ABSTRACT
The contents of schisandrin, schizandrin A, B and C were determined by HPLC, and the effects of the climate factors and altitude on lignin contents were analyzed in order to select the optimal cultivation area of S. chinensis. The lignin contents were analyzed by HPLC using a ZORBAX SB-C18 column (4.6 mm x 250 mm, 5 microm). The column temperature and detection wave length were set at 35 degrees C and 254 nm, respectively. Methanol-water was used as the mobile phase in gradient elution mode and the flow-rate was 1.0 mL min(-1). The method had a good repeatability, stability and accuracy. The correlation of climate factors and lignins contents was analyzed by SPSS software. The results showed that the schizandrin A content in S. chinensis fruits were higher than 0.4% in Ji'an, Liuhe, Antu and Fusong in Jilin province, which met the quality requirement. It had significant linear negative correlation relationship between schisandrin, schizandrin A, B and altitude, the contents decreased with the increase of altitude. The significant negative linear fitting coefficient was 0.844 1 between schisandrin and altitude; but it had not significant correlation between schizandrin C and altitude. A significant positive correlation of climate factors and the contents of S. chinensis lignins were mainly the temperature factors (the average annual temperature, the highest temperature in July, the average temperature in July, the highest temperature in January, the average temperature in January) and precipitation factor (average annual precipitation), which reveals that higher temperature and precipitation were helpful to the formation and accumulation of lignins of S. chinensis. So the cultivation area of S. chinensis should be in the low elevations region with warm and rainy climate.
