| Abstract
|
| [Objection] To investigate the changes of contents of Morroniside and Loganin in Fructucs Corni by Different Processes.[Methods] Detecting the contents of Morroniside and Loganin in crude products and processed ones with HPLC.[Results] During processing,the content of iridoid glycosides decreased.Especially steaming with salt-water,the content of Morroniside was decrease from 1.70% to 1.02%,the downgrade rate was 40%;the content of Loganin was decrease from 0.92% to 0.89%,the downgrade rate was 3.3%.[Conclusion] The content of prepared Morroniside were lower than those of the crude herb,and the content of Loganin were stable,it offered evidence in processing mechanism of Fructus Corni. |
