obesity, cancer, cardiovascular disease, immune system decline, and certain neurological disorders. Experimental evidences from various in vitro and in vivo imply that fruit extracts and/or isolated bioactive compounds are associated with antioxidant, anti-inflammatory, antimicrobial, cardioprotective, and neuroprotective properties. Therefore, fruits have the potential to be converted into functional foods as well as pharmaceuticals to prevent or/and treat several chronic complications. In the present article, we review current knowledge about the bioactivities and health benefits of selected Indian fruits for the treatment/management of the chronic health complications in humans. Practical applications This review provides practical information about how best to take advantage of the bioactive compounds and health implications of the South Indian fruits like Bael, Jujube, Cotton Candy Berry, and Manilla Tamarind as a potential source of functional and nutritive compounds. It aims at emphasizing the most recent findings on biological effects of major groups of fruits like Bael, Jujube, Cotton Candy Berry, and Manilla Tamarind and their major components, their medical interest, potential drug interaction, notably for human nutrition, health benefits, and therapeutic impacts.
