Nutraceuticals: Pharmacologically Active Potent Dietary Supplements.

A growing demand exists for nutraceuticals, which seem to reside in the grey area between pharmaceuticals and food. Nutraceuticals, up today, do not have a specific definition distinct from those of other food-derived categories, e.g.

Paving Luteolin Therapeutic Potentialities and Agro-Food-Pharma Applications: Emphasis on Pharmacological Effects and Bioavailability Traits.

Luteolin is a naturally occurring secondary metabolite belonging to the class of flavones. As many other natural flavonoids, it is often found in combination with glycosides in many fruits, vegetables, and plants, contributing to their biological and pharmacological value. Many preclinical studies report that luteolin present excellent antioxidant, anticancer, antimicrobial, neuroprotective, cardioprotective, antiviral, and anti-inflammatory effects, and as a consequence, various clinical trials have been designed to investigate the therapeutic potential of luteolin in humans.

Antibacterial activity and phytochemical characterisation of Saussurea gossypiphora D. Don.

The study demonstrates that S. gossypiphora contain number of secondary metabolites such as steroids, tannins, flavonoids, phenolics, carbohydrates, saponins, and amino acids. Methanolic extract (MESG) of the plant contained highest quantity of phenolics, flavonoids and has greater antioxidant, anti-inflammatory and antibacterial activity in comparison to other extracts.

spp.: A Review on Its Immune-Stimulatory and Other Biological Potentials.

In recent decades, interest in the genus has amplified due to its immunostimulatory potential. species, its extracts, and bioactive constituents have been related with cytokine production such as interleukin (IL)-1β, IL-2, IL-6, IL-8, IL-10, IL-12, and tumor necrosis factor (TNF)-α, phagocytosis stimulation of immune cells, nitric oxide production by increasing inducible nitric oxide synthase activity, and stimulation of inflammatory response via mitogen-activated protein kinase pathway. Other pharmacological activities like antioxidant, anti-cancer, antihyperlipidemic, anti-diabetic, anti-fatigue, anti-aging, hypocholesterolemic, hypotensive, vasorelaxation, anti-depressant, aphrodisiac, and kidney protection, has been reported in pre-clinical studies.

Antibacterial potential of Saussurea obvallata petroleum ether extract: A spiritually revered medicinal plant.

Uttarakhand Himalayan region holds Asteraceae or Compositae as the largest family of flowering, medicinal and aromatic plants. Species belonging to this family rises from low altitude to the alpine region. Among Asteraceae, Saussurea obvallata (DC.

Satyrium nepalense, a high altitude medicinal orchid of Indian Himalayan region: chemical profile and biological activities of tuber extracts.

The present study investigated antioxidant and antibacterial activities of 5 different extracts and derived fractions from the S. nepalense tubers. Identification of the most active fractions, their phytochemical characterization, total phenolic and flavonoid contents, and biological activities were also evaluated.

Comparative Evaluation of Polyphenol Contents and Antioxidant Activities between Ethanol Extracts of Vitex negundo and Vitex trifolia L. Leaves by Different Methods.

The in vitro antioxidant potential assay between ethanolic extracts of two species from the genus ( L. and L.) belonging to the Lamiaceae family were evaluated.

Synthesis of the impurities during the manufacture of bulk drug midazolam and separation of these impurities by HPLC.

During the manufacture of bulk drug midazolam various impurities arised that can be the related products or degradation products. Structures of eight impurities that can arise during the manufacture of bulk drug midazolam were proposed. In the present work, synthesis of these impurities and their characterization by different spectroscopic techniques have been done.
