Effects of Growth Period on the Polysaccharide Content in RADIX OPHIOPOGONIS
摘要
Abstract
[Objective]To study the correlation rules of polysaccharide content in RADIX OPHIOPOGONIS with different growth periods, to determine the characteristic quality, and to provide scientific basis for CAP quality control and for resources rational exploitation and utilization of RADIX OPHIOPOGONIS. [ Method] In situ dynamic method was used for the main production area for RADIX OPHIOPOGONIS (3 years old). Root tuber samples with 0.5, 1, 2 and 3 years old were randomly collected. The washed fresh root tubers were dried at -50X1. Polysaccharide content in each treatment was detected by phenol-vitriolic colorimetry. Correlation rules of polysaccharide content in RADIX OPHIOPOGONIS with different growth periods were analyzed by SPSS17.0 software. [Result] The average content of polysaccharide in RADIX OPHIOPOGONIS with different growth periods was between 17.68% and 34. 86%. With the growth of root tuber, polysaccharide content showed extremely significant positive correlation (p<0.001 ). The regression equations were as follows; y, = 9. 1261n(x) +24. 58(r2 = 0.980) and y1 =9.0651n(a:) -28.85(r2 =0.981). [Conclusion] The content of polysaccharide which was a secondary metabolite was closely related to the growth period. There was scientific basis for harvesting at 3 years old. It was proper to collect one year after plantation, because in the summer and fall of the second year, a large amount of root tubers became rotten due to the high temperature and humidity关键词
