ABSTRACT
Objective: To study the chemical constituents from Stelleropsis tianschanica. Methods: The constituents were isolated from S. tianschanica and purified by column chromatography, and the structures were identified by spectral analysis and chemical methods. Results: A total of 12 compounds were isolated from S. tianschanica, including seven flavonoids compounds, two lignans compounds, and the other three compounds, and the structures were identified as wikstrol A (1), wikstrol B (2), viburnolide A (3), genkwanol B (4), genkwanol C (5), stelleranol (6), dipropyl phthalate (7), diisobutyl phthalate (8), 1,3,5-triol-2-methoxybenzene (9), coniferin (10), syringin (11), and acacetin (12). Conclusion: Compounds 1-2, 5-6, 9-12 are isolated from the genus Stelleropsis for the first time.
