Effects of choline chloride(CC) on antioxidative metabolism,permeability of cell membrane,chlorophyll fluorescence parameters and catalpol content of Rehmannia glutinosa were studied by spraying CC solutions in diffreent concentrations(0,100,300,500 mg/L) on the leaves of Rehmannia glutinosa subjected to drought stress.

Optimization of the Extraction Process for Catalpol from the Dry Leaves of Rehmannia glutinosa Libosch by Orthogonal Experiment;

Effect of catalpol,berberine,and their combination on insulin resistant 3T3-L1 adipocytes;

Dual direction regulatory effect of catalpol on β-adrenergic receptor and M-cholinergic receptor;

Fragmentation regularity of gmelinol by time-of-flight mass spectrometry;

Study on the determination of alcohol content in rice vinegar by fast oxidation method;

The method of chemical oxidation to measure alcohol content in liquor was introduced in this paper.

In fermentative process the alcohol content variation was measured.

The results showed that the salt added into culture medium had significant effect on yeast's growth, especially CanV yeast; the decrease of reducing sugar content and increase of ethanol content was related to different growth phase of each yeast.
