[New chemical constituents from Radix Polygoni Multiflori after processing].
OBJECTIVE
To study the new chemical constituents from Radix Polygoni Multiflori after processing.


METHODS
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.


RESULTS
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).


CONCLUSIONS
It is the first time that compound I and 1I were isolated from Polygoni.
