Moringa oleifera Lam. ( M. oleifera ), which belongs to the Moringaceae family, is a perennial deciduous tropical tree, and native to the south of the Himalayan Mountains in northern India. M. oleifera is rich in proteins, vitamin A, minerals, essential amino acids, antioxidants, and flavonoids, as well as isothiocyanates. The extracts from M. oleifera exhibit multiple nutraceutical or pharmacological functions including anti-inflammatory, antioxidant, anti-cancer, hepatoprotective, neuroprotective, hypoglycemic, and blood lipid-reducing functions...

Curcumin is a bioactive phytochemical that can be utilized as a nutraceutical or pharmaceutical in functional foods, supplements, and medicines. However, the application of curcumin as a nutraceutical in commercial food and beverage products is currently limited by its low water-solubility, chemical instability, and poor oral bioavailability. In this study, all-natural colloidal delivery systems were developed to overcome these challenges, which consisted of saponin-coated curcumin nanoparticles formed using a pH-driven loading method...

The red maple (Acer rubrum) species is economically important to North America because of its sap which is used to produce maple syrup. In addition, various other red maple plant parts, including leaves, were used as a traditional medicine by the Native Americans. Currently, red maple leaves are being used for nutraceutical and cosmetic applications but there are no published analytical methods for comprehensive phytochemical characterization of this material. Herein, a rapid and sensitive method using liquid chromatography with electrospray ionization time-of-flight tandem mass spectrometry was developed to characterize the phenolics in a methanol extract of red maple leaves and a proprietary phenolic-enriched red maple leaves extract (Maplifa™)...

Consumers are aware of diet causing health problems and therefore there is an increased demand for natural ingredients that are expected to be safe and health-promoting. Many of these compounds belong to the class of flavonoids and can be divided into these five groups: flavanones, flavones, flavonols, flavanols, isoflavones and anthocyanidins. Extracts from citrus fruits are usually used as functional ingredients for several products. The aim of this paper was to develop an UHPLC-UV-ESI-HRMS method to define the metabolite profile of different parts of citrus fruit, of a particular cultivar called 'Ovale Calabrese', and in its main by-products...

BACKGROUND: Uses of polyherbal formulations have played a major role in traditional medicine. The present study is focused on the formulations used in traditional Thai folkloric medicine as tonics or bracers. Twenty documented polyherbal mixtures, used as nourishing tonics by the folk healers in Phatthalung and Songkhla provinces in southern Thailand, are targeted. Despite traditional health claims, there is no scientific evidence to support the utilization of polyherbal formulations...

Sugarcane is an important crop grown in tropical regions for sugar, and for ethanol production. Sugarcane is also a source of phytochemicals but its nutraceutical potential has been under-explored. We show that ethanol extracts of whole dried sugarcane (WDS) recovers a rich content of polyphenols, flavonoids and antioxidant activity that act on inflammatory mediator proteins. To investigate the mechanisms of this activity, we stimulated SW480 colon cancer cells with lipopolysaccharide, exposed cells to WDS and quantitated changes to the proteome and phosphoproteome using label-free mass spectrometry...

This main focus of this study was to evaluate the thermal degradation kinetics and the phytochemical characterization of the elderberries extract. Pelargonidin-3-sophoroside and delphinidin-3-glucoside were identified as the major anthocyanin compounds and catechin hydrate as the major flavonoid compound. In order to further understand the action of the heat treatment on the bioactive compounds from elderberry extract, fluorescence studies were also carried out. In general, heating at temperatures ranging from 100 to 150 ℃ for up to 90 min caused a decrease in fluorescence intensity, simultaneously with significant redshifts in λmax suggesting important molecular changes inside the anthocyanins structure, affecting the antioxidant activity...

Legume sprouts are considered natural, healthy products that provide a source of bioactive compounds to fight against chronic diseases. This study aims to identify the optimal germination temperature (GT) and germination time (Gt) to maximize total phenolic and flavonoid contents (TPC, FC), and antioxidant activity (AoxA) of desi chickpea. Response surface methodology was used as an optimization tool. An experimental design with two factors (GT and Gt) and five levels was used (13 treatments). The sprouts from each treatment were lyophilized, tempered, and milled to obtain germinated chickpea flours (GCF)...

Beyond the well-known effects on cognitive impairment of the Mediterranean diet, a number of studies have investigated the possible action on cognitive decline of different botanicals and phytochemicals, most of which are well-known anti-inflammatory or antioxidant agents with a good tolerability and safety profile. In particular, the current literature supports the use of Ginkgo biloba, resveratrol, epigallocatechin-3-gallate and l-theanine, Theobroma cacao, Bacopa monnieri, Crocus sativus and curcumin, which might have a positive impact on cognitive impairment used alone or in combination with other nutraceuticals or traditional drugs...

Plants are the source of various natural compounds with pharmaceutical and nutraceutical importance which have shown numerous health benefits with relatively fewer side effects. However, extraction of these compounds from native producers cannot meet the ever-increasing demands of the growing population due to, among other things, the limited production of the active compound(s). Their production depends upon the metabolic demands of the plant and is also subjected to environmental conditions, abundance of crop species and seasonal variations...
