From the MeOH extract of the aerial part of Gastrodia elata Blume (GEB) (Family: Orchidaceae), eight compounds have been isolated on repeated column chromatography, and their structures were elucidated as dotriacontanoic acid (1), beta-sitosterol (2), 4-hydroxybenzaldehyde (3), docosanoic acid oxiranylmethyl ester (4), hentriacotanoic acid (5), octadecanoic acid (6), benzoic acid (7) and gastrodin (8) on the basis of their spectral evidences including EI-Mass and 2D-NMR spectrum. All of them were obtained from the aerial part of Gastrodia elata Blume for the first time, in which compound 4 is a novelty to our best knowledge. It is also known that a phenolic glucoside, gastrodin is a major constituent just like Gastrodia rhizome.
