| 英文摘要 | The complete assignments of all the (1)h and (13)c nmr signals of three polyhydroxylated 12-ursen-type triterpenes, 6 beta,19 alpha,22 alpha-trihydroxyurs-12-en-3-oxo-28-oic acid (1), 3 beta,6 alpha,19 alpha,23-tetrahydroxyurs-12-en-28-oic acid (2) and 3 beta,6 beta,19 alpha,23-tetrahydroxyurs-12-en-28-oic acid (3), were carried out by means of homo- and hetero-nuclear two-dimensional nmr experiments. compounds 1-3 were isolated from the aerial parts of dischidia esquirolii. of them, 1 and 2 were identified as new polyhydroxylated ursolic acid derivatives. compound 2 is the c-6 hydroxyl epimer of 3, which was isolated first from adina rubella, and its structure is revised in this paper. copyright (c) 2008 john wiley & sons, ltd. |
