英文摘要:

From the 95% EtOH extract of the cortexes of Polygala tenuifolia, four new phenones and three known xanthones were isolated. The structures of the four new phenones were identified as 4-O-[alpha-L-rhamnopyranosyl(1 -> 2)-beta-D-glucopyranosyl]-2-hydroxyl-6-methoxybenzophenone (tenuiphenone A, 1), 3,5-di-C-beta-glueopyranosyl-2,4,6,3′-tetrahydroxybenzophenone (tenuiphenone B, 2), 21,41,6′-trihydroxyphenyl-(24Z)-triacontene-1-one (tenuiphenone C, 3), 2′,4′,6′-trihydroxyphenyl-(26Z)-dotriacontene-1-one (tenuiphenone D, 4) respectively, on the basis of spectroscopic analyses. The isolation of I and 2 supplied an evidence for the hypothesis that xanthone was biosynthesized from benzophenone in the plants.
