The study of some biologically active substances in liquid extract’s from Plantago Major.L / Монголын эм зүй, эм судлал

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%.
