Abstract:
Objective To study the chemical constituents of Dendrobium bellatulum. Methods The compounds were isolated and purified by column chromatography and preparative HPLC, and their structures were elucidated by spectral analysis. Results Fifteen compounds were isolated and identified as 2-hydroxy-4-methoxy-3,6-dimethylbenzoic acid (1), 4’,5-dihydroxy-3,3’- dimethoxybiphezyl (2), 3,3’-dihydroxy-4,5-dimethoxybiphezyl (3), dihydroconiferyl dihydro-p-coumarate (4), aloifol I (5), batatasin III (6), dendrosinen B (7), 2,5,7-trihydroxy-4-methoxy-9,10-dihydrophenanthrene (8), p-hydroxyphenyl-propionic acid (9), p-hydroxycinnamic acid (10), ferulic acid (11), caffeic acid (12), dendrosinen D (13), neoolivil (14), and 3-hydroxymethyl-9- methoxy-2-(4’-hydroxy-3’,5’-dimethoxyphenyl)-2,3,6,7-tetrahydrophenanthro [4,3-b] furan-5,11-diol (15). Conclusion All compounds are isolated from D. bellatulum for the first time, and compound 1 is isolated from the family Orchidaceae for the first time.
