Bioactive compounds, called phytochemicals, are produced as secondary metabolites in plants that have beneficial effects on health when they are consumed as nutrients. Phytochemicals have an effective role in the formation of the color, smell and taste of the plants. As an alternative to the synthetic materials used in the treatment of many chronic diseases, the interest in the use of plants phytochemicals have been increased. This trend has led to the development of a new market. This review includes biological activities of plant phytochemicals including antioxidant, antimicrobial, antifungal, antidiabetic, antiinflammatory, anticancer and antihypertensive properties.

Bioactive Phytochemicals

Lentils have been part of human diet from ancient times. This chapter focuses on the nutritional composition, presence of bioactive substances, antioxidants and health rendering properties of lentils. Recent definitions have considered lentils as a prophylactic and therapeutic functional food due to its considerable content of essential macronutrients, namely functional proteins and carbohydrates, and essential micronutrients, as well as bioactive phytochemicals such as phytates and polyphenols. Indeed, the presence of an impressive arsenal of secondary metabolites, minerals and bioactive constituents in lentils have shown to be promising contributors in the management and prevention of several human chronic diseases, attributed to their anticarcinogenic, hypoglycemic, hypocholesterolemic and blood-pressure lowering properties.

Streptomyces Ghanaensis

Microbial green synthesis of nanoparticles and exploiting them for biological applications has received considerable attention in the recent past. Gold (Au) nanoparticles were synthesised using Streptomyces ghanaensis sp. VITHM1 (MTCC #12465) biomass and evaluated for its cytotoxic activity. Au NPs were synthesised after 56 h of incubation of cell free supernatant with 1 mM HAuCl4 at room temperature. The synthesized NPs were characterized by UV-visible spectrum, X-ray diffraction (XRD), atomic force microscopy, scanning electron microscopy equipped with energy dispersive spectroscopy, transmission electron microscopy, fourier transform infrared spectroscopy, dynamic light scattering (DLS) and zeta potential. The synthesised gold nanoparticles were highly stable, spherical in shape and the average size was 30-50 nm. The secondary metabolites present in the biomass were identified by gas chromatography-mass spectrometry (GC-MS). The mechanism of formation of gold nanoparticles with the two major secondary metabolites present in the extracted biomass was proposed. The 3D structure of the unit cell in the synthesized nanoparticles was determined by XRD data base. The synthesized gold nanoparticles  (200 µg/mL) exhibited admirable cytotoxic activity by inducing apoptosis in Hep-2 cells after 48 h of incubation. Gold nanoparticles (250 µg/mL) did not cause any haemolysis on human red blood cells. These results of this study suggest that Streptomyces biomass- mediated gold nanoparticles can be explored for cytotoxic activity

In western countries, Red Raspberry is the most common fruit used for its medicinal and therapeutic activity. Red raspberries are the good sources of antioxidant polyphenols which have wonderful preventive action against chronic diseases. Ellagitannins and anthocyanins are the most important polyphenolic components of raspberries that have most effective anti-oxidant action. Besides secondary metabolites i.e. phytochemical in the form of polyphenols, Red Raspberries also have presence of various crucial micronutrients like fibers, vitamin C and potassium. Although literature shows very few human studies, we review and summarize some available writings that clarify the potential health benefits and antioxidant action of major polyphenols of red raspberries.
