“…The low moisture content (9.6%) in the tea extract (Table ) confirms suggests its capacity for long‐term storage against microbial invasion. The amount of dietary fiber (29.6%) and ash content registered in MLTE is lower than that of mamaki tea leaves but considerably higher than reported amounts in commercial Lipton tea ( Camellia sinensis ) (Kartika, Shido, Nakamoto, Li, & Iwaoka, ), which can contribute to the daily needs of fiber to reduce the risk of diabesity, cancer, and cardiovascular diseases without causing bowel irritation (Theuwissen & Mensink, ). The ash content of teas has been reported to be inversely proportional to the total mineral elements and the quality of the tea during storage (Kartika et al, ).…”

“…The crude protein composition of MLTE was comparable with those recorded in the green teas and Lippia multiflora herbal tea grown in Abidjan (Christine, Albert, & Séraphin, ) and within the recommended daily need by the Dietary Reference Intake (DRI, ). Furthermore, the low percentage of fat, cholesterol, and salt in MLTE (Table ) suggests its potential to circumvent the risk of obesity and high blood pressure (Kartika et al, ). The high composition of carbohydrate (73%) in MLTE correlates with its computed energy value (475 kJ/100 g) (Table ), which may serve as a veritable source for a high‐calorie nutrition program.…”

The nutrient composition of Myrothamnus flabellifolius leaf tea extract (MLTE) and its protective effect against oxidative hepatic cell injury were evaluated. Gallic acid, caffeic acid, ferulic acid, methyl gallate, and epicatechin were identified in MLTE by high‐performance liquid chromatography (HPLC). The tea extract showed an appreciable nutritional content of proximate, sugar, vitamin E, monounsaturated fatty acids, omega 6 and 9 unsaturated fatty acids, as well as considerable amounts of various mineral elements. Nineteen amino acids were found. Moreover, MLTE exhibited potent in vitro antioxidant activities, presumably because of its richness in polyphenols (gallic acid and ferulic acid) and vitamin E. In Chang liver cells, pretreatment with MLTE suppressed oxidative lipid peroxidation (IC50 = 113.11 μg/ml) and GSH depletion (IC50 = 70.49 μg/ml) without causing cytotoxicity. These data support the local consumption of M. flabellifolius herbal tea, which may be used against oxidative stress‐induced diseases while providing the body with necessary nutrients. Practical application Herbal teas are one of the most consumed beverages in the world today, due to their refreshing taste and additional health benefits. Myrothamnus flabellifolius herbal tea is a widely used traditional herbal tea in Southern Africa with potentials for commercialization due to its pleasant flavor. This study, for the first time, reported the nutritional composition of the leaf decoction of M. flabellifolius and its protective effect on hepatic oxidative insults. These results can inform the dietary and nutritional use of the tea for optimum benefits, as well as provide preliminary scientific validation of the use of the herbal tea as an antioxidant beverage with good nutritional value.

“…Magnesium content was moderately quantifiable across the compartments of M. sinensis and M. paradisiaca fruits. It has a recommended daily allowance (RDA) of 450 mg [32] and is important for cardiac functioning and stemming the early phase of diabetes [33], nerve impulse transmission, detoxification, and bone and teeth structural strength [34]. Magnesium levels in M. paradisiaca peel were moderate in quantity, just as [35] observed in ripened peel of plantain.…”

Banana and plantain contribute significantly to food security and amelioration of malnutrition, earning their status as staples in several localities of tropical and sub-tropical regions. The distribution of metabolites within the various parts also remains as a key essential to their nutritive and therapeutic potential. This study was aimed at evaluating the nutritional and mineral composition of the flesh, peel, and peel extract components of Musa sinensis L. and Musa paradisiaca L. fruits as well as their nutritional and therapeutic potentials. Proximate and antinutritional analyses were carried out using standard analytical methods of the Association of Official Analytical Chemists (AOAC), while the mineral constituents were evaluated using inductively coupled plasma optical emission spectroscopy (ICP-OES). Proximate analysis revealed that the flesh and peel of M. sinensis L. and M. paradisiaca L. contain substantial amounts of moisture, fiber, carbohydrates, and low fat content, while minerals K, Mg, Ca, Na, P, and N were substantially concentrated in the peels and peel extracts in particular. The antinutrients alkaloid, oxalate, saponin, and phytate were detected in safe amounts according to the World Health Organization (WHO). The study points out that the peel and its derivative extract, as well as the flesh of M. sinensis L. and M. paradisiaca L. are to be put to more relevant human nutritional and therapeutic use.Primary metabolites from plants like fatty acids, carbohydrates, dietary fiber, and amino acids are central in the developmental and physiological processes in plants, while secondary metabolites (e.g., phenolics, carotenoids, sterols) are involved in plant protection and pollinator attraction [9,10].The banana (Musa sinensis L.) and plantain (Musa paradisiaca L.) belong to the Musaceae family and have been available for human use for ages [11,12]. They have marked morphological similarities and are of economic and nutritional value. Banana and plantain are majorly tropical plants, but do not grow in temperate regions. They grow predominantly in the continents of Asia, South America, and the tropical African sub-continent [13]. M. sinensis and M. paradisiaca fruits are essentially good potassium-based dietary items and serve as staples in many global cultures. Potassium is useful in ensuring proper muscular functioning [14]. M. sinensis and M. paradisiaca fruits are utilized in beverage production, especially among subsistence farmers [15], while other parts, including the roots and flowers are medicinally useful.The nutritional and therapeutic values of M. sinensis and M. paradisiaca fruit flesh are undisputedly clear. However, this study was undertaken to evaluate and establish the nutritive, therapeutic, and pharmacological potentials of M. sinensis and M. paradisiaca flesh, peels, and their derivative dietary product, to improve the dietary acceptability and reduce biological wastage respectively of their peels (exocarp).

“…e level of Mg in our study was low compared to the 87 mg/100 g as reported by [42] in Africa. Mg is involved in insulin secretion, many oxidative metabolic enzymatic reactions, reduction of blood pressure, body temperature regulation, nerve impulses transmission, detoxification, energy production, and formation of healthy teeth and bones [43]. Mg is essential and has become the initial treatment in many life-threatening emergency medical conditions.…”

In addition to fiber, Corchorus (jute) leaf is also rich in secondary metabolites and is used in folk medicine in jute-producing communities. It has been reported that jute halts progression of and helps manage different chronic diseases like tumors, obesity, diabetes, and cardiovascular diseases. Various phytochemical, mineral, and antioxidant potency properties of 30 genotypes belonging to Corchorus capsularis and Corchorus olitorius were evaluated in the current study. The results demonstrate that the range of total flavonoids and polyphenols was 3.04 to 13.66 mg rutin equivalent (RE)/g and 5.12 to 7.78 mg gallic acid equivalent (GAE)/g DW, respectively. Total tannin and saponin content in both species was 13.08 to 26.95 mg tannic acid (TAE)/g and 34.45 to 114.59 mg tea saponin (TSE)/g DW, respectively, when analyzed for the first time. Moreover, this study sincerely establishes that jute leaf is a great source of mineral elements (magnesium, zinc, and selenium) and could also be a good energy source. The antioxidant properties of samples were examined with three unique strategies, including DPPH, FRAP, and ABTS values of leaf extract ranging from 206.42 to 351.77 μg/ml (IC50), 16.69 to 94.69 mmol Fe (II)/g DW, and 50.27 to 149.90 mmol trolox equivalent (TE)/g DW, respectively. A principle component analysis (PCA) explained 58.52% of the variance, while a hierarchical cluster analysis (HCA) was performed to construct five distinct groups based on their secondary compound metabolites content and antioxidant activities. Therefore, this study facilitates selection of the high genotypes that might be used as new materials for developing industrial and medicinal uses in addition to sorting genotypes for future genetic engineering purposes in order to enhance a particular bioactive compound and its natural antioxidants that are beneficial for human health.
