Abstract:
Objective: To study the chemical constituents from the stem barks of Engelhardtia roxburghiana. Methods: The compounds were isolated and purified by various chromatographic techniques and their structures were elucidated by spectral analysis. Results: Ten compounds were obtained and identified as eudesm-4(15)-ene-1β, 6α-diol (1), (4S)-4-hydroxy-1-tetralone (2), (-)- regiolone (3), p-hydroxybenzoic acid (4), kaempferol (5), isolicoflavonol (6), broussoflavonol F (7), broussonol E (8), kaempferol-3-O- α-L-rhamnoside (9), and quercetin-3-O-α-L-rhamnoside (10). Conclusion: Compounds 1, 4, and 6-8 are isolated from the plants of Engelhardtia Leschen. et Bl. for the first time, and the prenylated flavonoids are firstly reported in this genus.
