ABSTRACT
Ophiopogon japonicus is one of the commonly used medicines,and it has gradually become a therapeutic food for people's daily health care. O. japonicus in Sichuan province is the famous Dao-di herbs in Sichuan province,and is mainly produced in Santai county,Sichuan province. With the unique geographical advantage,Santai county plans to declare the new food raw materials of O. japonicus based on the geographical indication products( Fu Cheng O. japonicus),so it is necessary to analyze and evaluate the nutritional components of O. japonicus in Santai county. The experimental results showed that the content of the nutrients was characterized by low fat,high polysaccharide,high potassium and high vitamin B2,which can be developed as new food raw materials.

As a new hypnotic, zopiclone is widely used in clinical treatment. There are many methods for determination of zopiclone, including spectrophotometry, chromatography and chromatography mass spectrum, etc. Present paper reviews different kinds of biological samples associated with zopiclone, ex-traction and purification methods, and determination and analysis methods, which aims to provide refer-ences for the relevant research and practice.
ABSTRACT
Objective To determine the content of polysaccharide in Aloe barbadensis Miller and Aloe vera L. Var. Chinensis(Haw.)Berger. Methods Carubinose was used as reference substance, measured and compared polysaccharide content with the method of UV spectrophotometry at 610 nm absorbance of growth years for 1, 2, 3, 4 and 5 years of Aloe barbadensis Miller and Aloe vera L. Var. Chinensis(Haw.)Berger. Results The mannose and the absorbance was linear (r=0.998 5) in the range of 0.05 - 0.60 g/L, and the content of Aloe barbadensis Miller polysaccharide in the measured growth period was respectively 1.201, 1.485, 1.665, 2.355 and 5.040 mg/g. The content of polysaccharide in Aloe vera L. Var. Chinensis(Haw.)Berger was 0.780, 0.900, 1.035, 1.650 and 2.355 mg/g. Conclusions The content of polysaccharide in Aloe barbadensis Miller and Aloe vera L. Var. Chinensis(Haw.)Berger differed in growth years, which increased with aging and polysaccharide content in the same age of Aloe barbadensis Miller was significantly higher than that of the Aloe vera L. Var. Chinensis(Haw.)Berger.
