In vivo and in vitro Study of Piper longum Explants for Anticancerous, Antibacterial and Antioxidant Properties | Chapter 3 | Current Strategies in Biotechnology and Bioresource Technology Vol. 1


Piper longum is a medicinal plant of great importance. The present work is to compare anticancerous, antibacterial and antioxidant properties of different explants (leaf and stem) of Piper longum in vivo and in vitro. The anticancerous activity was measured in terms of percentage cytotoxicity and the cell line used was leukemic cell line K562. Escherichia coli, Bacillus subtilis and Staphylococcus aureus, bacteria were used for determination of antibacterial activity. Solvent extracts were prepared from leaf and stem explants of Piper longum and their anticancerous, antibacterial and antioxidant activities were evaluated. Antioxidant activity was measured in terms of percentage (%) Total Phenolic Content (TPC) and percentage (%) 2,2– diphenyl 1-2-picryl hydrazy1 (DPPH) radical scavenging capacity. The aqueous Piper longum fruit extract and green synthesized silver nanoparticles showed powerful antioxidant properties in in vitro studies. The anticancerous, antibacterial and antioxidant effects were found to be higher for hot extracts than cold extract. Further the results of in vivo explants were better than in vitro explants, in case of anticancerous activity and results of in vitro explants were better than in vivo explants, in case of antibacterial and antioxidant activity.

Consensus Summit: Lipids and Cardiovascular Health in the Nigerian Population | Chapter 09 | Current Trends in Food Science Vol. 1

Aims: To issue a consensus statement on Lipids and Cardiovascular Health and the impact of their interrelationship in Nigerian Population. Study Design: Experts from a range of relevant disciplines, deliberated on different aspects of Lipids and Cardiovascular Health in the Nigerian Population at a Summit. Place and Duration of Study: The Summit was held in April 2016 at the Nigerian Institute of Medical Research. Methodology: Presentations were made on central themes after which expert participants split into four different groups to consider the questions relevant to different sub themes of the title. Consensus was arrived at, from presentations of groups at plenary. Conclusion: With the increase in the prevalence of NCDs, especially Cardiovascular Disease in Nigeria, and the documented evidence of deleterious effects of lipids, the expert panel called for an urgent need to advocate for the general public and health professionals to make heart-friendly

A Review on Gongronema latifolium, an Extremely Useful Plant with Great Prospects | Chapter 11 | Recent Advances in Biological Research Vol. 3

Gongronema latifolium is a plant that has a wide range of nutritional and ethnomedical uses in different tropical African communities. Scientific reports on the chemical composition and bioactivity (anti-inflammatory, antimicrobial, antidiabetic, antioxidant, anticancer and allelopathic properties) of the plant material by different authors are discussed in this review. Future prospects of the plant extracts in the areas of herbal formulations, food preservation, alcoholic fermentation and beer production, drug discovery and allelopathy are also highlighted.

An Overview of Ultrasonic Technology and Its Applications in Food Processing, Preservation and Quality Control | Chapter 03 | Current Research in Science and Technology Vol. 3

Ultrasound is one of the emerging technologies that were developed to minimize processing, maximize quality and ensure the safety of food products. In recent years, ultrasound technology has been used as an alternative processing option to conventional thermal approaches. Although Ultrasonication methods have been used for years in research and diagnostics, major advances have been made in the last decade. The applications for which high power ultrasound can be used range from existing processes that are enhanced by the retrofitting of high power ultrasonic technology, to the development of processes up to now not possible with conventional energy sources. The present paper reviews the generation, principle mechanism, properties, process parameters, applications, merits and demerits and future trends of the ultrasound technology in the food processing.
