Abstract:
OBJECTIVE: To study the chemical constituents of Whole Plant to the whole plant of Veronicastrum axillare(Sieb. et Zucc.)Yamazaki. METHODS: The compounds were isolated and purified by various chromatographic techniques, and their structures were identified on the basis of physicochemical properties and spectral analysis. RESULTS: Twenty-three compounds were identified as 5-hydroxy-7, 4'-dimethoxyflavone(1), acacetin(2), 5, 7, 4'-trihydroxy-8-methoxyflavone(3), 5, 7, 3'-trihydroxy-4'-methoxyflavone(4), luteolin(5), oleic acid(6), syringaresinol(7), glyceryl ferulate(8), cinnamic acid(9), p-hydroxycinnamic acid(10), caffic acid(11), ferulic acid(12), 3, 4-dimethoxycinnamic acid(13), p-hydroxybenzoic acid(14), protocatechuic acid(15), vanillic acid(16), isovanillic acid(17), protocatechuic aldehyde(18), hydroquinone(19), 1, 2, 4-benzenetriol(20), D-mannitol(21), sucrose(22), and β-sitosterol(23). CONCLUSION: All the compounds are isolated from this plant for the first time except for compounds 2, 5, 19, 21 and 23, and from the genus Veronicastrum for the first time except for compounds 2, 5, 6, 12, 13, 19, 21 and 23. The 13C-NMR data of compound 8 is reported for the first time.
