With ever increased food processing in the new millennia, production of agro-industrial waste has been increased tremendously. Although, these waste are rich sources of essential bioactive compounds. In developing countries, the waste materials from agro-industries can help to obtain valuable components. The objective of this manuscript is to manage industrial potato peel waste and to highlight its nutritional and industrial uses. Potato peel waste, by various procedures such as fermentation, extraction and other treatments, can ensue into the products such as bio-fuels, dietary fibre, biofertilizer, biogas, biosorbent, antioxidants and food additives. This paper enlightens the application of potato peel utilization in food and nonfood purposes for example extraction, utilization of bioactive components, biotechnological usage, livestock feed and miscellaneous use. The present article summarized the literature pertaining to the studies of the last twenty years.

Gut microbiota interacts with host epithelial cells and regulates many physiological functions such as genetics, epigenetics, metabolism of nutrients, and immune functions. Dietary factors may also be involved in the etiology of colorectal cancer (CRC), especially when an unhealthy diet is consumed with excess calorie intake and bad practices like smoking or consuming a great deal of alcohol. Bacteria including Fusobacterium nucleatum, Enterotoxigenic Bacteroides fragilis (ETBF), and Escherichia coli (E. coli) actively participate in the carcinogenesis of CRC. Gastrointestinal tract with chronic inflammation and immunocompromised patients are at high risk for CRC progression. Further, the gut microbiota is also involved in Geno-toxicity by producing toxins like colibactin and cytolethal distending toxin (CDT) which cause damage to double-stranded DNA. Specific microRNAs can act as either tumor suppressors or oncogenes depending on the cellular environment in which they are expressed. The current review mainly highlights the role of gut microbiota in CRC, the mechanisms of several factors in carcinogenesis, and the role of particular microbes in colorectal neoplasia.

Asiatic acid (AA) is a natural aglycone of pentacyclic triterpenoids and is abundantly present in many edible and medicinal plants, including Centella Asiatica, which is a reputed herb for wound healing and neuropsychiatric disorders in many traditional medicine formulations. Asiatic acid has various pharmacological functions such as antioxidant and anti-inflammatory and controls apoptosis, which in numerous diseases credits to its medicinal impact. In preclinical trials, asiatic acid demonstrated potent antihypertensive, neuroprotective, cardioprotective, antidiabetic, antimicrobial, and antitumor behaviors. It has been shown to influence multiple enzymes, receptors, growth factors, transcription factors, apoptotic proteins, and cell signaling cascades in several in vitro and in vivo experiments. This review aims to reflect the current therapeutic potential reports and the underlying pharmacological and molecular mechanisms of asiatic acid. In various diseases, studies display Asiatic acid’s polypharmacological properties, therapeutic ability, and molecular pathways. With the available research data, asiatic acid appears to be a significant multi-targeted, natural-origin polypharmacological agent for further pharmaceutical production and clinical use. Provided advantageous pharmacokinetics, protection, and effectiveness, along with commonly used modern drugs. Asiatic acid may be a potential agent or adjuvant, with a pharmacological justification for its usage in therapeutics.
