Abstract:
Objective: To study the chemical constituents from the peeled dried roots and stems of Syringa pinnatifolia. Methods: The chemical constituents from the peeled dried roots and stems of S. pinnatifolia were isolated and purified by silica gel and Sephadex LH-20 column chromatography, and preparative HPLC. The structures were identified by spectral methods. Results: Three compounds were obtained and identified as lignan, namely 3, 3', 4-trimethoxy-4', 8, 9, 9'-tetrahydroxy simple lignan (1), 3, 3', 4, 9-tetramethoxy-4', 8-dihydroxy-9'-ethoxy simple lignan (2), and 3, 3', 4, 9-tetramethoxy-4', 8, 9'-trihydroxy simple lignan (3). Conclusion: Compounds 1-3 are new, named syripinnalignan C, syripinnalignan D, and syripinnalignan E.
