The chromatographic study of fagopyrum methanol extract / Siti Zainab M. Yassin

Medicinal plants have been greatly discovered by the researchers from around the world because of its contribution in treating and preventing disease in human body. Medicinal plants also can provide good health to human. Since the modern medications nowadays contain many chemicals, the medicinal plants are said to be the suitable replacement for those medication that contain chemical that will affect the body. So, the scientists are giving their full attention to do research about the plants by using various types of modern equipment in order to prove the benefits of the plants. In this study, the investigation of Fagopyrum esculentum Moench (common buckwheat) was restricted to the constituents that contain in the methanol extract of the seeds. All over the world, the benefits of the Fagopyrum esculentum Moench is said to be approved, so further study about this plant is considered to be attention grabbing. The objectives of this experiment are to investigate the traditional and medicinal values of common buckwheat and to compare the common and tartary buckwheats' contribution in preventing human disease. In addition, the objectives are to review the scientific evidence on the health effect of common buckwheat and to screen the phytochemicals in Fagopyrum esculentum. From the literature, common buckwheat is said as a healthful pseudocereal, has good amino acid and vitamins. It also has antioxidant activity and variety of bioactivities. In comparison, between common and tartary buckwheat, tartary buckwheat provides more medicinal benefit to human in terms of its rutin and other polyphenols content. The unsaturated fatty acids, protein content and vitamin B was higher in tartary than in common buckwheat. It can be said that tartary is an excellent food material compared with common buckwheat. In this experiment, the analytical and preparative TLC were used for the detection of compound. Furthermore, the Nuclear Magnetic Resonance spectroscopy is also used to identify the compound in common buckwheat. Finally, a fatty acid ester was identified as the derivative of the oleic acid. It can provides its own beneficial value to human · health. In conclusion, this study successfully met the objectives.
