Abstract:
Objective To study the chemical constituents from ethanol extracts of the stems of Dendrobium aphyllum. Methods Ten compounds were isolated by silica gel, Sephadex LH-20 column chromatography and reversed-phase semi-HPLC. Results Ten compounds were identified by analyzing their spectral data and comparing with the previously reported literatures as 4,7-dihydroxy-2- methoxy-9,10-dihydroxyphenanthrene (1), 2,4-dihydroxy-7-methoxy-9,10-dihydroxyphenanthrene (2), 4-methoxy-2,5,7,9-tetrahydroxy- 9,10-dihydrophe-nanthrene (3), 5-methoxy-4,7,9-trihydroxy-9,10-dihydrophenanthrene (4), pinoresinol (5), eugenol-β-D-glucoside (6), trans-ferulic acid (7), dodecan-1-ol (8), β-sitosterol (9), and β-daucosterol (10). Conclusion All compounds are isolated from this plant for the first time.
