Summary:To study the new chemical constituents from Radix Polygoni Multiflori after processing. Various kinds of chromatographic methods were used to deparate the chemical constituents from Radix Polygoni Multiflori after processing. Their structures were determined by NMR and MS spectral data. The two new compounds were 2,3-dihydro-3,5-dihydroxy-6-meth-yl-4 (H)-pyran-4-one(I) and 5-hydruoxymethyl-furfuran(II). It is the first time that compound I and 1I were isolated from Polygoni.
