Authors:Mamedov; Nazim et al. Abstract: Medicinal plants and preparations derived from plants in the Caucasus and North America regions have for a long time been used for the treatment and prevention of virtually all human afflictions. Even today, countries and people of these areas continue to test and use plants as medicine. Indeed, the study and application of medicinal plants and plant extracts has formed the basis for treatment of several diseases, pain, and other afflictions. Research has revealed that many plants synthesize and accumulate natural constituents that have active physiological and psychological effects on the human body. A number of plant extracts that have been used as medicines over hundreds of years are constituents in most modern prescription drugs. The arrays of environments within the Caucasus Mountains and North America have produced a diverse flora with an assortment of medicinal properties. Due to curative powers, a number of these plant species continue to be used in folk medicines. PubDate: Tue, 29 Dec 2015 14:16:07 PST
Authors:Shrestha; Samon et al. Abstract: Leaves of Tabebuia bahamensis, collected on Abaco Island, Bahamas, were dried and extracted with dichloromethane to yield a crude extract. Using preparative flash column chromatography on silica gel, enabled the isolation of ursolic acid with an excellent yield of 2.06 percent based on the mass of dry leaves. Both the crude leaf extract and ursolic acid produced selective in-vitro cytotoxic activity on tumor cells from human mammary and bladder tissue. Ursolic acid also demonstrated antibacterial activity against Staphylococcus aureus. PubDate: Tue, 29 Dec 2015 14:16:05 PST
Authors:Eldanasoury; Mohamed et al. Abstract: To distinguish among five lupine (Lupinus termis L.) genotypes, biochemical markers and seedling characteristics were studied, using electrophoresis of seed and leaf proteins and four isozyme systems[esterase (EST), catalase (CAT), peroxides (Prx), and glutamate oxaloacetate transaminase (GOT)]. A total of 21 and 13 polymorphic bands were detected in the seed and leaves, respectively. Molecular weights ranged from 183.82 to 11.14 kDa for the seeds and 148.52 to 8.17 for the leaves. Among the genotypes, seed storage protein bands ranged from 10 in genotype Giza-1 to 13 in genotype Giza-3, while the total number of leaf protein bands ranged from six in genotype Giza-2 to nine in genotype Giza-1. Specific, characteristic bands could be used to identify and differentiate some genotypes from among others. At the isozyme level, a similar number of bands were produced, but the location and Rf values of the bands differed, enabling identification among the lupine genotypes.

Authors:Phoboo; Susanna et al. Abstract: Aizoon canariense, Cynomorium coccineum, Glossonema edule, and Malva parviflora, edible desert plants from Qatar, were selected to determine levels of phenolic bioactives and potential health benefits for managing early stages of type 2 diabetes and hypertension. Aqueous extracts of C. cocineum, contained soluble phenolics and had relatively high levels of antioxidant activity associated with α-glucosidase, α-amylase, and angiotensin-converting enzyme (ACE). G. edule and M. parviflora had moderate levels of anti-oxidant potential, soluble phenolics, and ACE inhibitory activity. The medicinal properties associated with C. coccineum suggest the plant may have potential as a diet-based solution for combating, preventing, and managing the early stage of type 2 diabetes when coupled with an overall healthy life style and pharmacological management strategies.
