[Abstract]
Object<\b> To study the low polarity constituents of Gastrod iaelata Blum e . Methods<\b> The constituents were isolated by column with prepared TLC, and identified by NMR, MS spectra. Results<\b> Seven compounds were isolated and identified. They were p-hydroxybenzyl ethylether (Ⅰ),β - sitosterol( Ⅱ ), palmiticacid (Ⅲ), 2, 2 ′ - methy lenebis ( 6- tert- buty l- 4- methy lphenl)(Ⅳ), p - hydroxybenzy lmethylether (Ⅴ), dimethyl phthalate (Ⅵ), p- hydroxybenzaldehyde (Ⅶ ) . Conclusion<\b> Two compounds wereis olated from G. elata firstly, and compound Ⅳ astetra- benzol- dimeris also isolated from the plants of Gastrodia R. Br. and Orchid aceae for the first time.
