Abstract
[Objective] To explore changes of polyphenol content of Prunus humilis Bunge introduced in Chengdu during growing period and provide theoretical basis for researching polyphenol content of Prunus humilis Bunge.[Method] We determined the polyphenol content of Prunus humilis Bunge introduced in Chengdu during growing period by tartaric acid iron assay.[Result] The polyphenol of Prunus humilis Bunge extracted by using 95% methanol was the best,and the content of polyphenol of Prunus humilis Bunge would not accumulate internally in plants.The content of polyphenol reached higher in around 12:00 and when the temperature was higher in the evening,it would be the minimum at 14:00 when the temperature was the lowest,and the content was also very low in about 19 ℃;the content of polyphenol would increase under herbivore stress.[Conclusion] Polyphenol has important effect on metabolism of plant.The content of its fresh leaves of plants can reflect the intensity of secondary metabolism,the reaction of plant adaptation to the environment,and resistance to various environmental stresses.关键词
