ABSTRACT
Introduction@#According to the annual health report of Mongolia, non-communicable diseases are rising. Digestive system diseases, the second leading cause of morbidity in the population, account for an average of 15.5 percent of all morbidity over the last 10 years. In traditional Mongolian medicine, <i>Plantago Major</i> L has been widely used as a remedy for wound healing, cholangitis, gastric and duodenal ulcers.@*Material and method@#The research was conducted in the pharmaceutical industry and technology laboratory. The leaves of <i>Plantago Major</i> L were chosen as the main raw materials and UV spectrophotometer, shaker, thin-layer chromatographic plates (Silica gel 60 F 254, Germany), and UV light were used in the experiment. The leaves of <i>Plantago Major</i> L were extracted with 40% ethyl alcohol in a soxlet apparatus and evaporated in a vacuum evaporator to obtain a thick extract.@*Result@#Thin-layer chromatographic analysis of granule and ethyl alcohol extracts of <i>Plantago Major</i> L revealed yellow-brown spots (Rf = 0.4) at the same level as the standard substance rutin on the plate, indicating the presence of flavonoids. The highest light absorption was 250 nm when determining the sensitive wavelength of ethyl alcohol extract of <i>Plantago Major</i> L between 200 nm and 520 nm. The total flavonoids contained 3.95 ± 0.17% (p <0.001) in 40% ethyl alcohol extract of <i>Plantago Major</i> L.@*Conclusion@#It was detected that quantitative mass of total flavonoids in liquid extracts from was 3.95±0.17%.
ABSTRACT
Background: Use of predominantly anaerobic energy systems such as that seen in 800-meter athlete runners disrupts mitochondrial function as an energy source. Furthermore, it produces free radical substances and causes myocyte damage. Malondialdehyde (MDA) plasma concentrations correlate with free radical levels and are therefore predictive of cell damage. Objective: To analyse the effect of flavonoid antioxidant from chocolate bean extract for prevention of lipid peroxidation of myocyte membranes caused by free radical substances in athletes partaking in predominantly anaerobic sports. Materials and Methods: The study of population consisted of 16 junior athletes who compete in 800-meter races. This was a randomized experimental study. Subjects were divided into two groups, chocolate bean extracts and placebo groups, and then practiced regularly for 14 days. All subjects were assessed on day 15. Results were analysed statistically using paired t test, ANOVA and Duncan tests. Results: Concentrations of MDA were reduced in flavonoid group. Conclusion: Flavonoid antioxidant from chocolate bean extract may prevent myocyte damage was caused by reperfusion injury.
