ABSTRACT
Introduction@#In recent years, some species of plants that are used in traditional medicine and have high practical value have been successfully introduced in our country. It is necessary to carry out phytochemical studies of local medicinal and useful plants to produce food and biologically active food supplements. The tall coin flower (<i>Inula Helenium</i> L.) has been successfully cultivated in Mongolia, and the lower layer of the plant such as roots and stems are used. However, most of the times the top layer of the plant is not used and thrown away, that is why the plant must be fully utilized. Therefore, the aim of this study is to analyze the top layer of the plant and present the results of anatomical studies.@*Methods@#Remove the top layer of the plant and soak it in glycerin for 24 hours. When making an incision, select a green, undamaged part of the plant and place it in the VCM-202III freezer microtome. Chloral hydrate liquid should be used for micro-preparation. In addition to implementing chloral hydrate solution, use the solutions of various concentrations of sodium alkali (NaOH) (5- 15%). Place the slice in alcian blue stain (using the cell wall staining method) for 3 minutes and wash it with distilled water. Then stain it in a drop of safranin staining (0.5–1.0% aqueous solution) for 1 minute. Rinse it twice with distilled water, add a mixture of glycerin and distilled water, cover it with a glass slide and prepare a temporary slide. Examine the prepared temporary slide with a NOVEL light microscope. Cell images of the plant’s anatomical structures are captured on a computer screen with the help of a digital camera.@*Conclusion@#The anatomy of the leaves, stems and flowers of the tall coin flower (<i>Inula Helenium</i> L.), a plant cultivated in Mongolia, has been analyzed.
ABSTRACT
Inula helenium L. is rich source of eudesmane-type sesquiterpene lactones, mainly alantolactone and isoalantolactone, which have the various pharmacological functions. In this study, we examined the inhibitory effects of nitric oxide (NO) production of hexane, methylene chloride, ethyl acetate, butanol, and water fractions from I. helenium and investigated the anti-inflammatory effect of hexane fraction of I. helenium (HFIH) in LPS-induced RAW 264.7 cells. Quantification of alantolactone and isoalantolactone from HFIH was carried out for the standardization by multiple reaction monitoring using triple quadrupole mass spectrometer. HFIH significantly inhibited inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) protein as well as their downstream products NO and prostaglandin E₂ (PGE₂) in LPS-stimulated RAW 264.7 cells. Moreover, HFIH suppressed NF-κB transcriptional activity by decreasing the translocation of p65 to the nucleus. The in vivo study further confirmed that HFIH attenuated the paw edema induced by carrageenan in an acute inflammation model. These findings suggest that HFIH may be useful as a promising phytomedicine for inflammatory-associated diseases.
