New Treatments

Diseases mediated by the immune system are difficult problems to treat such as human immunodeficiency virus (HIV) and other lethal viruses. Infections that occur in normal people are generally brief and rarely leave permanent damage. Treatment of this disease requires an aggressive and innovative approach to the development of new treatments so that it requires the role of immunomodulators to improve the immune system. A substance that acts as an enhancer or immune enhancer can be obtained by using herbs that are efficacious as immunostimulants. One of the herbs used is herbal binara (Artemisia vulgaris L) which has been studied as a potential immunomodulator with high antioxidant activity. Previous research also stated that red shoots (Syzygium oleana) were studied as potential immunomodulators with high antioxidant activity. Several other species such as Syzygium samarangense have 16 flavonoida compounds which show pharmacological immunological activity. The purpose of this study was to determine the content of secondary metabolites of ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) and to determine the best dose of extract from the ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) can reduce the volume of swelling of mouse feet. Examination of the chemical content of secondary metabolites from the ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) is carried out by chemical screening and characterization of simplicia and extract. The method used is the slow type hypersensitivity method. In this test the independent variable is the secondary metabolite of ethanol extract of herb binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) with four concentrations (50, 100, 200 and 400 mg / kgBB). The positive control used by Stimuno dose is 32.5 mg / kgBB

The aim of this study was to determine the phenolic content and antioxidant activity of extracts obtained from herb of Tanacetum vulgare L. (tansy) harvested in two different locations from the western part of Romania. Aqueous extracts of tansy presented high antioxidant activity that ranged between 295.77 and 653.65 mg GAE/L, and remarkable percentage of inhibition (31.82-65.05 %). The compounds quantified in the plant extracts that were determined by UHPLC are: ascorbic acid, riboflavin, pyrocatechol, rutin, quercetin, and kaempferol. Extracts obtained from tansy flowers showed higher content of phenols compared to that obtained from leaves. Similarly, the flower extracts present a high antioxidant activity that could suggest their use as natural additives in food preservation and also in pharmaceutical industry and veterinary medicine.

Mistletoe Extracts

The content of plant secondary metabolites is not stable, and factors such as the region/location effect and seasonal variations have an impact on their chemical composition, especially in parasitic plants. Research in this area is an important step in the development of quality parameter standards of medicinal plants and their finished products. The effects of the time and place of harvest and the host tree species on the chemical composition and antioxidant activity of mistletoe extracts were investigated. Statistical tools were used to evaluate the results of the spectrophotometric and LC-ESI-MS/MS studies of the phenolic composition and antioxidant activity. The investigations indicate that the qualitative and quantitative composition, influencing the biological activity of mistletoe extracts, largely depends on the origin of the plant. The mistletoe extracts exhibited a rich phenol profile and high antioxidant activity. The chemometric analysis indicated that mistletoe collected from conifers (Viscum abietis and Viscum austriacum) had the most advantageous chemical composition and antioxidant activity. Moreover, the chemical profile and biological activity of the plant material were closely related to the climatic conditions and location of the harvested plant. Higher levels of phenolic compounds and high antioxidant activity were found in extracts obtained from plant material collected in cold weather with the presence of snow and less sunshine (autumn–winter period).
