Abstract:
OBJECTIVE: To study the chemical constituents of Dendrobium officinale protocorm. METHODS: The compounds were isolated and purified by means of column chromatography, and their structures were identified on the basis of spectroscopic data and comparison with standard literature data. RESULTS: Eight compounds were isolated from the(CH3)2CO, CHCl3 and 95% EtOH fractions of the EtOH extract, and identified as 1-O-p-feruloyl-β-D-glucopyranoside(I), arillatose B(II),4-β-D-glucopyranosy-loxy)benzyl alcohol(III), 4-hydroxymethyl-2,6-dimethoxyphenyl-β-D-glucopyranoside(IV), n-hexatriacontanoic acid(V), n-heptaco-sanol(VI), β-sitosterol(VII), and cycloart-23-ene-3β,25-diol(VIII). CONCLUSION: All these compounds were isolated from the protocorms of D. officinale for the first time. Compounds I, II, III, IV, and VIII were obtained from Dendrobium genus for the first time.
