本发明公开了一种分析红藻细胞内的DA分布与含量的方法，在分析DA分布中，将新鲜天然红藻组织进行固定，利用新急速冻结置换法制成切片，再加入DA抗体进行免疫组织化学染色，在显微镜下观察样品中的DA位置情况；在分析DA含量中，将处理后的混合物放入离心机，转速设定为3500rpm，离心16m i n，结束后取上清液。再进行一次重复试验，再次提取红藻中的软骨藻酸。把在之前的操作中提取出的上清液合并，用纯水定容到20mL后，然后用0.45um滤膜进行超过滤，所制成的试验液进行LC/MS检测，对所得数据进行分析统计处理。此方法最大限度的保留红藻内的DA及细胞内部结构，降低在处理过程中DA的流出量，可以更清晰的对其进行观察，所取得的效果更优于目前的其他方法。
