| Abstract: | Quantitative analysis of L pyroglutamic acid in Gastrodia elata Bl. collected from different origins and prepared through different procedures were carried out by HPLC. The results indicated that the contents of L pyroglutamic acid in different G. elata varied differently as to their habitats, cultivation and preparative processes. As an overall result, it is clear that the concentrations of L pyroglutamic acid in wild and fresh G. elata are higher than that of the cultivated and dried varieties. |
| Keywords: | Gastrodia elata Bl. L pyroglutamic acid HPLC quantitative analysis |
