摘要：
The original structure of hortensin, from Millingtonia hortensis, and analysed as 4'-hydroxy-6,7-dimethoxyflavonol, has been changed once to 5,4'-dihydroxy-6,7-dimethoxyflavone (cirsimaritin). A further reinterpretation of the NMR data of newly isolated 'hortensin' showed that it is 5,7-dihydroxy-6,4'-dimethoxyflavone (pectolinarigenin). Several related flavonoids from the same plant were also identified.
