    Abstract:

    The target of this manuscript was to extract,purify and identify an organic iodide with the iodine supplementation activity from kelp.The maximum yields of organic iodine and total iodine were obtained when the kelp was extracted in 50~55 ℃ for 10~12 h and then 79% of organic iodine was recovered from kelp in the isoelectric precipitation in pH 5.0-5.3.At last,80 mg pure organic active iodide was acquired through paper chromatography.By compared with that of the standard material and determined by mass chromatogram and infra-red spectrogram,the purified compound with iodine complementing function was identified as 3,5-diiodo-l-tyrosine(DIT).
