Objective To establish the fingerprints for characterization of the chemical components of maidong(root of Ophiopogon japonicus) in two main cultivate regions of China,Sichuan(Chuanmaidong) and Zhejiang(Hangmaidong).

Selection and study of the microorganism for the extraction of saponins from Ophiopogon japonicus;

Study on Extraction Process of Polysaccharide in Ophiopogon japonicus;

Antioxidant Activities of Extracts from Ophiopogon japonicus;

Identification of Radix Liriopes and Radix Ophiopogonis by Electrospray-Mass Spectrometry Characteristic Spectra Analysis;

Studies on the Leaching of Active Aluminum from Chinese Herbals Radix Ophiopogonis and the Distribution of Aluminum Species by Chemical Extraction;

HPLC fingerprint analysis of Radix Ophiopogonis;

The filmed drilling cultivation technique of winter wheat is a new breakthrough technique to win high yield for the dry land wheat and the late sowing wheat,coupled with a complete sowing and filming train planter supporting efficient operations,and increasing output significantly.

The advanced main factor regression analysis was applied to winter wheat s climate analysis in this article, in which the practicality and science character of this method were embodied, eventually it was set that the temperature is the main climate element which affect on winter wheat s regreening and the precipitation is the main climate element which affect on winter wheat s yield.

The favourable seeding-time for drilling winter wheat covered with the plastic film are longer and later than that for conventional winter wheat on open plots.

Separation and Identification of New Furosteroidal Saponin from Ophiopogon japonicus(Thunb.) Ker-Gawl;

Studies on latent infection and overwintering of anthracnose pathogen in Ophiopogon japonicus in winter in Sichuan province;

New Steroidal Glycosides from Ophiopogon japonicus;
