The aim of this study is to provide a review of the research studies that took place in the previous years regarding Mangiferin and its potential use in the treatment of various disorders such as diabetes, cardiovascular diseases, cancer and human immunodeficiency virus.

Mangiferin can be easily extracted from the plant at a very low cost to treat some common as well as deadly diseases, which will be a miracle in herbal treatment. In support of this, the recent related articles were considered to understand the bioactive compound “Mangiferin” to treat lifestyle diseases. Various review articles and research papers were collected from international and national journals, and internet sources were also being used to compile the current manuscript.

Mangiferin has been shown to have the potential to mitigate many life style diseases such as diabetes, obesity, hypertension, fatty liver, atherosclerosis, dyslipidemia and diabetes-related end-organ complications such as retinopathy, neuropathy and nephropathy.

In this comprehensive review, this study evaluates Mangiferin and its lifestyle disease-modifying properties for nutraceuticals purposes.

The present study was carried out to determine (1) essential minerals, total polyphenols, total flavonoids, moisture and ash of four selected South African herbal teas and (2) the effect of blending bush tea with other known commercial herbal teas.

The method used to determine moisture and ash contents followed that of the Association of Official Analytical Chemists (AOAC). Nine minerals were analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES). The total phenolic and flavonoid contents were determined by Folin–Ciocalteu assay and aluminum chloride colorimetric assay, respectively.

The results of the study demonstrated that bush tea had a high ash content of 8.01% and special tea (9.23%), while honeybush (1.96%) and rooibos tea (2.17%) exhibited a low ash percentage. The mineral content was higher in bush tea and special tea than in rooibos tea and honeybush tea except for sodium, which was higher in rooibos tea. The blending of bush tea with special tea improved its potassium content from 22,937.00 mg/kg to 23,379.20 mg/kg. Blending bush tea with rooibos tea at a ratio of 25:75 increased the flavonoid content to 12.21 µg/mL.

The results of the nutrients composition cannot be generalized as it is influenced by other factors such as soil type and seasons.

Increasing the commercialization of indigenous teas.

The results of the study suggest that bush tea and special tea are nutritionally comparable with South African commercial herbal teas. Thus, the consideration for commercialization of these teas is crucial.

This study aims to compare the antioxidant and antimicrobial activity of different parts (tip, mid and base portion) of lemongrass leaves for application as a natural ingredient in the functional drink.

Lemongrass leaf powder was prepared from different parts of leaves and evaluated for nutritional composition. Additionally, the extracts of different portions of lemongrass leaves were analyzed for total phenolics, free radical scavenging activities, ferric reducing antioxidant potential (FRAP) and antimicrobial activities for their application in food products.

Tip portion of lemongrass leaf anticipated significantly (p < 0.05) higher contents of ash, protein, calcium, potassium and iron i.e. 6.2 mg/100 g, 18 mg/100 g, 340 ppm, 819 ppm and 32 ppm, respectively. Maximum (p < 0.05) phenolics (14.7 mg GAE/100 g), 2,2-diphenyl-1-picryl-hydroxyl (86.3%) and FRAP (200 mmol/100 g) were observed in lemongrass leaf tip methanolic extracts. Moreover, lemongrass leaf tip hydro-methanolic extracts portrayed maximum zone of inhibition against E. coli and Staphylococcus aureus i.e. 16.7 and 18.2 mm, respectively.

This study demonstrated higher antimicrobial and antioxidant activities of the tip of lemongrass leaves as compared with mid and base portions, hence suggesting its role in the improvement of physicochemical, antimicrobial and antioxidant properties of food products. Consequently, the application of lemongrass methanolic extract up to 10% remarkably enhanced the nutritional value and sensorial acceptance of the beverages.

The present research draws evidence from laboratory analysis of fresh lemongrass grown in Pakistan. The findings suggest that lemongrass methanolic extracts could be used as a nutritionally rich source of antioxidant activity in functional drinks.

Mango seed, an agricultural food (agri-food) waste obtained during mango processing is generally discarded and causes environmental stress. In the present study, mango kernel was processed into flour and incorporated into macaron formulation. This study aimed to investigate the antioxidant potential, physicochemical properties, and sensory qualities of macaron after substitution of almond flour (AF) with 0% (control, MC-0), 20% (MC-20), 40% (MC-40), 60% (MC-60), 80% (MC-80) and 100% (MC-100) (w/w) of mango kernel flour (MKF).

Sensory evaluation was conducted using a nine-point hedonic scale (n = 90 young adults) to evaluate the acceptance towards MC-0 (control), MC-20, MC-40, MC-60, MC-80 and MC-100 macaron shells (without mango-flavoured ganache). The most preferred formulated and control macarons were subjected to proximate analyses according to the methods of Association of Official Analytical Chemists for moisture, ash, and protein, and American Oil Chemists' Society for fat. Carbohydrate content was estimated by difference. Physical analyses such as colour, pH and water activity (a_w) were performed using various instrumental techniques. Antioxidant activity of all macaron shell formulations was accessed using 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH-RSA). Sensory evaluation was repeated using a five-point hedonic scale to determine the acceptance of the most preferred macaron (with mango-flavoured ganache) among consumer panels of all age groups (n = 80).

The first sensory acceptance test revealed that macaron shell with 40% MKF substitution (MC-40) was the most preferred formulation among young adults aged 18–35 years old. Moisture and ash contents between MC-0 and MC-40 were found to be similar (p > 0.05), while significant differences (p < 0.05) were observed for the fat and protein contents. Antioxidant activity increased proportionally with increasing MKF substitution and exhibited significant improvement (p < 0.05) in MC-40. Approximately 93% of the panellists expressed their liking towards MC-40 in the second sensory acceptance test. Overall, this study demonstrated that 40% MKF substitution in macaron improved its antioxidant performance without compromising consumers' acceptance.

This innovative research features the incorporation of MKF in the development of an economical and healthier macaron. The results constitute industrial relevant findings pertaining to its application feasibility and nutritional properties. This research has contributed knowledge to the existing literature as well as benefitted food manufacturers to develop value-added products that could meet the needs and expectations of interested parties, including consumers, governmental organisations, health-cautious advocates and healthcare providers.

For the prevention and cure of disease, patient use various types of chemical and drug agents. Along with their curative effect, almost all drugs have some destructive effects and side-effects. Due to the minimal and/or none of unwanted side-effect, recently, the use of herbal remedy as the drug of choice becomes the preference choice. The mangosteen, Garcinia mangostana, contains various types of polyphenols. It has been used as a traditional medicine from the ancient times till present days. The purpose of this paper is to investigate the biological properties of mangosteen in relation to health promotion effects.

Several research papers from well-known database (such as PubMed, Google scholar, Scopus and Sciencedirect) were reviewed without considering publication-times to understand the biological properties of mangosteen.

Mangosteen and its xanthone exerted diverse biological activities such as anti-oxidant, anti-inflammatory, anti-allergy, anti-bacteria, anti-fungal, anti-malaria, anticancer and anti-diabetes.

Based on these studies, mangosteen is beneficial dietary supplement of overall human health.
