Secondary Metabolites from Ophiorrhiza
Authors: Anil J. Johnson, Renjith Rajan and Sabulal BabyOphiorrhiza is a genus of flowering plants with about 400 species. Phytochemical studies spanning last four decades resulted in the isolation of nearly 100 secondary metabolites, mostly alkaloids and anthraquinones, from various Ophiorrhiza species. This mini review summarizes the phytochemistry, camptothecin (CPT) screening, tissue culture-based CPT source enhancement and biological activities of the genus Oph Read More

Evaluation of Mechanical, Antioxidant and Antimicrobial Properties of Edible film Containing Myrtle Berries Extract
Authors: Wissam Zam and Ali AliBackground: In the last decades, consumers have become more health conscious and their demand for foods without synthetic preservatives has increased. The use of edible films as carriers of natural antimicrobial agents provides a novel way to improve the safety and shelf-life of ready-to-eat foods. These films can reduce surface microbial populations and reduce the need for synthetic packaging materials. Edible films can Read More
