TWO POLYPHENOL GLUCOSIDES AND TANNINS FROM ROSA CYMOSA

Two new polyphenol glucosides, rocymosins A and B, were isolated from Rosa cymosa and characterized as 3-O-(6'-O-galloyl)-β-D-glucopyranosyl-4-hydroxyphenethyl alcohol and 2'-O-β-D-glucopyranosyl-4,4',β-trihydroxy-dihydrochalcone, respectively.Eight known tannins, casuarinin, rugosin D, stenophyllanins A and B, (+)-catechin, procyanidin B-3, procyanidin B-3 3-O-gallate and catechin-(4α->6)-catechin-(4α->6)-epicatechin, were also isolated.
