互花米草茎叶矿质元素提取潜力分析

Extraction Potential of Mineral Elements from Spartina Alterniflora

外来入侵物种互花米草内含丰富的矿质成分,对其组织矿质成分的提取与表征是互花米草进行资源化利用的重要基础之一。本研究拟通过3种试验方法(榨汁不脱色法、双氧水脱色法、活性炭脱色法)提取互花米草矿质成分并比较分析,探究不同方法矿质成分的提取潜力。结果表明,互花米草K、Na、Ca、Mg等元素含量在3.74~101.1g/kg之间,具有较好的矿质成分提取潜力。双氧水脱色法得到的茎产品中矿质元素含量比其他两种方法得到的矿质元素含量高8.47%~35.31%,活性炭脱色法得到的叶片中矿质元素含量比其他两种方法得到的矿质元素高5.59%~23.48%,所以,提取茎中的互花米草矿质元素采用双氧水脱色法较为合适,但提取叶片中的矿质元素采用活性炭脱色法较为合适。

Spartina alterniflora contains abundant mineral constituents.The extraction of mineral constituents from its tissues is one of the important resource utilization of Spartina alterniflora.This study intends to extract the mineral components of Spartina alterniflora by three test methods(juice without decolorization,hydrogen peroxide decolorization and activated carbon decolorization) and explore the extraction potential of the mineral components of different methods.The results show that the contents of K,Na,Ca,Mg and other elements of Spartina alterniflora range from 3.74 g/kg to 101.1 g/kg.It has good mineral extraction potential.The content of mineral elements in stem products obtained by hydrogen peroxide decolorization is 8.47%~35.31% higher than that obtained by the other two methods,and the content of mineral elements in leaves obtained by activated carbon decolorization is 5.59%~23.48% higher than that obtained by the other two methods.Therefore,the decolorization with hydrogen peroxide is more suitable for extracting mineral elements from stems of Spartina alterniflora,while the decolorization with activated carbon is more suitable for extracting mineral elements from leaves.
