"Astragalus Membranaces Bunge", which is a medical herb, grows wild in Manchuria and Korea, is cultivated today in Korea. Any literature about the organic components of "Astragalus Membranaces Bunge" has been extracted with methanol referring to a literature of "Panax Ginseng C.A. Meyer" and two kinds of colorless crystals were obtained. After recrystallization in absolute alcohol, the melting point has been measured. The one kind was 181-182℃ and the others, 184-186℃ respectively. It does not contain nitrogen, sulfur and halogen. By Liebermann's reaction, the one kind was not a carbohydrate but might be a Saponin. Through paper chromatography, taste, melting point, spectrophotometry, and elemental analysis, it was concluded that the other was Sucrose. It has been notified that the compound can be crystalized at the proper temperature, purity, and concentration of the solution and also solvent system.
