Study on the Best Initial Processing Technology of Gastrodia Elata

The effects of different initial processing methods on the amount of gastrodin and gastrodigenin isolated from Gastrodia elata Blume were investigated and the best initial processing technology was optimized. The contents of gastrodin and gastrodigenin were analyzed by high performance liquid chromatography (HPLC). It is established that G. elata boiling in water followed by ethanol extraction is the best initial processing technology, which can provide the basis and reference for the standardized processing of G. elata herbs.
