Abstract

The present invention provides a pharmaceutical composition containing proteoglycan extracts of algae and a process for preparing proteoglycan extracts from the algae.

Description

technical field [0001] The present invention relates to the extract of algal organisms and its application, especially the extraction and application of algae proteoglycan. Background technique [0002] Since the 1970s, people have paid more and more attention to the research on algae, especially blue-green algae. At first, people's research on algae mainly focused on its nutritional value and toxicity. At the United Nations Food and Agriculture Organization meeting held in 1974, spirulina was considered to be an excellent food resource for human beings in the future. [0003] However, the understanding of the medicinal effects of algal organisms began in the 1980s. People mainly focused on the performance of various algae extracts. attention. [0004] In Japanese Patent Publication Showa 58-12832, it is reported that proteoglycans extracted from Chlorella and Spirulina have the function of inhibiting leukemia cancer cells, but this document does not disclose other therape...
