Phenolic constituents from the rhizomes of Gastrodia elata.
Gastrodia elata Bl. (Orchidaceae) is an important traditional medicinal plant as well as a famous foodstuff in China. In the present article, the HPLC chromatograms of different preparation processes were reported, and structures of nine phenolic compounds, isolated from Gastrodia elata, were assigned. The isolated compounds were identified as 1,3-bis(4-hydroxybenzyl)citrate (1), gastrodin (2), 4-hydroxybenzyl alcohol (3), 1-(4-beta-D-glucopyranosyloxybenzyl)citrate (4), 4-hydroxybenzaldehyde (5), parishin B (6), 4-hydroxybenzyl methyl ether (7), 4-hydroxybenzyl ethyl ether (8), and 4-(4'-hydroxybenzyl)phenol (9). Compounds 1 and 4, named as parishin D and E, were new. Their structures were elucidated on the basis of spectral analyses, including 2D NMR spectroscopy.
