Non-identity of hortensin from Millingtonia hortensis with 3,4′-dihydroxy-6,7-dimethoxyflavone
摘要:
Hortensin, isolated from M. hortensis and analysed as 3,4'-dihydroxy-6,7-dimethoxyflavone, has been found to be different from a synthetic sample. Reinterpretation of the reported data and comparisons with authentic samples show that hortensin is 5,4'-dihydroxy-6,7-dimethoxyflavone (cirsimaritin).
