2007 to 2009 on medicinal plants the Angelica (Angelicas inensis (bliv.) Diels) and the astragalus (RadixAstragali Bunge) using different drying methods and storage conditions of storage research, aimed at screening the best drying and storage conditions, The results are summarized as follows: 1. different drying methods have a significant impact on the content of active ingredients of the Angelica vacuum freeze-drying the highest content of volatile oil, ferulic acid and extract content is low, should drying origin processing method, drying method with the dry the temperature rises Angelica active ingredient content decreased significantly, the original processing method to 40 ° C drying effect is more ideal. Angelica long-term storage, dry vacuum bag packaging and storage of the exhaust shelf effect, weight loss, extract and volatile oil content; cleaning vacuum pumping packaging on Fresh Angelica fresh storage, sorghum combined with low temperature storage is an ideal smaller, weight loss, long shelf life, but from the volatile oil and extract content into account, should be used to dry Angelica herb storage is appropriate. 3 factors that affect angelica extract content of primary and secondary relationship in order for the water content> Packaging> temperature, the best storage conditions charge CO 2 Package 5 ° C storage, 13% of the water content, extract content up to 65.54%. Impact Angelica ferulic acid content of primary and secondary factors were packing method> water content> temperature, the best storage conditions for charge CO 2 Package 5 ° C storage, moisture content of 13%, ferulic acid content up to 0.045%. Affect angelica volatile oil content of primary and secondary factors were temperature> packaging> moisture content, the best storage conditions for vacuum packaging, 5 ° C storage, a water content of 10%, volatile oil content of up to 0.45%. 4 vacuum freeze-drying a large extent to ensure the appearance and color of the astragalus, easy processing and storage, has high practical value and application prospect. Judging from the active ingredient, 50 ° C drying time is short, high active ingredient content, is an ideal choice. Astragalus long-term storage should be selected dry Astragalus vacuum bag exhaust packaging and storage, weight loss, extract and polysaccharide content; preservation storage of fresh Astragalus, sorghum liquor cleaning the vacuum pumping packaging is an ideal combination of low temperature storage, Weight loss is smaller, long shelf life, but considering the polysaccharides and extract content, dry Radix Astragali storage is appropriate. Primary and secondary factors affect Astragalus extract content were packing method> water content> temperature, the best storage conditions for charge CO 2 Packaging 25 ° C storage, 10% water content, extract content up to 50.72%. The influence of polysaccharides of primary and secondary factors were packing method> temperature> water content, the best storage conditions for 5 ° C to charge CO 2 packaging, water content of 13%, the polysaccharide content of up to 7.41%. Primary and secondary factors affect Astragaloside content were packing method> water content> temperature, the best storage conditions for the charge CO 2 Packaging 5 ° C storage, the moisture content of 16%, astragaloside up 0.087%.
