The Study Of Caring And Storing On Roots Of Angelica Sinensis And Codonopsis Pilosula

The origin of Chinese traditional medicine development begins with the application of fresh herbs. At first, human gradually learned and accumulated the effect of Chinese medicine to treat illnesses and keep fitness in production practices. With the progress of society and the deepening of people’s awareness to traditional Chinese medicine, the processing and storage technologies of Chinese herbal medicine were emerged to ensure the efficacy and achieve annual medication. For pursuit the higher values, there has been repeated instances of sulfur fumigation and other adverse effects of human drug safety in the processing and storage. Therefore, the use of fresh herbs is the requirements people back to nature and the way to ensure drug safety. Meanwhile, the food issues of medicinal and edible herbs will be resolved.Fresh Angelica sinensis and Codonopsis pilosula roots were used to study and analyze the effects of two factors storage shelf life of fresh herbs to meet the requirements of fresh herbs used. Four factors, moisture, heat, irradiation and preservative(liquid) were set up and stored under the refrigeration condition and the normal temperature, respectively to observe and determine the appearance and internal quality changes in the experiment. The main findings are as follows:1, There was not significant changes in total ash and extract content of Angelica sinensis and Codonopsis pilosula roots, but significant changes was found in volatile oil and ferulic acid contents with the changes of water content of Angelica sinensis and Codonopsis pilosula roots in refrigeration or storage at room temperature.2, Angelica sinensis roots treated by the hot water in 95 ℃ by and steam showed the lower moldy, rotting rate, and going lower oil rates under refrigeration storage, which were 2%, 0%, 5%; Codonopsis pilosula roots showed the higher mildew rates, decay rates were higher, which were 30% and 40%.3, Angelica sinensis and Codonopsis pilosula roots were preserved well after the irradiation treatments during the storage period of six months, in which moldy, rotting rate and going the oil rate were not more than 7%. Extract content of the Angelica sinensis and Codonopsis pilosula roots with 50-59% water content were 53.7% and 69.7% after the treatment of 9 k Gy radiation intensity.4, The effect of Angelica sinensis roots preservation was better overall, which showed no obvious going the oil, mildew, rot phenomenon in the concentration of 0.15 g·ml-1 of potassium sorbate as a preservative or salt concentration of 7% as the preservation solution. Codonopsis pilosula roots with the water content of 60% or more was rotted under all kind of fresh liquid filling.The keeping storage method for fresh Angelica: fresh Angelica sinensis roots were in 95 ℃ hot water about 1min, or Angelica sinensis roots were in the concentration 0.15 g·ml-1 of potassium sorbate treatment and was vacuum-packed and frozen. The content of the extract, volatile oil and the ferulic acid were the highest after determination about six months, which were 60.9%, 0.407%, 0.089%, respectively in line with the "Chinese Pharmacopoeia"(2010 version) requirements; keeping storage for fresh Codonopsis pilosula roots method was 9 k Gy radiation treatment, vacuum-packed, refrigerated, with total ash content of 3.2%, the highest extract content of 69.7% in line with the "Chinese Pharmacopoeia"(2010 version) requirements.
