-15℃低温技术在长期储存冬虫夏草、西洋参中的应用

Applied Investigation of Long-Term Storage of Cordyceps and Ginseng under -15℃

目的为解决大量冬虫夏草、进口西洋参等名贵中药材在长期储存中质量稳定、安全可靠的问题。方法从1990年初起,根据药材的不同性质,恰当控制含水量后分装,采用-15℃低温技术储存药材至2008年。结果18年来,冬虫夏草按1985年版《中国药典》性状项进行质量检查,西洋参按国家卫生部进口药材标准(WS4-16-86)性状和含量测定项进行检查,结果均符合规定。结论该研究突破了国内外均未见报道的名贵中药材0℃以下低温储存研究这一盲(禁)区,初步解决了名贵中药材长期储存时的质量稳定问题。

Objective To investigate the application of long-term storage of large quantity of rare Chinese herbal medicine such as Cordyceps Sinensis Sacc and imported Canadian Ginseng for resolving the problems of quality and safety control in long- term storage. Methods According to different characteristics of herbs, we packaged them after appropriate water-control, followed by low-temperature storage at-15℃ since 1990. Results In the recent 18 years, the quality examination of Cordyceps sinensis Sacc was performed according to the item of character inspection in the Chinese Pharmacopoeia（1985 edition）, which of Panax quinquefolium L. also was performed according to the items of character and quantity in the Imported Raw Medicine Standards published by Public Health Ministry （WS4- 16- 86）. All results conformed to the regulations. Conclusion This research has broken through the blind （forbidden） zone of rare herbs＇ low- temperature storage under 0 ℃, which has not been reported both in home and abroad. The quality stable problem in longterm storage of rare Chinese herbal medicines is initially resolved.
