Objective:
To study the chemical constituents of Syringa veutina Kom.
Methods:
The constituents were isolated and repeatedly purified on silica and Sephadex LH-20 column chromatography. They were dentified and structurally elucidated by spectral analysis.
Results:
Seven compounds were obtained. They were identified as Syningin(1), Liriodendrin(2), (+) -Medioresinol di-O-beta-D-glucopyranosied (3), Rutin(4), Quercetin 3-O-beta-D-glucopyranoside (5), Kaempferol-3-O-beta-D-glucopyranosied (6), D-mannitol (7).
Conclusion:
Compound 2 and 3 were isolated from this genus for the first time. Compound 4, 5, 6 and 7 were isolated from this plant for the first time.
