Abstract:
Objective: To study the chemical constituents from Dendrobium hancockii. Methods: The compounds were isolated and purified by column chromatography and preparative HPLC, and their structures were elucidated by spectral analysis. Results: A total of nine compounds were isolated from D. hancockii and the structures were identified as 3,α-dihydroxy-4,5,3’- trimethoxybibenzyl (1), 3,4’,5-trihydroxy-3-methoxybibenzyl (2), 4,4’-dihydroxy-3,5,3’-trimenthoxybibenzyl (3), 4,3’-dihydroxy- 3,5’-dimethoxybibenzyl (4), 7-hydroxy-2-methoxy-1,4-phenanthrenequinone (5), 2,5-dihydroxy-4-methoxyphenanthrene (6), 2,5-dihydroxy-4,9-dimethoxyphenanthrene (7), nobilone (8), and crepidatuol B (9). Conclusion: Compound 1 is a new compound named dendrohanol A, and compounds 2-9 are isolated from this plant for the first time.
