Jasmonic acid significantly increased ginsenoside content in ginseng adventitious roots in flask and bioreactor cultures. In flask culture, ginsenoside content increased by the addition of jasmonic acid, resulting in the highest ginsenoside content at 10 mgl-1 jasmonic acid. However, the root growth was strongly inhibited by increasing jasmonic acid concentration. Fresh weight, dry weight, and growth rate of the roots decreased as jasmonic acid concentration increased. The highest ginsenoside yield was obtained at 2.0mgl-1 jasmonic acid. In a two-stage culture ina balloon type airlift bioreactor, the content of total ginsenoside and protopanaxadiol ginsenosides increased by over 5 times after 7 days of jasmonic acid treatment but the contents of Rg group ginsenosides increased insignificantly.

This paper puts forward a quick-freezing method by putting the ultralow temperature medium into a negative pressure. Through the experiment, it indicated the speed and quality to refrigerating water under the condition of negative pressure. Based on that, it designed a quick-freezing device. Meanwhile this paper researched on how to quick-freeze products in bags by adopting this device. After being testified by the experiment, it proved that this device had improved the quick-freezing efficiency and the refrigerating effect.
