Plant-Based Antioxidant Extracts and Compounds in the Management of Oral Cancer

Oral cancer continues to be a leading cause of death worldwide, and its prevalence is particularly high in developing countries, where people chew tobacco and betel nut on a regular basis. Radiation-, chemo-, targeted-, immuno-, and hormone-based therapies along with surgery are commonly used as part of a treatment plan. However, these treatments frequently result in various unwanted short- to long-term side effects. As a result, there is an urgent need to develop treatment options for oral cancer that have little or no adverse effects. Numerous bioactive compounds derived from various plants have recently attracted attention as therapeutic options for cancer treatment. Antioxidants found in medicinal plants, such as vitamins E, C, and A, reduce damage to the mucosa by neutralizing free radicals found in various oral mucosal lesions. Phytochemicals found in medicinal plants have the potential to modulate cellular signalling pathways that alter the cellular defence mechanisms to protect normal cells from reactive oxygen species (ROS) and induce apoptosis in cancer cells. This review aims to provide a comprehensive overview of various medicinal plants and phytoconstituents that have shown the potential to be used as oral cancer therapeutics

Therapeutic Uses of Wild Plants by Rural Inhabitants of Maraog Region in District Shimla, Himachal Pradesh, India

The main aim of this study is to document important ethnomedicinal plants from the Maraog region, located in the district of Shimla in Himachal Pradesh, India. A total of 110 medicinal plant species belonging to 102 genera and 57 families were reported from the study site. All of the species were collected from wild habitats. The rural people of the Maraog region were surveyed through interview methods, group discussions, and participatory observations. In the current study, data were collected from 88 informants through the snowball method. A total of 110 plant species were collected from the study area, including 64 herbs, 24 shrubs, 9 trees, 5 climbers, 3 grasses, and 5 ferns. Most of the plant species, reported from the study area, belong to the Rosaceae and Asteraceae families, each contributing 12 plant species, followed by the Lamiaceae family with 6 plant species. The most used part of the plant in the preparation of herbal medications is the leaves, which have been reported in 62 plants, followed by roots in 14 plants, and flowers and other aerial parts in 9 plants. The ethnomedicinal data were analyzed using “Use Value,” a statistical quantitative method, with Artemisia vestita having the highest use value (1.00), followed by Cannabis sativa (0.79), Rhododendron arboreum (0.79), and Datura stramonium (0.71). Older people were found to have a vast knowledge of wild medicinal plants, while the younger generation’s knowledge was lacking. As a result, traditional knowledge about the use of plants as a source of medicine has decreased day-by-day.Therefore, there is a need to document traditional ethnobotanical knowledge. The data could serve as a basis for research by pharmacological and nutraceutical industries for the development of novel drugs

Moguća uloga izoflavona u uklanjanju nepoželjnog okusa soje, te ključna uloga IFS2 u akumulaciji izoflavona u sjemenkama soje

Research background. Soybean (Glycine max (L.) Merr) is a nutrient-rich crop with a high protein content and various bioactive compounds with health-promoting properties. Nevertheless, it is poorly accepted as a food by consumers due to its off-flavour. Due to the ubiquitous presence of isoflavones in soybeans, their inherent antioxidant potential and inhibitory effect on lipoxygenase activity, their sensory properties are currently being considered to mitigate the off-flavour. Experimental approach. In the present study, the content and composition of isoflavones in 17 soybean cultivars are determined. The correlation between the isoflavone mass fraction and lipid peroxidation was also established, using thiobarbituric acid (TBA) value and carbonyl compound concentration as indices for the development of off-flavour. Cloning, gene expression analysis and in silico analysis of isoflavone synthase isoforms (IFS1 and IFS2) were also performed. Results and conclusions. The total isoflavone mass fraction in soybean genotypes ranged from (153.5±7.2) µg/g for PUSA 40 to (1146±43) µg/g for Bragg. There was a moderately negative correlation between the indices of off-flavour formation and the genistein/daidzein ratio (p<0.1). However, the correlation with total isoflavone mass fraction was found to be insignificant, indicating complex interactions. Higher protein-protein interactions for the predicted structure of IFS2 with other biosynthesis enzymes and its comparatively higher expression in the Bragg than that of IFS1 indicated its more important role in isoflavone synthesis. Novelty and scientific contribution. The genistein/daidzein mass ratio was found to be an important factor in controlling off-flavour. IFS2 was identified as key to produce soybeans with high isoflavone mass fraction and potentially lower off-flavour formation.Pozadina istraživanja. Soja (Glycine max (L.) Merr) je žitarica bogata hranivima, s velikim udjelom proteina i različitih biološki aktivnih spojeva koji imaju pozitivan učinak na zdravlje. Usprkos tome, nije prihvaćena među potrošačima zbog svog nepoželjnog okusa. Budući da su izoflavoni prisutni u soji u velikoj količini, te imaju antioksidacijska svojstva i inhibiraju aktivnost lipoksigenaze, ispituju se njihova senzorska svojstva u svrhu uklanjanja nepoželjnog okusa soje. Eksperimentalni pristup. U ovom su radu određeni udjel i sastav izoflavona u 17 kultivara soje. Korelacija između masenog udjela izoflavona i lipidne peroksidacije utvrđena je testom tiobarbiturne kiseline i mjerenjem koncentracije karbonila kao pokazateljima razvoja nepoželjnog okusa. Osim toga, klonirane su izoforme izoflavon sintaze (IFS1 i IFS2), te je ispitana ekspresija gena i provedena analiza in silico. Rezultati i zaključci. Ukupni maseni udjel izoflavona u soji iznosio je od (153,5±7,2) µg/g u genotipu PUSA 40 do (1146±43) µg/g u genotipu Bragg. Opažena je blago negativna korelacija između indikatora nastanka nepoželjnog okusa i omjera genisteina i daidzeina (p<0,1). Međutim, korelacija s ukupnim masenim udjelom izoflavona nije bila značajna, što potvrđuje kompleksnost interakcija. Čini se da IFS2 ima veću ulogu od IFS1 u sintezi izoflavona, što je vidljivo iz veće interakcije između proteina u predviđenoj strukturi IFS2 i drugih proteina odgovornih za biosintezu izoflavona, te njegove bitno veće ekspresije u genotipu Bragg nego IFS1. Novina i znanstveni doprinos. Maseni omjer genisteina i daidzeina bitno je utjecao na smanjenje nepoželjnog okusa soje. Utvrđeno je da IFS2 ima ključnu ulogu u proizvodnji soje s velikim masenim udjelom izoflavona, što bi trebalo smanjiti nastanak nepoželjnog okusa
