[New ellagic glycosides and known triterpenoids from Duchesnea indica Focke].[Pubmed:
9863255]
METHODS AND RESULTS:
Two new ellagic glycosides, named Ducheside A and ducheside B, have been isolated from Ducheside indica Focke. Their structures were established as 3'-O-methyl-ellagic acid-4-O-beta-D-xylopyranoside (I), 3'-O-methyl-ellagic acid-4-O-alpha-L-arabinofuranoside (II), respectively, on the basis of chemical method and spectral analysis. In addition, four known compounds were isolated and identified as 3 beta-hydroxylurs-12-en-28-oic acid (III), 2 alpha, 3 beta, 19 alpha-trihydroxylurs-12-en-28-oic acid (IV), 2 alpha, 3 beta, 19 alpha-trihydroxylurs-12-en-28-oic acid 28-O-beta-D-glucopyranoside (V), 2 alpha, 3 alpha, 19 alpha-trihydroxylurs-12-en-28-oic acid 28-O-beta-D-glucopyranoside (VI).
CONCLUSIONS:
Compounds IV, V, VI were isolated for the first time from Duchesnea genus.
